Welcome to Power Macintosh

Congratulations on the purchase of your new Macintosh. Your computer is designed to give you the highest performance combined with real ease of use—it’s easy to set up, easy to use, and easy to expand. This book will guide you through the setup procedure, tell you how to expand your Macintosh, and provide many tips on using your new system.

Your Macintosh computer is powered by the new † microprocessor (or “chip”). This microprocessor was designed by Apple Computer, Inc., Motorola, Inc., and IBM Corporation. The † microprocessor uses Reduced Instruction Set Computing (RISC) technology to deliver very high performance at the lowest possible cost. The † RISC mi c roprocessor represents the state of the art i n microprocessor design.

Your new Macintosh will run almost all your existing Macintosh software, but for best performance and greatest speed, look for the new software programs designed especially for Power Macintosh computers. You’ll find Power Macintosh programs at any software store that carries products for Macintosh.

IMPORTANT

When picking up your computer, be sure to grasp it by the sides.

Grasping it by the front or back can cause the computer’s cover to lift off.

When lifting or carrying the computer, always grasp it by the sides, as shown. Do not lift or carry the computer by grasping the front and back.

Pluggin g in the computer

Before you plug your Macintosh into a wall socket, carefully read all the setup instructions in this chapter. T h en, before you connect anything to your Macintosh, follow the instructions in this section to plug it in. The plug grounds the computer and protects it from electrical damage while you are setting up. When you are ready to begin, follow these steps:

1Make sure the voltage switch on the back of the computer is set for the kind of voltage

system to which you will be connecting.

The voltage switch must be set correctly to avoid damaging your computer. If you don’t know the voltage used in the country you’re in, refer to the table “Voltages for Different Locations” later in this chapter.

Getting Started

WARNING

Setting the correct voltage for your computer does not set the voltage for your monitor even if the monitor’s power cord is connected directly to your computer. To protect your monitor, b e sure to use the appropriate adapter or voltage converter, if one is necessary.

Check to see that the voltage switch on the back of your computer is properly set before you plug it in. If you need to change the setting, insert a small screwdriver here and slide the switch.

Set the switch to show “115” for voltages in the 100–130V range. Set the switch to show “230” for voltages in the 200–270V range.

IMPORTANT

If you need to turn off your computer at any point, please see “Turning the Computer Off” later in this chapter. It is very important to use the correct procedure for shutting down your Macintosh before turning it off.

Learning the basics

If you are new to the Macintosh, you should begin by looking at the easy-to-use program called the Macintosh Tutorial. The tutorial teaches you the basic skills you’ll need to use your computer. To start the tutorial, follow these steps:

1Slide your mouse along your mouse pad or desk.

Hold the mouse as shown, with the cable pointing away from you. Rest the heel of your palm on the desk and grasp the sides of the mouse between your thumb and fingers. Use your wrist and fingers to slide the mouse around with the index finger resting on the mouse button. Don’t press the mouse button (under your index finger). Notice that the arrow (8) on the screen moves in the same direction that you move the mouse.

Mouse button

If the arrow doesn’t move, make sure that the cables connecting the mouse and keyboard are secure and that your mouse is positioned as shown in the illustration.

Getting Started

2Move the tip of the arrow (8) to the question mark (h) in the upper-right portion of

the screen.

If you run out of room on your mouse pad or desk while moving the mouse, pick up the mouse and place it where there’s more room. (The arrow on the screen moves only when the mouse is in contact with the mouse pad or desk.)

3With the tip of the arrow on the question mark, press and hold down the mouse button.

A list of choices (called a menu) appears. This is the Guide (h) menu, which is the place to go when you have a question about how to use your computer.

4While holding down the mouse button, move the arrow until the words “Macintosh

Tutorial” are highlighted, then release the mouse button.

A window appears welcoming you to the tutorial. You can set this book aside for now and follow the instructions on the screen. When you have completed the tutorial, return to this book.

When you save energy, you save natural resources and reduce pollution. Your Power Macintosh contains features that automatically save energy. You can increase the energy savings by using the Energy Saver control panel to turn your computer off if you won’t be using it for a while—for example, overnight or over the weekend.

The Energy Star dialog box (shown in step 3 of “Turning the Computer On” earlier in this chapter) appears every time you start your computer until you open the Energy Saver control panel. Once you you open the control panel, you can accept the pre-set options shown there, or set your own energy-saving options. If you do not want to set your energy-saving options when the Energy Star dialog box is displayed, you can click Close Message or press Return (the Energy Star dialog box continues to appear when you start your computer).

Setting energy-saving options

You can get to the Energy Saver control panel by clicking Specify Settings in the En ergy Star dialog box that appears when you start your computer or by choosing Control Panels in the Apple (K) menu.

The Energy Saver control panel has pre-set options you can accept or you can specify different settings. To learn more about the Energy Saver control panel, refer to the information on saving energy in Macintosh Guide, available in the Guide (h) menu.

Getting Started

Putting your computer to sleep

Your Power Macintosh is pre-set to put itself to sleep after 30 minutes of inactivity. When your computer goes to sleep, the screen dims to save energy and to prevent images from “burning” into the screen. You do not lose any of the information you were working on even if you did not save it before the computer went to sleep.

To put your computer to sleep immediately, press the Power key on the keyboard or choose the Sleep command from the Special menu. You can set sleep options using the Energy Saver control panel, available under Control Panels in th e Ap ple (K) menu.

Tips for using Macintosh Guide

Here are a few tips for using Macintosh Guide effectively:

m Macintosh Guide is available only when you are in the Finder—the

desktop area where you can see the icons of disks, folders, and files. (Other programs may also have help available in the Guide menu, however.) If you don’t see Macintosh Guide in the Guide menu, pull down the Application menu (to the right of the Guide menu) and choose Finder.

m Foll o w the steps when you’re instructed to; don’t skip ahead or read

ahead. That way the computer can check to make sure you’ve done a step correctly.

m Unlike most windows, the Macintosh Guide window stays in front of

other windows on the screen so that your instructions are never covered. If you need to move the Guide window out of the way, drag it by the title bar at the top of the window.

You can also move the window out of the way by clicking the zoom box. Click the box once to shrink the window; click it a second time to expand the window to its original size.

m If you need more information about an instruction or a term, click the

button labeled “Huh?” to get further explanation. (The “Huh?” button is dimmed when no additional information is available.)

m If you want to return to the main Macintosh Guide window, click the

Topics (or h) button in the lower-left corner of the Guide window.

m When you’re finished using Macintosh Guide, click the close box in

the upper-left corner of the window.

Chapter 3

Connecting external ster eo speakers

You can take advantage of your computer’s stereo sound output by attaching externally powered (amplified) speakers.

1 Assemble the speakers and the cable you need.

You need a cable with stereo miniplugs at each end to connect one or both speakers to the computer. (Some speakers require a dual-plug adapter. Others, like those shown in the next illustration, accept a single stereo miniplug a nd are join ed by standard speaker wires.) You can also use a cable with RCA-style connectors.

2 Turn off the Macintosh. 3Plug a stereo miniplug into the sound output port (-) on the Macintosh.

If you’re using a cable with RCA-style connectors, you should plug them into the left and right audio output ports on the A/V panel instead.

4Plug a stereo miniplug into the Sound In port on one of the speakers.

If the speakers take a dual-plug cable, connect both plugs.

5Connect the speakers together with speaker wires, if necessary.

Your finished connections should look something like this:

Now you hear the computer’s sound through the external speakers. (You may also need to set options in the control panel for sound settings in order to hear sound through your speakers. Refer to the “Sound” topic of Macintosh Guide, available i n the Guide [h] menu for more information.)

Note: To control the volume of your external speakers, use the Video &Sound control panel to control volume and to set other options for playing sound through th e external speakers. If you are playing an audio CD, you may also need to adjust the volume control in the program you’re using to play CDs.

Connecting video equipment

You can connect video equipment to your Power Macintosh so that you can work with video images on the computer. With your Power Macintosh, you can view video on your monitor, capture single video images, and save digitized video i n files.

Your Power Macintosh can display and use video images from a variety of sources. To view video on your monitor, you connect video equipment to the video input port on the computer.

Your Macintosh can work with two video formats:

m S-video m composite video

S-video is a high-quality video format used by many video cameras and VCRs. Most televisions, most VCRs, and laserdisc players use the composite format. To find out which format your equipment uses, check the manual that came with your equipment.

Chapter 3

S-video connectors

The S-video connector is a round plug with several small metal pins. You can plug this type of connector into your computer’s S-video input port.

Connecting video equipment for input to the computer

When you connect video equipment to the Power Macintosh, you can view video on the computer, capture video frames, and hear the sound from the video equipment through the computer’s speaker. The instr uctions that follow are for connecting a stereo VCR or video camera, but you can use them as a model for connecting your computer to any video equipment.

Before you start, do the following: m Make sure that the VCR or camera has either a composite (RCA plug) port

or an S-video port.

m Place the VCR or video camera near the Macintosh. m Shut down the Macintosh and turn off the VCR or video camera.

Then follow these steps:

1 Assemble the cables you need to connect the VCR or camera to the Macintosh.

Depending on what kind of ports your VCR or camera has, you’ll need different cables (available at an electronics supply store).

m If your equipment has S-video ports, you’ll need the following cables:

Connecting Additional Equipment

Connecting external SCSI devices

Your computer has a port for connecting devices that use the Small Computer System Interface (SCSI, pronounced “skuh-zee”). The SCSI port permits high-speed communication between the computer and the device. The SCSI icon appears above the port on the computer’s back panel.

You can connect SCSI devices to the SCSI port in a chain. The first device in the chain plugs into the SCSI port; the second device plugs into the first device, and so on. SCSI devices commonly used with the Macintosh include hard disk drives, CD-ROM drives, scanners, some printers, and tape or cartridge backup drives.

You can attach up to seven external SCSI devices to the SCSI port. However, if you have a second internal hard disk connected to this SCSI chain you can attach only six external SCSI devices to the port. All SCSI devices connected to th i s chain must have their own unique ID number.

SCSI icon

SCSI port

Chapter 3

Note: In addition to the external SCSI port, your computer has a second, internal SCSI connection. The internal hard disk drive that came with the computer is connected to this internal SCSI interface. If your computer came with a CD-ROM player, it is also attached to the internal SCSI interface. An authorized Apple dealer or service provider can attach additional devices to the internal SCSI interface. For more information about the SCSI interfaces, see the Tec h n i c a l In for m at i o n booklet that came with your computer.

All devices on the same SCSI chain must have unique ID numbers, but devices on different SCSI chains may use the same SCSI ID number. (For example, you could have a CD-ROM player with ID number 3 connected to the internal SCSI chain and a tape drive with ID number 3 connected to the external SCSI chain.)

IMPORTANT

“Before You Connect a Device” and “Connecting a SCSI Device,” both later in this section, contain general instructions for attaching SCSI devices to your computer. Be sure also to follow the specific instructions that came with your external hard disk drive or other SCSI device when connecting the device to your Macintosh.

Before you connect a device

Before you connect a SCSI device to your Macintosh, be sure to complete these t asks:

m Make sure each SCSI device connected to your Macintosh has its own,

unique ID number from 0 to 6 (or from 1 to 6 if you have a second internal hard disk installed). See the instructions that came with each SCSI device for information on checking and setting its SCSI ID number.

IMPORTANT

If you use two or more devices attached to the same SCSI interface with the same ID number, your equipment could malfunction and you could lose data as a result.

m Make sure you have the appropriate cable for attaching the SCSI device to

your Macintosh. If the device is the first or only one you’re connecting, use a SCSI system

cable to connect it to the computer’s SCSI port:

SCSI system cable

If the device is not the first one, use a SCSI peripheral interface cable to connect it to the last device in the chain:

SCSI peripheral interface cable

Connecting Additional Equipment

IMPORTANT

The total length of the cables in a SCSI chain should not exceed 6 meters (20 feet). SCSI cables must have a 110-ohm impedance. For best results, use SCSI cables manufactured by Apple Computer.

m Make sure that the last (or only) device in the SCSI chain has a terminator.

Make sure that no other external SCSI device has a terminator. To ensure accurate transmission of information, a terminator must be at

each end of a SCSI chain. Your internal hard disk, which is the first device in the chain, has a built-in terminator.

Some external SCSI devices from manufacturers other than Apple have built-in terminators. (Check the information that came with the device.) If the device at the end of the SCSI chain does not have a built-in termi nator, you need to attach an external terminator.

SCSI terminator

If your SCSI device has a built-in terminator, you may choose to use it as your first or last device in the chain, or you may have your Apple-authorized service provider remove any extra built-in terminators. You can attach or remove external terminators yourself.

Chapter 3

Connecting a SCSI device

Use th e se general instructions in conjunction with the instructions that came with your SCSI device:

1 Turn off your Macintosh. 2Make sure the SCSI device is switched off.

WARNING

Do not connect or disconnect any device while the device or your Macintosh is turned on. Doing so could damage the device, your computer, or both.

3 Use a SCSI cable to connect the device either to the computer’s SCSI port or to the last

SCSI device already in the chain.

4 Turn on all devices in your SCSI chain.

IMPORTANT

Always turn on any external SCSI devices connected to your Macintosh before turning on the computer itself. Otherwise, your computer won’t b e able to recognize that the SCSI devices are connected to it and your computer may not be able to start.

5 Install any necessary device drivers (software that makes a device work with your

computer).

Drivers needed for a SCSI device usually come on a floppy disk with the device. (If no drivers come with the device, contact the device manufacturer.)

Note: If you experience problems after connecting a SCSI device, see the troubleshooting information in Chapter 6 for possible solutions.

Expanding memory

The random-access memory (RAM) in your computer can be expanded. Installing additional RAM adds more memory chips to your computer and expands its capabilities. The Tech ni c a l In fo rm a t i o n booklet that came with your computer describes how additional memory can be installed in your Power Macintosh.

Connecting Additional Equipment

Memory for your computer is provided in packages called Dual Inline Memory Modules (DIMMs). Adding dynamic random-access memory (DRAM) DIMMs increases your computer’s memory. The DIMMs must be the correct type for your computer, and can be installed one-at-a-time. For best perfor mance, however, the DIMMs should be installed in pairs of the same size into paired slots in your computer. Installing a cache DIMM can also increase your computer’s performance. The memory used to display images on the screen (called video RAM, or VRAM) can also be expanded by installing DIMMs.

WARNING

the Technical Information booklet that came with your computer, Apple Computer recommends that you have an Apple-certified technician install additional DRAM, VRAM, or cache DIMMs. Consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for service. If you install additional DIMMs yourself, you risk damaging your equipment and this damage is not covered by the limited warranty on your computer. See an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

It is very important that the DIMMs be correctly installed in your Power Macintosh, because incorrect installation can result in errors, unpredictable results, and damage to your equipment and data.

Installing internal drives

Your Macintosh can hold up to four internal storage devices. Possible configurations could include a floppy disk drive, a CD-ROM drive, a nd two hard disk drives (several capacities are available) or a CD-ROM drive, a floppy disk drive, a removable cartridge drive, a nd a digital audio tape (DAT) drive. Depending on the configuration you purchased, these drives may already be installed. If you want to add an internal drive to your Macintosh, see your Apple-authorized dealer. For more information about internal drives, see the Tec h n i c a l In for m at i o n booklet that came with your Macintosh.

Although instructions for installing DIMMs are provided in

Chapter 3

Connectin g network cables

Your Macintosh can be connected to a high-speed Ethern et n etwork via an AAUI Ethernet connector or a high-speed 10BASE-T Ethernet connector. You can also connect to a LocalTalk network.

It is possible to be physically connected to more than one kind of network at the same time, but you can use only one of your connections at one time. If both 10BASE-T and AAUI networks are connected, your Macintosh automatically uses the 10BASE-T connection. If 10BASE-T and LocalTalk are connected, your Macintosh uses the 10BASE-T connection. If AAUI and LocalTalk are connected, your Macintosh uses the AAUI connection.

About Macintosh networking

Your Power Macintosh can connect to a network that consists of as few as two computers or as many as thousands or even millions of computers and other devices. The network allows you and the other people connected to it to share information, access remote services, and share computing resources such as printers and modems.

A network extends the features of your Macintosh by extending your reach to the services and resources provided on the network. For example, your computer alone lets you store, retrieve, and modify information on floppy disks, hard disks, and CD-ROM discs. On a network, however, you can also store and retrieve information on the hard disks and CD-ROM discs of other computers, access information that other people have stored for you, or use mail or other network services.

Your computer comes equipped with two built-in network interfaces: LocalTalk and Ethernet. You can also purchase additional Peripheral Component Interconnect (PCI) cards for alternative networks such as TokenRing, ISDN, or FDDI.

To connect your computer to a network you need to do two things: connect your computer to the network using the appropriate cable, and set up your network configuration in the AppleTalk control panel, the TCP/IP control panel, or both.

Connecting Additional Equipment

To set up your network configuration, open the AppleTal k control panel to choose the physical network interface you are using. (The AppleTalk control panel also contains zone information—a default zone is chosen for you.) If you plan to use TCP/IP on your Power Macintosh, you also need to choose settings in the TCP/IP control panel. You can set up your connection in two ways: manually, by entering a static Internet address, or automatically by using a network service to connect with a dynamic Internet address. To learn more about setting up network configurations, see the information on networking in Macintosh Guide, available in the Guide (h) menu.

If you’re using a static Internet address, you’ll need the following information before configuring your system (your network administrator or Internet access provider can provide this information):

Internet (IP) address:

m m

Domain name and domain name server address:

for example, 192.3.232.55

A domain connects an Inter net address to a name for your site, for example, acme.com. Enter your Domain name or type a period (.).

Gateway address:

This address provides the path the information will take

through the network at your site to reach the Internet.

Subnet mask:

A subnet mask further defines the location of your machine. You don’t need to change the default unless instructed to do so by your network administrator.

If you’re using a server on the network that will be issuing you an Intern et address using a technique called bootstrapping, then you need to decide what protocol you will use: BOOTP (BOOTstrap Protocol), or DHCP (Dynamic Host Configuration Protocol). Your n etwork administrator will tell you which to choose.

If you see an error message after configuring your AppleTalk and TCP/IP control panels, such as, “Unable to locate host,” or “Could not create a socke t,” this co u ld indicate a problem in the TCP/IP configuration. Contact your network administrator for additional assistance.

Chapter 3

Read this chapter for information on

installing and working with application

programs on your computer.

Installing and Using Application Programs

Installing application programs

Your computer has several application programs already installed, as well as some programs that need to be installed before you can use them. The programs that come with your computer include

m AppleScript, which allows you to automate any actions you perform

repeatedly on your Macintosh

m Drive Setup, which enables you to initialize, test, and update hard disks and

other storage media. Drive Setup lets you partition very large disks (up to 2 terabytes).

m PowerTalk, which provides built-in mail and collaboration services m text-to-speech software that allows your Macintosh to speak typed text in

compatible applications such as SimpleText

m Speakable Items, speech recognition software that lets you give spoken

commands to the computer and have the computer respond by executing the co mma nds and giving computer-voice feedback

Yo u’ll find these and other programs in the Apple Extras folder on your hard disk. (Drive Setup is in the Utilities folder.) To find out if a program needs to be installed, look inside the program’s folder for an icon labeled Installer. If you find an Installer icon and want to use that program, double-click the Installer and follow the instructions on the screen.

If you have questions about installing and using an application program, refer to Ma cintosh Guide, available in the Guide (h) menu and the Read Me files for the program. (Read Me files are text files that contain additional information about application programs. They are usually found inside the program’s folder.)

IMPORTANT

If your computer did not come with a CD-ROM drive and you did not get the CD-ROM disc that contains system software, be sure to make a backup copy of the programs in the Apple Extras folder. Backup copies allow you to restore your software if anything should go wrong. It is a good idea to always make backup copies of application programs and other software.

Yo u’ ll probably want to buy and install additional programs. See the manuals you receive with your programs for instructions on installing and using them.

In most cases, you’ll install an application program on your internal hard disk from a CD-ROM disc that contains the program. The illustration shows how to insert a CD-ROM disc into your computer’s CD-ROM drive, the disc lying flat with the label side up.

For instructions on how to eject CD-ROM discs, see “Ejecting a CD-ROM Disc” in Chapter 5. Some application programs come on floppy disks. See the “Disks” topic of Macintosh Guide, available in the Guide (h) menu, for information on inserting and ejecting floppy disks.

Chapter 4

To use your programs most effectively, follow these guidelines: m To avoid installation problems, turn off virus protection programs and use

Apple Extensions Manager to turn off system extensions (except for Macintosh Easy Open) before you install any software. To start Apple Extensions Manager, restart your computer while holding down the Space bar. Use Apple Extensions Manager to turn off all system extensions except Macintosh Easy Open (this extension is needed to rebuild the desktop correctly). To turn extensions back on, use Apple Extensions Manager to turn them on, then restart your computer.

m Put only one copy of each program on your hard disk. Having more than

one copy can cause errors.

m Whenever you copy a program disk to your hard disk, be careful not to

copy a System Folder. Always check to see what you’ve copied, and drag any extra System Folders to the Trash.

m If a program malfunctions consistently, try installing a fresh copy. If that

doesn’t help, find out from the software ma nufacturer whether your version of the program is compatible with the hardware and system software you’ re using.

Working with several programs at a time

You can open as many application programs and desk accessories as your computer’s memory allows.

All open programs are listed in the Application menu at the right end of the menu bar. The name of the active program (the one you’re using right now) has a checkmark next to it, and its icon appears in the menu bar.

The Finder icon

Commands to hide or display open windows

A checkmark

indicates the

active program.

Open programs

Installing and Using Application Programs

Finding out which programs are open

If you have several programs and windows open, you can find out which program is active and which other programs are open by pulling down the Application menu.

Switching programs

You can switch to another open program or desk accessory by choosing its name from the Application menu.

If a program’s icon is dimmed in the menu, that means its windows are hidden. Choosing the program from the Application menu displays its windows.

You can also switch to another program by clicking in a window that belongs to an op en program or by double-clicking a program icon (or the icon of a document that was created with the program).

Hiding and showing windows on the desktop

You can hide all windows except those of the active program by choosing Hide Others from the Application menu.

The other programs remain open even though their windows are hidden. When you switch to another program, its windows become visible again.

If you want to see all the open windows, choose Show All from the Application menu.

Chapter 4

Backing up your files

Making backup copies of important files is good protection against possible damage to the originals.

m You can back up files stored on your hard disk by copying them to

floppy disks.

m You can back up an entire floppy disk by copying it to another floppy disk

of the same capacity or larger, or by copying it to a hard disk.

m You can use a commercial backup program to copy new and changed files

from a hard disk to another hard disk, to a tape drive, or to a series of floppy disks.

m If your computer is on a network, you may be able to back up files by

copyi ng t hem to a shared disk on the network.

Using Power Macintosh application progr am s

Your Power Macintosh is compatible with most application programs intended for use with Macintosh computers. But certain programs are designed especially for Power Macintosh computers. (These are sometimes called “native” applications.) You’ll find that these programs take best advantage of your computer’s speed.

Special me mory requirements

Some Power Macintosh programs may be slightly larger than other programs and may take up more memory. If you find that you are running out of memory when you use your Power Macintosh programs, you can use space on your computer’s hard disk as additional memory (called “virtual memory”). For instructions on how to use hard disk space as memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.

You can also add more memory to your computer, as described in “Expanding Memory” in Chapter 3.

Installing and Using Application Programs

Shared libraries

Power Macintosh programs use special files called shared libraries. These files help Power Macintosh programs to run more efficiently, and can be used by more than one Power Macintosh program simultaneously. Any necessary shared libraries are installed automatically in the System Folder when you install Power Macintosh programs.

If a Power Macintosh program requires a shared library and there is not enough memory available for the shared library, you’ll see a message that the program could not be opened because of insufficient system memory. If this happ ens, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu, for instructions on increasing available memory.

If a required shared library is missing, you’ll see a message that the program could not be opened because the shared library could not be found. If this happens, follow the directions that came with your program to reinstall the program. If the shared library is still missing, contact the program’s manufacturer for assistance.

Chapter 4

Read this chapter for information on

using the internal CD-ROM drive,

if your computer has one.

Using the Optional CD-ROM Drive

Read this chapter for information on using the optional internal CD-ROM (Compact Disc Read-Only Memory) drive, if your computer has one. (CD-ROM drives are also sometimes called CD-ROM players.) Refer to Appendix A, “Health, Safety, and Maintenance Tips,” for information on the proper handling of CD-ROM discs.

Your internal CD-ROM drive works with CD-ROM discs, standard audio compact discs (CDs), and single-session or multisession Photo CDs. Your CD-ROM drive provides access to large amounts of information. However, you cannot save information on CD-ROM discs. ROM stands for read-only memory, meaning that the player cannot “write” information onto CD-ROM discs.

A wide selection of CD-ROM discs is available for entertainment, education, and business. A typical disc can hold over 650 megabytes (MB) of information—the equivalent of 270,000 pages of text, up to 8 hours of speech or music (depending on the sound quality), hundreds of highresolution images, or any combination of text, sound, and graphics.

Inserting a CD-ROM disc

Follow these instructions to insert a CD-ROM disc into your CD-ROM drive. Then follow the instructions provided with your disc, as well as the instructions in this manual.

1 Start up your Macintosh computer, if it’s not already on. 2Press the Open/Close button to open the tray of the CD-ROM drive.

The tray opens.

3Place a CD-ROM disc in the tray, with the disc label facing up.

Make sure the disc is lying flat and centered in the tray. If you are using a small (8 cm) disc, make sure it is centered within the inside ring on the tray.

Open/Close button

4Push the tray in, or press the Open/Close button, to close the tray.

In a few moments, an icon for the CD-ROM disc appears on your screen.

Chapter 5

Ejecting a CD-ROM disc

Foll o w the se instructions to open the tray and eject a CD-ROM disc from your computer.

IMPORTANT

You may not be able to eject a disc if it is being shared. To turn

off file sharing, use the Sharing Setup control panel.

1 Open the tray.

There are several ways to open the tray of your CD-ROM drive.

If a CD-ROM disc icon appears on your screen:

m Select the disc icon on your screen and drag the icon to the Trash. m Click the disc icon, then choose the Put Away command in the File menu. m While the AppleCD Audio Player window is active, choose Eject CD from

the File menu, or simultaneously press the x and E keys. (AppleCD Audio Player is a program that allows you to control your CD-ROM drive and is available i n the Apple [K]menu.)

If no CD-ROM disc icon appears on your screen:

m Press the Open/Close button for your CD-ROM drive.

2Take the CD-ROM disc out of the tray.

Store your disc in a safe place, away from heat, dust, and moisture.

3Push the tray in, or press the Open/Close button, to close the tray.

To avoid possible damage to the tray or the CD-ROM drive, keep the tray closed when you are not using it.

Using the Optional CD-ROM Drive

Playing audio CDs

With your CD-ROM drive and your computer’s built-in speaker, you can play audio compact discs (CDs) or audio tracks on CD-ROM discs. You can also attach headphones or speakers to the computer to listen to audio CDs and audio tracks. See Chapter 3, “Connecting Additional Equipment,” for information on connecting sound equipment to your computer.

Note that you may need to set control panel options in order to play audio CD-ROM discs. Refer to the “Sound” topic of Macintosh Guide, available in the Guide (h) menu.

To s tar t, stop, and otherwise control audio discs, use the AppleCD Audio Player program, available in the Apple (K) menu. Your audio CD software will only play tracks that contain audio information. You can listen to an audio CD or audio tracks in the background while you do other work on your computer. For more information about playing audio CDs, see the “CD-ROM Discs” topic of Macintosh Guide, available in the Guide (h) menu.

Chapter 5

Working with Photo CDs

You can use your CD-ROM drive to open Photo CD images stored on Photo CDs. A Photo CD image is a digitized version of a standard photograph that you can open and view on your computer screen.

You can do many things with the images on your Photo CDs:

m Open and view the images individually on your computer screen. m View the images on your computer screen in a series, as you would view

a slide presentation.

m Copy and save the images, print them, paste them into word-processing

documents or other documents that accept graphics, and edit them with a graphics application program.

Photo CD images are an excellent source of graphics for desktop publishing, multimedia presentations, business documents, and professional-quality graphic design. For more information on working with Photo CD images, see the “CD-ROM Discs” topic of Macintosh Guide, available i n the Guide (h) menu.

Using the Optional CD-ROM Drive

Sharing a CD-ROM disc over a network

You can share a CD-ROM disc using your computer’s file-sharing feature. If the disc has audio portions, you will be able to hear the audio yourself, but other people on the network will not. Likewise, you cannot hear the audio portions of discs you access over a network.

For further information about file sharing, see the information on sharing files in Macintosh Guide, available in the Guide (h) menu.

problems using your computer.

Troubleshooti ng

Whe n you have questions

If you want to know how to do a particular task with your computer, refer to Macintosh Guide in the Guide (h) menu. For instructions on using Macintosh Guide, see “Getting Help,” Chapter 2 of this manual.

If you have trouble

While you’re using your computer, you may occasionally see a bomb icon or an error message, or the pointer (8) may “freeze” on the screen.

If you have trouble with your computer, take a few minutes to read the information in this chapter. If your problem is related to a particular procedure, you should also look for information on that procedure in Macintosh Guide, available in the Guide (h) menu. For additional troubleshooting information and a list of common questions relating to your system software, see the “Troubleshooting” topic of Macintosh Guide.

If you are unable to access Macintosh Guide (for example, if your screen is “frozen”), refer to this chapter to see if you can resolve the problem.

WARNING

If you have a problem with your computer and nothing presented in this chapter solves it, consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for assistance. If you attempt to repair the computer yourself, any damage you may cause to the computer will not be covered by the limited warranty on your computer. Contact an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

Take your time

When you see an error message, you don’t have to take action immediately. The message stays on the screen until you click the OK button (or Restart) or turn off the computer.

To h elp diagnose and correct the problem, gather as much information on the situation as you can. Then follow the instructions in the next section, “Start Over.”

m Make a note of exactly what you were doing when the problem occurred.

Write down the message on the screen and its ID number (if any). Also list the programs you were using and the names of any items you know have been added to the System Folder since the system software was installed. This information will help a service person diagnose the problem. (It is helpful to keep a printed copy of the items in your System Folder. For instructions on printing the contents of a folder, see the information on printing in Macintosh Guide, available in the Guide [h] menu.)

m Check the screen for any clues. Is a menu selected? What programs and

document icons are open? Note anything else that seems relevant.

m If you were typing text and were not able to save it before the problem

occurred, you can write down the parts of the text still visible on the screen so that some of your work will be easy to replace.

Chapter 6

m Ask other Macintosh users about the problem you’re having; they may have

a solution for it.

If you need repair service, consult the service and support information that came with your computer for instructions on how to contact an Appleauthorized service provider or Apple for assistance.

If you know that the problem is with a particular application program, contact the manufacturer of that software for assistance.

Start over

Often you can eliminate a problem simply by clearing the computer’s memory and starting over.

If you can, save any open documents before restarting the Macintosh. If your system is frozen and do es not respond to anything you do, or if you have a “bomb” message on the screen, saving may not be possible. You can try pressing x-Option-Esc to quit the program in use when the problem occurred; if this works, you can then save the documents open in other programs before restarting. (Be sure to restart the computer immediately after you save your documents—quitting a program using x-Option-Esc may leave corrupted data in the computer’s memory. This corr upted data is erased when you restart the computer.)

To restart your Macintosh, try the following solutions:

If you can, choose Restart from the Special menu or from the dialog box that’s on the

screen.

Dialog boxes contain messages from the computer. If something goes wrong, a message may appear on the screen, asking you to restart the computer.

If you can’t choose Restart, press the Power key on the keyboard.

Select Restart from the dialog box that appears.

If the Power key on the keyboard doesn’t work, hold down the while you press the Power key on the keyboard (marked with a triangle).

and Control keys

This key combination restarts the computer. (Use this key combination only when you can’t choose Restart from the Special menu.)

Troubleshooting

Turn off your computer with the power button on the front panel of the computer, wait at least 10 seconds, and then turn it on again.

If the computer does not turn off, try pressing and holding down the power button for 3 to 4 seconds.

If the power button doesn’t turn off the computer, unplug your Macintosh.

If you suspect that the problem is with other equipment, such as a printer or an external hard disk that’s attached to your computer, turn that equipment off and restart the Macintosh.

Rebuild your desktop regularly

A process known as “rebuilding the desktop” helps your Macintosh keep track of data on your startup disks. Although you usually use the hard disk in your computer as a startup disk, you can also start up from any other disk that has system software installed. It’s a good idea to rebuild the desktop of your startup disks once a month or so.

To rebuild the desktop of a startup disk, follow these steps:

1While holding down the Space bar, restart your computer.

Do not release the Space bar until you see the Extensions Manager control panel.

2 Use the Extensions Manager control panel to turn off all extensions except Macintosh

Easy Open.

3While holding down the xand Option keys, close the Extensions Manager control panel.

The desktop is rebuilt.

4 Open the Extensions Manager control panel again and turn back on all the extensions

you turned off.

Chapter 6

Solut ions to common p roblems

This section contains descriptions of problems you could experience with your computer. Some problems may be caused by your CD-ROM drive, so if you don’t find your problem here, be sure to check the section “Solutions to CD-ROM Problems” later in this chapter.

The computer is turned on but the screen is dark.

One of the following is probably the cause: m The computer is in sleep mode.

Press a key on the keyboard.

m You have a screen saver program that darkens the screen when the

computer has not been used for a certain period. Press a key or move the mouse to turn off the screen saver.

m The monitor’s brightness control (¤) is not adjusted properly.

Check the monitor’s brightness control and turn it up if necessary.

m The Macintosh or the monitor is not getting power.

If you have a separate monitor, check that the monitor is plugged in and turned on a nd that the monitor cable is firmly connected to both the computer and the monitor.

Check that the computer’s power cord is firmly connected to the computer and plugged into a grounded electrical outlet and that the outlet has power.

If you have more than one monitor, a nd only one is dark, check that it is set up correctly in the Monitors control panel. For information on using more than one monitor, see the “Monitors” topic of Macintosh Guide, available i n the Guide (h) menu.

m If none of these steps solves the problem, you may need to reset your

computer’s parameter RAM (PRAM). Reset PRAM by turning off the computer and disconnecting all external SCSI devices. Next, restart the Macintosh while holding down the key combination x-Option-p-r. Wait for the second startup chime, then release the keys. (Note that the “caps lock” key must be in the up position. This procedure won’t work with the upper case “P” and “R” keys.)

Troubleshooting

The computer’s clock keeps time inaccurately.

Your computer has a clock that runs continuously. When the computer is turned off, a battery keeps the clock running. If your clock begins to keep time inaccurately, have an Apple-authorized service provider replace the battery. Consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for assistance.

When you start up, a disk icon with a blinking question mark appears in the middle of the screen.

This icon indicates that your Macintosh cannot find the system software it needs to start up. One of the following is probably the cause:

m Your computer may be having a problem recognizing external equipment

that uses the Small Computer System Interface (SCSI). Shut down the computer, turn off all external SCSI equipment, and

disconnect the first SCSI device in the chain from your computer’s SCSI port. Th en restart the computer. If the computer starts up after you disconnect your SCSI equipment, refer to the manuals that came with the equipment for information on the proper way to connect SCSI equipment and assign SCSI ID numbers.

If you have a printer connected to your computer’s SCSI port, make sure your printer is not supposed to be connected to the printer port instead. Check the manuals that came with your printer for information on how to connect it properly.

Chapter 6

m System sof tware may not be installed on the startup hard disk, the system

software may be damaged, or the hard disk may not be working properly. Star t up your computer using the Disk Tools floppy disk or (if you have a

built-in CD-ROM drive) with the CD-ROM disc that contains system software. (For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this chapter.) Then follow the instructions in “Repairing a Damaged Disk” later in this chapter to test your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing or Reinstalling System Software” later in this chapter to reinstall system software on your startup hard disk.

When you try to start up from a floppy disk, a disk icon with an X appears in the middle of the screen, and the floppy disk is ejected.

This icon indicates that the floppy disk you tried to start up from is not a startup disk.

Wait a few seconds. The computer should start up from its internal hard disk. Make sure you insert floppy disks only after the computer has begun starting up.

Troubleshooting

A “sad Macintosh” icon appears, and the computer won’t start up.

This icon indicates that your Macintosh cannot start up because of a problem with the system software or the computer hardware.

Eject any floppy disks by turning off the computer and then holding down the mouse button while you turn the computer on again. Try starting up with the Disk Tools floppy disk or (if you have a built-in CD-ROM drive) with the CD-ROM disc that contains system software. (For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this chapter.) If the “sad Macintosh” icon appears again, consult the service and support information that came with your computer for information on contacting an Apple-authorized service provider or Apple for assistance.

The hard disk icon does not appear on the desktop.

If you don’t see a hard disk icon on the desktop, try the following: m Use th e Drive Setup program to make the disk available. Drive Setup is

locat ed in the Apple Extras folder. For instructions, start Drive Setup, then choose Drive Setup Guide from the Guide (h) menu.

m If the hard disk is internal, shut down your computer, wait at least 10

seconds, and then turn it on again.

m If the hard disk is external, make sure that it is turned on and that its cable

is connected firmly; then restart the Macintosh.

m Check the ID numbers of all SCSI equipment connected to your computer.

No two SCSI devices on the same SCSI chain can have the same ID number. In addition, there are special requirements for assigning SCSI ID numbers that don’t conflict with your computer or its internal storage devices. See Chapter 3 and the manuals that came with your SCSI equipment for information on setting SCSI ID numbers.

Chapter 6

m If the hard disk is your startup disk, start your computer using the Disk

Tool s floppy disk or (if you have a built-in CD-ROM drive) with the

CD-ROM disc that contains system software. (For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this chapter.) Then follow the instructions in “Repairing a Damaged Disk” later in this chapter to test your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing or Reinstalling System Software” later in this chapter to reinstall system software on your startup hard disk.

Icons do not appear correctly on your screen.

You need to rebuild the desktop—a process that helps your Macintosh keep track of files and folders on your hard disk. For instructions, see “Rebuild Your Desktop Regularly” in the section “If You Have Trouble” earlier in this chapter.

Your Macintosh can’t read a floppy disk.

If you see a message that a floppy disk is unreadable, try one of the following: m If the disk has never been used, you may simply need to initialize it. For

instructions, see the “Disks” topic of Macintosh Guide, available in the Guide (h) menu.

m The disk may be damaged. See “Repairing a Damaged Disk” later in this

chapter for information on testing and repairing disks.

m If the disk is a high-density disk previously used on another computer, the

disk may have been formatted incorrectly as an 800K disk rather than as a 1440K (high-density) disk. If so, use the other computer to copy the disk’s contents onto a properly formatted disk.

m The disk may have been formatted for use on another kind of computer.

You may be able to use a program that lets you work with such disks on your Macintosh.

You can’t eject a floppy disk.

If you can’t eject a floppy disk in the usual way, try the following in order: m Hold down the x and Shift keys and press the number 1 key on your

keyboard to eject a disk in the internal disk drive.

Troubleshooting

m Tur n off the computer. If the disk isn’t ejected, then hold down the button

on your mouse or other pointing device while you turn the computer on again.

m Locate the small hole near the disk drive’s op ening, and carefully insert the

end of a large straightened paper clip into it. Push gently until the disk is ejected. Do not use excessive force.

If none of these solutions works, take the computer or disk drive to your Apple-authorized service provider to have the disk removed.

You installed a CD-ROM drive after you bought your computer and your computer won’t restart after you’ve copied software for your CD-ROM drive to the System Folder.

m If you attempt to install software for your CD-ROM drive without using the

Installer, you may not be able to restart your computer. Restart the computer while holding down the Shift key (to turn off system extensions) and then remove any CD-ROM software files you copied by dragging them to the Tras h . Reinstall the software according to the instructions that came with the drive.

If this procedure doesn’t solve the problem, restart your computer using the Disk Tools floppy disk or the CD-ROM disc containing system software that came with your computer. (For instructions on starting your computer using a floppy disk, see “Starting Up From a Floppy Disk” later in this chapter.)

Your computer won’t restart, and a CD-ROM disc is in the CD-ROM drive.

m Your computer may be trying to start up from the CD-ROM disc. Press the

Open/Close button of your CD-ROM drive to open the tray and remove the CD-ROM disc. Close the tray, then restart your computer.

Chapter 6

You can’t start an application program, or it quits unexpectedly. Or, when you try to open a program, you see a message that not enough memory is available.

One of the following is probably the cause: m The Macintosh ran out of memory.

Quit the programs that you have open and then open the program you want to use, or restart your Macintosh.

Make sure virtual memory is turned on (unless you changed the memory setting, virtual memory was already turned on for you at the factory). If it isn’t, use the Memory control panel to turn on virtual memory. For more information on virtual memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.

m The program needs more memory.

Use th e program’s Info window to give it more memory. For more information on increasing a program’s memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.

m The program is a non-Power Macintosh application program running in

emulation mode that requires a separate floating-point unit (FPU). It cannot use the built-in FPU on your computer’s microprocessor.

Check the documentation that came with the program or contact the program’s manufacturer to find out if the program requires the FPU found in a non-Power Macintosh chip. If it does, you may need to upgrade to a Power Macintosh version of the program, or install software that emulates a non-Power Macintosh FPU. (See your dealer for this software.)

m Sometimes incompatible system extensions or control panels can cause

software problems. Restart while holding down the Shift key to temporarily turn off all system extensions.

If your program works normally after you do this, use the Extensions Manager control panel to turn off individual extensions and control panels. For detailed instructions, see the “Customizing Your Computer” topic of Macintosh Guide, available in the Guide (h) menu.

If your program performs better when a particular extension or control panel is turned off, contact the software’s ma nufacturer for information or an upgrade.

Troubleshooting

A dialog box with a bomb appears.

Your system has a software problem. m Write down what you were doing when the message appeared and write

down the message.

m Restart your Macintosh. (See “Start Over” in the section “If You Have

Trouble” earlier in this chapter for instructions.) Most software problems are temporary, and restarting usually corrects the problem.

m Check the startup disk and application program you were using when the

dialog box appeared. Make sure that all programs, desk accessories, and system ex tensions you’re using are compatible with the system software. Reinstalling the system software may correct the problem.

m If the bomb only occurs in one application program, try reinstalling the

program from the original disks. If reinstalling doesn’t solve the problem, contact the manufacturer of the program.

m Sometimes incompatible system extensions or control panels can cause

system software problems. Restart while holding down the Shift key to temporarily turn off all system extensions.

If your computer works normally after you do this, use the Extensions Manager control panel to turn off individual extensions and control panels. For detailed instructions, see the “Customizing Your Computer” topic of Macintosh Guide, available in the Guide (h) menu.

If your computer performs better when a particular extension or control panel is turned off, contact the extension’s or control panel’s manufacturer for information or an upgrade.

m If the problem recurs, you may need to reinstall system software. See

“Installing or Reinstalling System Software” later in this chapter for instructions.

The pointer (8) doesn’t move when you move the mouse.

One of the following situations is probably the cause: m Your system has a software problem.

Press x-Option-Esc to quit the application program in use when the problem occurred. If this works, you can save the documents open in other programs before restarting.

Restart your Macintosh. See “Start Over” in the section “If You Have Trouble” earlier in this chapter for instructions.

Check the startup disk and program you were using when the problem occurred. Make sure that all programs, desk accessories, and system extensions you’re using are compatible with the system software. Try starting up the computer from the Disk Tools disk or the CD-ROM disc that contains system software. (For instr uctions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this chapter.) If your computer starts up nor mally, there may be an extension conflict.

If the problem recurs, you may need to reinstall system software. See “Installing or Reinstalling System Software” later in this chapter for instructions.

m The mouse is not connected properly.

Tur n the computer off using the power button on the front of the computer, che ck that the mouse and keyboard cables are connected properly, and then restart the computer.

IMPORTANT

Do not connect the mouse while the computer is turned on. You

may damage your computer. m Signals from the mouse are not reaching the computer, either because the

mouse needs cleaning or because there is something wrong with the mouse. Clean the mouse according to the instructions in Appendix A of this book. If you have another mouse or pointing device, try connecting and using it.

(Turn the computer off before connecting it.) If the new device works, there is probably something wrong with the mouse you replaced.

If none of these procedures solves the problem, consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for assistance.

Troubleshooting

Typing on the keyboard produces nothing on the screen.

One of the following is probably the cause: m Your system has a software problem.

Restart your Macintosh. For instructions, see “Start Over” in the section “If You Have Trouble” earlier in this chapter.

Check the startup disk and application program you were using when the problem occurred. Make sure that all programs, desk accessories, and system ex tensions you’re using are compatible with the system software.

If the problem recurs, try restarting the computer with system extensions turned off. (To turn system extension off, hold down the Shift key while restarting the computer.) If that doesn’t work, you may need to reinstall system softwa re. See “Installing or Reinstalling System Software” later in this cha p ter for instructions.

m The computer beeps every time you press a key.

Easy Access is probably turned on. Open Easy Access from the control panels listed under the Apple (K)menu a nd turn it off.

m You haven’t selected any text or set the insertion point (i).

Make sure the program you want to type in is the active program. Then place the pointer (8

) in the active window and click to set an inser tion

point (i) or drag to select text (if you want to replace the text with your typing).

m The keyboard is not connected properly.

Tur n off the computer using the power button on the front of the computer, then check that the keyboard cable is connected properly at both ends.

If you have a keyboard with an ADB port (marked with the ◊ icon) on each end, turn off the Macintosh using the power button and plug the keyboard cable into the other ADB port on the keyboard. (You may have to unplug the mouse to do this.) T hen restart the computer.

Chapter 6

m The keyboard is damaged.

If you have access to another keyboard, try using it instead. (Turn the computer off before connecting it.) If the new keyboard works, there is probably something wrong with the one you replaced.

You can’t open a document, or you see a message that an application program can’t be found.

m Some documents can be op ened by more than one application program.

Try starting a program that you think might be able to open the document, then choose Open from the program’s File menu to try to open the document.

m Purchase and install the correct software to use the document, or find out

if the creator of the document can convert it to a form that one of your programs can use.

m Don’t try to open the files in your System Folder. Most of the files in your

System Folder are used by your computer for internal purposes and are not intended to be opened.

m Rebuild your desktop (refer to “Rebuild Your Desktop Regularly” in the

section “If You Have Trouble” earlier in this chapter).

m If the document is from a DOS computer, use the PC Exchange control

panel to specify which Macintosh program will open the document. For information about working with DOS documents on your Macintosh, see the information about DOS in Macintosh Guide, available in the Guide (h) menu.
