With Mac OS 7.6, your computer will perform better and more reliably.
You can also take advantage of new features that enhance your computer’s
networking, multimedia, printing, and other capabilities.
Follow the instructions in this chapter to install Mac OS 7.6.
System requirements
The following computers can install Mac OS 7.6:
m computers with PowerPC
m computers with 68040 microprocessors
m computers with “32-bit clean” 68030 microprocessors. All computers with
68030 microprocessors are 32-bit clean except the Macintosh SE/30,
Macintosh IIx, and the Macintosh IIcx.
In addition, to install Mac OS 7.6, a computer must have at least 8 MB of
RAM (random-access memory). If your computer has less than 16 MB of
built-in RAM, you must use virtual memory. (Mac OS 7.6 automatically turns
on virtual memory when you install it.)
™
microprocessors
If you don’t know how much RAM your computer has, choose About This
Macintosh from the Apple (K) menu. Check the number next to Built-in
Memory.

Before you begin
To install the recommended software, you need about 70 MB of free space on
your hard disk. To install all the optional components, you may need up to
120 MB of disk space; if you install just the minimum set of system software,
you may only need 40 MB. The exact amount of space needed varies for
different computer models and hard disk sizes.
To check the amount of hard disk space you have, open your hard disk icon.
Then choose By Icon or By Small Icon from the View menu and check the
number in the far-right corner of the window’s title bar. (The number has the
words “MB available” after it.)
By the way: Many application programs use your hard disk to temporarily
store information, so it's a good idea to keep at least 10 percent of your disk
space free. For best performance, you should recheck the amount of available
disk space after installing Mac OS 7.6.
Before you begin the installation, do the following:
m Turn off any virus-protection software and disk-security software you
may have.

Chapter 1
m If At Ease software is installed on your computer, turn it off before you
install Mac OS 7.6. For instructions, see the manual that came with your
At Ease software.
m If you are installing on a PowerBook, make sure your PowerBook is
plugged in and set not to go to sleep. For instructions, see the manual that
came with your computer.
WARNING
PowerTalk is not compatible with Mac OS 7.6. Installing
Mac OS 7.6 disables PowerTalk. If you use PowerTalk, see “Installing
Over PowerTalk” in Chapter 3 before continuing with the
upgrade process.
Start up from the Mac OS 7.6 disks
You should start up your computer using the system software on the CD-ROM
disc or floppy disks you received in the Mac OS 7.6 package. That way, you
can repair any problems on your hard disk and update the disk driver before
you install the software.
To start up your computer with the provided disks, follow these steps:
1Shut down your computer.
2Insert the
Mac OS 7.6
CD-ROM disc into the CD-ROM drive.
If you’re installing from floppy disks: Insert the Mac OS 7.6 Install Me First disk
into your floppy disk drive.
3Turn on your computer.
If you’re installing from a CD-ROM disc: Hold down the C key on your
keyboard until you see the screen with the smiling face. If you have a
PowerBook 1400, you’ll need to hold down the x (Command), Option, Shift,
and Delete keys instead of the C key.
You’ll know you’ve started up with the CD-ROM disc if you see the CD-ROM
disc icon at the top-right corner of the desktop, above your hard disk icon.
If you have trouble starting up from the CD-ROM disc: See “Problems During
Installation” in Chapter 3.
IMPORTANT
If you don’t have an Apple CD-ROM drive, you won’t be able to
start up from the CD, but you can still install the software from it. To ensure a
smooth installation, turn off all your non-Apple extensions and restart your
computer before beginning.
m If you are using System 7.5 or later, you can open the Extensions Manager
control panel and choose “System 7.5.x” in the Sets pop-up menu. Then
restart the computer.

m If you are using an earlier version of system software, or don’t have the
Extensions Manager, drag any non-Apple extensions out of your
Extensions folder in the System Folder, then restart the computer. (If you
don’t know where a particular extension came from, select its icon. Then
choose Get Info from the File menu. Apple extensions all have “
Computer, Inc” in the Version section of the Get Info box.)
Installing the software
Use the Install Mac OS application program to make sure you follow all the
necessary steps for installing the software.
m To open the Install Mac OS program, double-click its icon.
Next, a screen appears describing the four steps in the upgrade process.
Step 1: Read important information
Click the first button to read about the upgrade process, as well as
compatibility and troubleshooting information.
Click here.
Read the onscreen document that appears. Since the onscreen document was
written later than this book, it may contain additional information.
When you’re finished reading the document, choose Quit from the File menu
to return to the Install Mac OS screen.

Step 2: Update your hard disk driver
Hard disks with old drivers might cause problems after installing Mac OS 7.6.
Your computer might not start up, or you might not see the hard disk icons on
the desktop. To avoid these problems, it’s a good idea to update your drivers.
The disk utilities that Apple provides won’t update some disks. You can skip
step 2 if one of the following is true:
m You don’t have an Apple hard disk or you don’t have an Apple computer.
Check the instructions that came with your computer or hard disk to see if
the manufacturer includes or recommends a disk utility, and use that utility
to update the driver. Make sure to get the latest version of the utility from
the manufacturer. An old utility will not be able to update your disk with
the most current driver.
m Yo u’ve previously used a non-Apple disk utility to format your disk or
update the driver. You’ll need to use that utility again to perform the
update. Make sure to get the latest version of the utility from the
manufacturer. An old utility will not be able to update your disk with the
most current driver.
m You have a PowerBook 150 and no external Apple hard disks. PowerBook
150 internal disk drivers are built into the computer’s read-only memory
(ROM) and cannot be updated.
