2010-09-14
General Troubleshooting
Update System Software & Firmware
Important: Ensure the correct version Mac OS X and latest software and rmware updates have
been applied before you begin troubleshooting. Computers sometimes exhibit symptoms that
indicate the wrong Mac OS X system software is installed.
Firmware is the name given to software that is written into memory circuits such as ash
memory, that will hold the software code indenitely, even when power is removed from the
hardware. Firmware on Intel Mac computers is designed to be updated if necessary by running
the Mac OS X Software Update check (available in the Apple () menu) while computer is
connected to the Internet. For more information about rmware updates, refer to:
kBase # HT1557: About rmware updates for Intel-based Macs
Troubleshooting Theory
For general information on troubleshooting theory, go to GSX and nd the Service Training
course menu link. From there you can access the Troubleshooting Theory self-paced course.
Hardware vs. Software
For information on how to isolate a hardware issue from a software issue, refer to:
kBase #TS1388: Isolating issues in Mac OS X
For information on how to troubleshoot a software issue, refer to:
kBase #HT1199: Mac OS X: How to troubleshoot a software issue
kBase #TS1394: Mac OS X: Troubleshooting installation and software updates
kBase #HT2956: Troubleshooting Mac OS X installation from CD or DVD
Temperature Concerns
The normal operating temperature of this computer is well within national and international
safety standards. Nevertheless, customers may be concerned about generated heat. To prevent
an unneeded repair, you can compare a customer’s computer to a similar running model, if

computer as well as the types of devices and drives connected. To reset PRAM:
1. If computer is on, turn it o by choosing Shut Down from Apple () menu.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to
hold these keys down simultaneously in Step 4.
Note: If keyboard does not have an Option key, use Alt key instead.
3. Press power button.
4. Immediately press and hold Command-Option-P-R keys.
Important: You must press this key combination before the gray screen appears.
5. Hold down keys until computer restarts, and you hear startup chime a second time.
6. Release keys.

Clamshell Service Diagnostic (CSD)
Clamshell Service Diagnostic (CSD) is a diagnostic tool that checks Apple’s latest portable
computers for the presence of AirPort, Bluetooth, LCD and Ambient Light Sensor (ALS) to assist
you in quickly making a failure determination.
Troubleshooting benets of using CSD include:
• Quick way (less than 1 minute) to determine whether clamshell-related modules (AirPort,
Bluetooth, LCD and ALS) are electrically connected without taking apart the system.
• Results of CSD can help pinpoint if any clamshell cables may need to be reseated to logic
board.
• Diagnostic results can help isolate a video or wireless issue to either clamshell or logic
board, to avoid unnecessary replacements of these components.
In the MacBook Pro (13-inch), CSD checks for the presence of the computer’s:
• AirPort
• Bluetooth
• LCD
• Ambient Light Sensor (ALS)
CSD does not check for the presence of the computer’s:
• iSight camera
• externally connected hardware components (such as USB or FireWire devices)
CSD does not check for issues with the OS X or other software-related problems such as
application or extension conicts.
For more information, and to download CSD, refer to:
