Problems That Prevent You From Using Your Computer

If the computer won’t respond or the pointer won’t move

•Press Command (x)-Option-Esc to force a frozen application to quit. If a dialog appears, select the application you would like to quit and click Force Quit.

If you are working in Classic, hold down the Option and Command (x) keys and then press the Esc key.

Next, save your work in any open applications and restart the computer to be sure the problem is entirely cleared up.

•If you are unable to force the application to quit, press and hold the Power button (®) for a few seconds to shut down the computer.

•If the computer still doesn’t respond, try to restart it by simultaneously pressing the Command (x) and Control keys on your keyboard and the Power button (®).

If the problem occurs frequently, choose Help > Mac Help from the menu bar at the top of the screen. Search for the word “freeze” to see help for instances when the computer freezes or doesn’t respond.

If the problem occurs only when you use a particular program, check with the program’s manufacturer to see if it is compatible with your computer. If you know an application is compatible, you may need to reinstall your computer’s system software or, if you’re using Classic, you may need to check for incompatible system extensions. See the next topic for instructions.

If the computer freezes during startup or you see a flashing question mark

Try using Disk Utility to repair your hard disk.

1Insert the first software install and restore disc into your computer. Then restart your computer and hold down the C key as it starts up.

2Choose Installer > Open Disk Utility. When Disk Utility opens, follow the instructions in the First Aid pane to see if the utility can repair your disk.

If using Disk Utility doesn’t work, you may need to reinstall your computer’s system software. For instructions, see page 63.

If you are using the Classic environment in Mac OS X, you might have an incompatible extension. (Mac OS X does not use system extensions.)

Try turning off your system extensions to see if that solves the problem. To turn off extensions in Classic, open System Preferences, click Classic, click the Advanced tab, and choose Turn Off Extensions from the pop-up menu. Click Restart Classic.

If turning off extensions appears to solve the problem, you may need to identify and eliminate or reinstall the extension that is causing the problem. Open the Extensions Manager control panel and turn off the extensions you suspect are causing the problem. Then restart Classic with the extensions turned on again.
