6 Troubleshooting
If you have a problem while working with your computer, here are some things you can try
right away.
Note: If you have problems in the Classic environment, troubleshoot them as you would in
Mac OS 9, not Mac OS X.
If the computer won’t respond or the pointer won’t move:
First, make sure the mouse and keyboard are connected.
m Unplug and then plug in the connectors and make sure they are firmly seated.
Then try to cancel what the computer is doing.
m Press the Command (x) and Q keys at the same time to try to quit the current application.
m Press the Command (x) and period keys at the same time and, if a dialog box appears,
click Cancel.
m In Mac OS X, choose Force Quit from the Apple (K) menu and select the application.
Restart the computer by choosing Restart from the Apple (K) menu to be sure the
problem is entirely cleared up. You can also press the Esc, Option, and Command (x)
keys at the same time.
m In Mac OS 9, hold down the Esc, Option, and Command (x) keys to force the application
to quit. Restart the computer by choosing Restart from the Special menu to be sure the
problem is entirely cleared up.
m If that doesn’t work, hold down the power button on the front of the computer for
five seconds. After the computer turns off, press the button again to turn it on.
m If all else fails, unplug the power cord to turn the computer off, then replug the power
cord and use the front panel power button to restart the computer.
m 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.
