Problems Working With Computer Programs or the Mac OS
If software difficulties (such as a software error message on your screen) don’t allow you to
use standard methods of quitting a program or restarting your computer, you can try using
these special key combinations.
The reset key combination immediately turns off the computer. Then the sleep indicator
light glows briefly while the computer goes through the reset process. After the sleep
indicator light turns off, wait a few seconds and then press the Power button again to start up
the computer.
For more information on solving problems, see the troubleshooting manual that came with
your computer.
To do this... ...press this key combination
Force a program to quit
x-Option-Esc
Force the computer to restart
x-Control–Power button
Force the computer to reset Shift- Fn-Control–Power button
Important Only force the computer to reset if the other two key combinations are
unsuccessful at solving your problem. When you force a reset, your computer’s default
(original) settings will be restored. You may need to reconfigure settings for power
management, memory, trackpad, TCP/IP, and AppleTalk if you reset the computer.
