Problems That Prevent You From Using Your Computer
If the computer won’t respond or the pointer won’t move
 First, make sure the mouse and keyboard are connected. Unplug and then plug in
the connectors and make sure they are secure.
 If that doesn’t work, try to force problem applications to quit. Hold down the Option
and Command (x) keys and then press the Esc key. If a dialog appears, select the
frozen application and click Force Quit. Then 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
(®) on the back of the computer for five seconds to shut down the computer.
 If that doesn’t work, unplug the power cord from the computer. Then plug the power
cord back in and press the power button (®) on the computer to turn it on.
If the problem occurs frequently when you use a particular application, check with the
application’s manufacturer to see if it is compatible with your computer.
For support and contact information about the software that came with your
computer, go to www.apple.com/guide.
If the problem occurs frequently, try reinstalling your system software (see “Reinstalling
the Software That Came With Your Computer” on page 58).
