Problems That Prevent You from Using Your iMac

If your iMac won’t respond or the pointer won’t move

åFirst, make sure the mouse and keyboard are connected. Unplug and then plug in the connectors and make sure they are secure. If you have a wireless keyboard or mouse, make sure the batteries are fresh.

åIf that doesnÕt work, try to force problem applications to quit. Hold down the Option and Command (x) keys and press the Esc key. If a dialog appears, select the application and click Force Quit. Then save your work in any open applications and restart your iMac to be sure the problem is entirely cleared up.

åIf you are unable to force the application to quit, press and hold the power (¨) button on the back of the iMac for a few seconds to shut down the computer.

åIf that doesnÕt work, unplug the power cord from the iMac. Then plug the power cord back in and press the power (¨) button on the iMac to turn it on.

If the problem occurs frequently when you use a particular application, check with the applicationÕs manufacturer to see if the application is compatible with your iMac.
