The screen freezes.

å Force the frozen application to quit. Choose Apple ( ) > Force Quit and select the application.

åIf that doesnÕt work, force the computer to restart by pressing the power button (¨) for 5 or 6 seconds until your Mac Pro shuts down. Press the power button (¨) again to start up your Mac Pro.

The light on the front of the display is flashing.

On some Apple flat panel displays, the power light displays a series of short flashes when an error is detected.

åIf you see a repeating sequence of three short flashes, the display is detecting input in the wrong video format. Make sure your display is compatible with your graphics card and that youÕve installed the correct display software, if your display came with installation software.

åIf you see a sequence of two short flashes and a long flash, the display is detecting a problem with a backlighting lamp. Contact an Apple Authorized Reseller or Apple Authorized Service Provider.
