To get support and contact information for the software that came with your iMac, go to www.apple.com/guide.
If the problem occurs frequently, you may need to reinstall your system software (see ÒReinstalling the Software That Came with Your iMacÓ on page 70).
If the iMac freezes during startup or you see a flashing question mark
åWait a few seconds. If your iMac doesnÕt start up after a brief wait, shut it down by pressing and holding the power (¨) button for about 5 seconds, until the iMac shuts down. Then hold down the Option key and press the power (¨) button again to start up your iMac. When your iMac starts up, click the hard disk icon, then click the right arrow.
åAfter the iMac starts up, open System Preferences and click Startup Disk. Select a local Mac OS X System folder.
åIf the problem occurs frequently, you may need to use Disk Utility (located on the Mac OS X Install Disc 1 that came with your iMac) or reinstall your system software (see ÒReinstalling the Software That Came with Your iMacÓ on page 70).
If the iMac won’t turn on or start up
åMake sure the power cord is plugged into the iMac and into a functioning power outlet.
åIf that doesnÕt work, press the power (¨) button and immediately hold down the Command (x), Option, P, and R keys until you hear the startup sound a second time.
åIf you recently installed additional memory, make sure that it is correctly installed and that it is compatible with your iMac. Check whether removing the memory you installed allows the iMac to start up (see page 60).
