Problems Using Your Computer 31
m Try starting up your computer from the system software CD that came with your
computer. Insert the CD and restart while holding down the C key. (See Chapter 3,
“Starting Up From a CD,” on page 45.) If only the hard disk icon appears on the desktop,
then there may be a hardware problem with your CD-ROM drive. If the CD-ROM disc icon
appears above the hard disk icon, reinstall your CD-ROM software. The easiest way to do
this is by reinstalling your system software. See Chapter 5, “Reinstalling Your Computer’s
Software,” on page 53.
m The disc may use a format that the Macintosh cannot recognize. Ask the disc’s
manufacturer for a disc that a Macintosh can recognize.
Disc is vibrating in the drive.
m Make sure the disc is centered in the tray.
m Some CD-ROM disc labels have artwork that is noticeably thicker on one side than the
other and can cause the disc’s weight to be slightly off-center. This uneven distribution of
weight coupled with the high rotation speed of your CD-ROM drive can cause some discs
to wobble in the drive and make your computer vibrate. The vibration does not damage
the CD-ROM disc or the computer and affects very few CD-ROM discs. If you can feel or
hear that the CD-ROM disc is vibrating in the computer, you don’t need to do anything
special; continue to use the CD-ROM disc as you normally would.
Note: If you use a CD-ROM disc with a removable (sticky) label, remove the label before
inserting the disc.
Tray won’t open.
If a CD-ROM disc icon appears on your screen:
m Select the disc icon and choose Put Away from the File menu, or drag the icon to the
Trash.
Note: You won’t lose information on the CD by dragging its icon to the Trash.
If the AppleCD Audio Player is active, choose Eject CD from the File menu or click the
eject button in the AppleCD Audio Player controller.
If you see a message that a disc can’t be put away because it is being shared, turn file
sharing off in the File Sharing control panel in the Control Panels folder, available in the
Apple (
K) menu.
If no CD-ROM disc icon appears on your screen:
m Restart your computer. Immediately after you hear the startup sound, press the Open
button on your CD-ROM drive.
m The signal to open the tray may not be reaching the computer. Manually remove the disc,
as described in the online documentation that came with your computer.
If neither of these suggestions works, your CD-ROM drive may be damaged. Contact an
Apple-authorized service provider or Apple for further assistance.
