iMac DVD Update 1.0

iMac DVD Update 1.0 places new firmware on the DVD-ROM shipped in iMac DV and iMac DV Special Edition computers. This update improves the ability of iMac DV models to read certain CD-ROM discs and to determine if a disc is unreadable.

Certain CD-ROM discs are created in a way that makes them difficult to read. Some iMac DV and iMac DV Special Edition computers will try to read these discs for a very long time. During this time, the iMac will not respond to mouse or keyboard input. The iMac DVD-ROM Update improves the DVD-ROM drive's ability to read some of these CDs and to determine more quickly whether a disc can be read.

4. Double-click the iMac DVD-ROM Update application to open it.

5. Click Continue.

IMPORTANT Do not reset, shut down, or turn off power to your computer while the iMac DVD-ROM Update is in progress. Doing so may damage your DVD-ROM drive.

Tips and Troubleshooting

If the iMac DVD Update isn't installed successfully, you see one of the following messages.

• "This update is not necessary."
• "The drive has already been updated."
• "This update is not intended for this DVD-ROM drive model or firmware revision."

  The DVD-ROM drive in your iMac does not need the iMac DVD Update.

• "This DVD-ROM drive cannot be updated."

  The DVD-ROM drive model in your iMac is of a type that cannot be updated. If your iMac DV computer has problems reading CD-ROM discs that can be read on other Macintosh computers, contact Apple or an Apple-authorized service provider for assistance. If your iMac DV computer can read most CDs, your DVD-ROM drive is operating correctly and you don't need this update.
