AppleCare Protection Plan CD cannot start up all Macintosh computers

TechTool Deluxe can still perform some tests if you copy it from the AppleCare Protection Plan CD to your computer's hard disk.

In order for TechTool Deluxe to perform any write-based tests or perform repairs, the computer must be started up from the AppleCare Protection Plan CD or from a Mac OS 9 Install CD (for computer models that will start up in Mac OS 9).

This document addresses three possible situations:

• If your computer will start up in Mac OS 9 and you have a Mac OS 9 CD that can start up the computer
• If your computer will start up in Mac OS 9 but does not have a Mac OS 9 CD that can start up the computer
• If your computer will not start up in Mac OS 9

Your computer can start up in Mac OS 9 and you have a Mac OS 9 CD that can start up the computer

The following steps will only work with the Mac OS 9 version of the TechTool Deluxe application versions 2.5.2 through 2.5.7. The Mac OS X versions of TechTool Deluxe, versions 3.0 and later, cannot be used in this manner.

The Mac OS 9 and Mac OS X versions of TechTool Deluxe have similar tests. If your computer can start up from Mac OS 9 and you have a CD that can be used as a Mac OS 9 startup disk, you only need to use the Mac OS 9 version of TechTool Deluxe to test your computer.

1. Make sure you have the latest update of TechTool Deluxe.
   
2. Start up the computer up from the hard disk.
   
3. Insert the AppleCare Protection Plan CD.
   
4. If you had to update your copy of TechTool Deluxe, the TechTool folder is already on your hard disk. If you did not have to update, copy the TechTool Deluxe folder (for your language only) from the TechTool Deluxe (Mac OS 9) partition of the AppleCare Protection Plan CD to your computer's hard disk.
   
   There are three versions of the TechTool Deluxe folder on the AppleCare Protection Plan CD. Copy the folder that is for your language version--you do not need to copy all three folders.
   • "TechTool Deluxe" is the English version
   • "TechTool Deluxe F" is the French version
   • "TechTool Deluxe J" is the Japanese version
5. Eject the AppleCare Protection Plan CD
   
6. Insert the Mac OS 9 System CD that came with your computer.
   
7. Restart your computer.
   
8. Press C to start up from the CD.
   
9. Use TechTool Deluxe in the folder that you copied to your hard disk.

If your computer will start up in Mac OS 9 but does not have a Mac OS 9 CD that will start up the computer

If your computer did not come with a CD that will start the computer up in Mac OS 9 and the AppleCare Protection Plan CD that came with your AppleCare Protection Plan does not start your computer, contact Apple to obtain the latest version of the AppleCare Protection Plan CD.

If your computer does not start up in Mac OS 9

If your computer does not start up in Mac OS 9 and the AppleCare Protection Plan CD that came with your AppleCare Protection Plan does not start your computer, contact Apple to obtain the latest version of the AppleCare Protection Plan CD.
