Can I repair my G5 without the Mac OS X installation disk? It has been having problems (will not turn off, will not wake from sleep, and others) so I ran disc utilities with the following results. The problem is that I do not have the installation disk. Can you help, please? Thank you!

    Start up the computer with the Shift key held down; this runs a disk repair tool on the startup disk. There is no onscreen acknowledgement other than the 'safe mode' message.

    Hi flashnut;

    The system will not allow work on the drive it is running on. Hence the reason to boot from the install media. If you have another drive from which you can boot that might do.

    Holding the SHIFT key down while starting the computer worked! I checked the disk using disk utility and now it appears to have no issues. Thank you!

    Booting into Single User Mode on startup gives you the ability to run diskutil in the form of fsck command.

    Your DVD should not be used to repair permissions and is likely older so I always use fsck (there is also Applejack and Leopard Cache Cleaner both can run diskutil).

    Better yet is to have a small emergency partition to run disk repairs.
