    I have a white 24" iMac.

    After 10.6.4, it said "update failed". Restart, gray screen with spinning thing. Won't get past that point. I tried everything (Safe boot, pram, repair disk permissions from CD, etc.). Any ideas?

    Did you have a backup?

    If yes, wipe the disk and restore your system from time machine, and then update.

    If not, find another mac, boot the iMac in target mode (hold T), connect it to the working mac using a Firewire cable and copy everything you need (user data). Then, wipe the disk, reinstall 10.6, update to 10.6.4 and copy back your data.

    Why wipe the drive when an archive and install will probably work?

    Did it pass the drive repair? either Disk First Aid or fsck?

    Repair disk found nothing...repair disk permissions found some stuff that it fixed.

    I called Apple. They told me to do an archive and install...doing that now. So to anyone with a white iMac...do not install 10.6.4...hah

    Thanks for your advice.

    This really bothers me since it's 100% Apple's fault this time. Aghhhhhhh

    When my drive was dying, I went back a couple times to an older version of the OS.

    So you can kill off 10.6.4 and replace it with 10.6.0 -- just need to sit through the upgrades again.

    Is is booting into single user mode?

    If so you might want to try ... /sbin/fsck_hfs -rd /dev/disk0s2 <-- where disk0s2 is the drive that shows up as you drive in the text above "singleuser boot -- fsck not done"

    line above Firewire (OHCI) will say something like "BSD Root: disk0s2, major 14, minor 2" -- just use the device you see here

    When I open up terminal it says "Terminal - bash - 80x24"

    How exactly do I do this? Thanks

    Mac OS X: How to start up in single-user or verbose mode

    Also tells you how, click on desktop, go to menu bar, click on HELP, type in "single user" click on "Starting up in single-user mode"
