DESCRIPTION
AppleJack is a user friendly troubleshooting assistant for Mac OS X. With AppleJack you can troubleshoot a computer even if you can't load the GUI, or don't have a startup CD handy. AppleJack runs in Single User Mode and is menu-based for ease of use.

Using AppleJack, you can repair your disk, repair permissions, validate the system's preference files, and get rid of possibly corrupted cache files. In most cases, these operations can help get your machine back on track. The important thing is that you don't need another startup disk with you. All you need to do is restart in Single User Mode (SUM), by holding down the command and s keys at startup, and then typing applejack, or applejack auto (which will run through all the tasks automatically), or applejack auto restart (which will also restart the computer automatically at the end of the process).

CTKMND  It does run for me under 10.5.6 except it seems like it is responsible for banging up some of my preferences when run on auto or check prefs. How does AJ validate the prefs? Is AJ or some Apple utility it calls that screws up?

If you installed it previous to the 10.5.6 upgrade have you tried a re-download and re-install?

It's a very good safeguard repair, especially for portables so it would sure be nice to see it updated!

Stay well!

SOUNDFREAK  This soft actually fixed my boot volume, where Onyx and Apple Disk Utility failed.

This is a great piece of soft !! A MUST-HAVE that should be included in any OS X machine.

Thanks !!

FREDCH  Since I upgraded to 10.5.6, Applejack does not work. When I restart and hold command+s, I get only an opportunity to run fsck. The former script does not run.

Any help appreciated.

KRYSIA  This is a small, fabulous, and indispensable piece of software. It repaired what Onyx could not. It repaired what Apple's Disk Utility could not. It repaired what Apple's Disk Utility could not from a different startup (original) disk could not.

My disk is in the Green again, and it was so incredibly easy to do. Followed their instructions.

After initial restart, Safari had odd behaviors: I'd click the X to close a tab & nothing would happen. I'd go to push the scrollbar up or down after just doing so, & it wouldn't work unless I clicked on its background first. However, their instructions in the read-me file stated there might be some weirdness, and that a restart of the computer should fix it. I restarted, and *knock wood* so far, zero problems. Ran Onyx; needed to repair disk. Ran Disk Utility from a startup disk, and this time, the one thing left that was wrong with it after Applejacking it was fixable. Disk Repaired. To be safe, I restarted one more time, ran Onyx, disk is fine. Hooray!

Very happy over here.

Definitely donated.
