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).

WHAT'S NEW
Version 1.6:
  • Snow Leopard compatibility [feature 2845796] (Thanks again to Steve Anthony)
  • Improved limits on output from syslog to STDOUT
  • Simplified startup of services on Leopard and Snow Leopard
  • Fixed bug in creation of user account lists in Snow Leopard where system accounts would show up
  • S.M.A.R.T. status verification is now being done in the expert mode. I still want to implement this using smartmontools, but for now diskutil will do.
  • Blessing of Mac OS X System folders on attached volumes is now possible. This is a primitive bless, ie, it does not create boot files, but simply blesses the chosen System folder and (optionally) sets it to be used for startup on next launch
REQUIREMENTS
Mac OS X 10.4 or later.

MACZENTRUM  Once you install it, it's not app to be run from Finder.

1. You have to reboot, and while you hear the chime you have to press Command-S to enter Single User Mode.

2. You'll enter a Unix interface (don't panic), you'll notice as it's black screen with lots of code and stuff...

3. once the #root prompts, you have to type: applejack auto restart: this means: runs the AppleJack app, does the cleaning automatic and once it finishes, the mac restarts.

In my particular case, it solved lots of problems my system was carrying. AppleJack does a great job.

Hope i've been didactic enough for you to understand.

DOUG EDDY  I am thrilled with the update. Have missed it and my OS needs a good swift kick in the pants cleaning! Applejack has kept me problem free for years. Many thanks to the developer for keeping this invaluable program going!

AESCHYLUS  This is an essential utility, and it has worked every time I've needed it. Outstanding, a must-have. Even if you are timid about seeing console text on your Mac screen, install this anyway NOW before you have trouble. If you have a problem later, it is easy enough to figure it out and fix the issues.

This program is simple, and it just works. So even if there is no real GUI, it is a true Mac program.

Kudos to the author for putting in all this work for our benefit.

DR_SG  Some time ago, a colleague of mine mentioned AppleJack. It sounded useful, so I downloaded and installed. Not two weeks after I installed AppleJack, I was unable to boot my Macbook Pro. I used AppleJack, and I was sorted out straight away. All of my usual 'tricks' had been unsuccessfully exhausted before I tried AppleJack. Cannot recommend it highly enough.
