AppleJack Is The Basic Mac Safety Utility You Need.
Troubleshooting a wonky Mac can be a challenge. I’m the administrator for over 100 Macs which run OS X Leopard and Tiger.
One of my most beloved utilities to help troubleshoot an errant Mac is AppleJack, now Leopard compatible. About time.
AppleJack is something of a geek’s utility, a troubleshooting utility for Macs that have gone astray, an assistant that is there only for the bad times.
There are many utilities which do some of what AppleJack does. They repair permissions, check and validate your Mac’s system’s.... (excerpted).

I think you have to type
applejack auto restart
to run through the scripts and restart. Or you can type “shutdown” at the end to shutdown.
I LOVE this utility. In the case you can’t even boot up, this can save your bacon.
This new AppleJack has another trick. You can type ‘x’ at the prompt and enter an advanced mode. I’ve only played with it a little, performing the memory test.
Warning: The memory test makes the ‘repair permissions’ seem like a nanosecond.

AppleJack is da bomb. You may never need it, but when you do it’s a Godsend, a gift from heaven. Probably 8 out of 10 Mac problems come from a dying hard drive, or corrupt something or other—hard drive, permissions, preferences. AppleJack lets you get into your Mac without using the start up DVD so you can run basic repairs. Love it.

“If you happen to have your Mac’s startup DVD (sure, you carry that around with you all the time, right?), then you can use that to start up your Mac and check your files, permissions, even repair your Mac’s hard disk.”
That’s why I create a small partition on my laptop—very useful to boot from when traveling in case of problems with the main partition. Applejack is still useful, of course.

Is it just me, or does the name of this app remind anyone of the movie “The Computer Wore Tennis Shoes”?
I have downloaded it, and so far have not had to take advantage of it yet. Hopefully I will never have to use it, but it’s good to know it’s there if I need it.
