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

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

So it was a last chance trial and it worked!!!
So yes, this is essential: install it and forget it until the day you might need it!
I haven't tested it since I updated to Leopard, but I wonder if it would be faster to fix permissions (as you might know it's awfully slow on PPC Leopard).
Anyone tried?

Oh, and by the way, I'm not absolutely sure, now that I think about it, that it was AppleJack that saved my partitions, it could be another of the same breed of great utilities: Testdisk (http://www.macupdate.com/app/mac/27683/testdisk) as I've used both of them when I was looking for salvation! ;-)

Of course it's fast but it's hard to say if it repaired them correctly... (I haven't found nothing clear about it on the web)
I just can say that it doesn't look to harm anything.

The benefits of Lion are so questionable vs SL that — except if you own the ultimate Mac model which only runs Lion — the answer is clear...

I would frankly be suspicious of the developer if he had updated AppleJack for Lion compatibility in early 2010. I like to think I'm rather open-minded, but I am unaware of any major advances having been made in the field of time travel. Furthermore, if the developer had access to some method of time travel, I might think him a bit unimaginative for only bothering to use it to release free software well before it is needed.
Putting issues of calendars and quantum physics aside, I do understand your frustration at the delayed update of this software. I have already received a full refund of my purchase price, and I suggest you demand one as well. Perhaps once the developer has had to issue numerous refunds (of $0.00 each) for this software, he will begin to see the gravity of the situation.

I also used the included "memtest" application to test newly installed RAM, and that also worked the same as before.
So, people should feel free to go ahead and use AppleJack the same way as they did under Snow Leopard. The only thing that's broken is permissions repair. Everything else works OK, including memtest and auto/AUTO mode.
One last tip, when booted into OS X normally, if you want a quicker way to repair permissions without having to start disk utility, you can do it at the command line in Terminal like this:
diskutil repairPermissions devicename
Use the "df" command to find the device name for your drive, so that the final command looks like this:
diskutil repairPermissions /dev/disk0s2
I made a simple shell script called "repairperms" containing that command, and I now use that instead of firing up disk utility when I want to repair permissions.
Once again, this only works when booted into OS X normally, not in single-user mode.

The most important thing is that it is safe to use with Lion in manual mode, without any updates.
While the ability to use disk utility in recovery mode somewhat eliminates the need for disk repair and permissions repair at the command line, AppleJack simply can't be replaced for the thoroughness of it's ability to remove caches, not only for the general system, but individual user accounts. There is no substitute for being able to wipe those out when the full system isn't running. It actually does a better job than GUI cache cleaning tools that you run normally.

Unfortunately it does NOT work on my MacBook (1.83 GHz Intel Core Duo, 10.5.4) :-(
It just won't start. "Command S" doesn't bring up Apple Jack like it used to in the past. Hope it gets fixed soon.

Holding down command-s at boot time should work regardless of whether Applejack is installed or not. It's how you get into single user mode.
If command-s isn't working then you need to try another keyboard or reset the PRAM. Or contact your administrator.
Applejack works on my machines just fine.

In response to an email I sent to the developer today, the developer states that he has plans to update AppleJack but no time to do so:
"Plans, yes. Time? No, unfortunately. I don't know when I'll be able to get to it. My apologies."
