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).

"I don't get it"

So after reading that this program allows you to run a permissions repair on a disk that won't boot up, I downloaded it to run on a Macbook that won't boot up at all (gets stuck at the spinning dial, but it will boot into single user mode) and I can't find the installation disk to run a permissions repair.

The instructions simply say to double click the pkg to install it. That's very nice if I wanted to install it on the Mac I'm using to download the software but the whole point was to get it to run on a Mac on which I can't load the GUI at all.

There are no instructions that explain how to actually get the utility onto the machine that is having problems.
