Emergency Repairs

Are you seeing some strange behavior on your Mac? Is your Mac not getting past the boot phase? Is it difficult to get to Disk First Aid? Have you lost your OS X install disk (shame on you!)? Then you had better hope you have AppleJack installed.

AppleJack is the Swiss-Army Knife of emergency Mac repairs. When trouble's a-brewin' and you can't get to your favorite Disk Utility, just boot into Single User Mode (boot while holding command-s) and enter "applejack" (without the quotes). With AppleJack, you will be able to repair your disks, repair permissions, cleanup cache files, validate preference files, and remove swap files, technically without having to boot your computer. Remember, you need to have AppleJack installed BEFORE you have any serious problems with your Mac. Also, if you follow MacMerc's guide to routine maintenance, you should never need to use AppleJack. Though, it's still nice to have around, just in case.
