In the hustle and the bustle of last week's full-court press press, there was a bit of Mac news worthy of mention: the indispensable AppleJack single-user utility has been updated for compatibility with Snow Leopard. If you never need AppleJack, you'll be happier, but if and when you do need it there's no doubt it can save your sanity (and your Mac).

Developed by Kristofer Widholm with an assist from Steve Anthony, the AppleJack utility can only be run when you boot your Mac into single-user mode (by holding down the S and Command keys during startup). It will allow you to clean caches, run repairs and generally happy-make your unhappy Mac. The tool is open-source and free, so go get it.
