Lots of articles geared towards Mac OS X, Terminal, Mac Security (for Mac OS X), along with other articles.
Mike Bombich's OS X Tips Page (4,300)
Mike has a page of important how-to's, including moving OS X from one partition to another, removing unneeded languages, and how to move your swapfile to another partition.
A French-language OS X Server site. It looks to be full of good information, and babelfish (on altavista.com) might help translate some of the pages if you don't speak French!
Mr. X Super Sexy Mac Links (2,349)
A carfully selected, hand picked, list of OS X must-have applications and info links. Save hours of research and testing, go straight to the best apps and most useful info available. Included is a concise description of each link and any other information that might make your Mac experience more enjoyable ;)
OS X App Direct Downloads (1,508)
A page designed to simply list the name of an OS X application followed by a direct download link (no redirects, no CGI, etc.). A short list of apps at present, but an interesting idea.
OS X Basics (1,364)
A nice overview of OS X from a beginner's perspective, covering things like definitions, privileges, and user interface.
OS X Center (2,393)
A very thorough and well laid out site (complete with Aqua look), available in both French and English. Main contents at this point are pointers to other OS X resources around the web.
