I’ve long felt much shakier about the OS X internals than I have about Linux or Solaris. It’s not been that clear to me where to turn to get solid OS X technical overviews without getting too distracted by fluff (OS X user sites) or by more detail than I necessarily needed at once (Apple’s OS documentation.)
Enter Ars Technica’s John Siracusa. The breadth he uses to review OS X Leopard (10.5) is amazing — he covers everything from kernel details to user-interface design decisions. The review is here, but he’s got plenty of other excellent articles covering great OS X topics like the Finder, HFS+, and the evolution of OS X file metadata.
Siracusa is one of the best technical writers I’ve read in a long time.
