Mac OS X 10.6 Snow Leopard: the Ars Technica review. The essential review: 23 pages of information-dense but readable goodness. Pretty much everything I know about Mac OS X internals I learnt from reading John Siracusa’s reviews—this one is particularly juice when it gets to Grand Central Dispatch and blocks (aka closures) in C and Objective-C.

How Time Machine works. From John Siracusa’s Leopard review. The bad news is that Time Machine doesn’t deal well with huge files that have small changes made to them... such as Parallels VM images.

Mac OS X 10.5 Leopard: the Ars Technica review. John Siracusa’s 17 page review of Leopard, covering everything from UI tweaks to DTrace sample code. Smart use of embedded video and audio too—I suggest setting aside at least an hour to work through it all.
