Hacking Mac OS X Tiger: Serious Hacks, Mods and Customizations: Extreme Tech

I love clever tips, and Scott Knaster delivers a ton of them here, many seen nowhere else. But this tome goes way beyond tips, diving into the gnarly details of Tiger that others have glossed over, such as application internals, Widget construction, and Unix command language. So many Mac books are just a rehash of the surface of the user interface. Scott's book is way ahead of the pack.

I was looking for a book with medium to advanced info on Tiger and this one seemed to fit the bill. I was a little concerned at first when it started off with user tips which were handy, but I wanted more technical stuff. The latter parts of the book really delivered. There's well done sections on Automator and Quartz Composer. The best part is the last chapters which have programs with source for Dashboard, Spotlight, dock badging, and a few more. My advice is skim the first few chapters and pay attention to the rest.
