I found OS X in a nutshell a pretty good reference. If you were an early adopter of OS X, you've either figuered out most of the information in the first half of the book using survival instincts, or you don't care about the less-than-obvious OS X panels, apps and utilities.

I have to compliment the writing team for covering a gazillion different mac and unix topics in one volume. That being said, some of the topics are a little thin to apply to practical use without some additional information.

I really liked the DAMP chapter. I never had the opportunity to lauch a web server before, but I had Apache up and running in 5 minutes, exactly as documented!

A pretty good all-in-one refernece for those of us who don't touch unix every day, or never earned a sysadmin merit badge. By the time this book wears out, we'll all be using OS XV.
