Yes, it's old. You see Tiger and you think 'not for me'. This is the most thorough, and informative OSx Unix guide I've come across. I'm running El Capitan now, and have found most of the information still completely relevant and useful. The book is a beast- but if you're going to learn, get this one and hunker down. The Pocket Guides and other 'overviews' won't give you the kind of thorough background and understanding to actually apply what you are learning, rather than just repeat verbatim lines of code into a terminal window. Plus, you can come across these pretty inexpensively now- it'd be a $80+ book if it were released today.

Bonus points: Buy it used for under $10 and make highest ROI Apple related purchase ever. That's less than a lightning cable! Thus book is a must-have for those who want to dig a little deeper into the UNIX behind OS X. The sad thing is that it doesn't have some of the newer features in OS X documented. Still, it's worth it for an introduction to what's behind all those pretty icons and I would recommend it both to UNIX beginners and seasoned UNIX users who may be new to OS X. One thing to note - I haven't traveled to the authors website to see how much 'updating' may have been done - I'm going to visit there soon and will modify this review if I find updated information to features new since Tiger. This is an ideal reference for programmers, system administrators or 'power users' with motivation to gain proficiency with the Mac OS X Command Line.
