Was wondering if someone could provide some good book recommendations for the OS X operating system. I have just fairly recently purchased and iMac and a MacBook along with a book by Pogue called the "missing manual" or something similar. It's an excellent book but I feel that I now have a pretty good grasp of the basic OS X operating system features. I've also been employed in the IT industry working with the UNIX operating system for several years and I'm looking for a more advanced OS X book resource. Any suggestions? Don't feel you need to limit your suggestions to books either. Any pointers towards outstanding periodicals would be welcome as well.
