After installing MacOS X, I had enough questions and problems that I thought a good introductory book would help. I immediately ordered this book. By the time it arrived, it was already too basic - I'd figured out the things the book claims to cover.Between simple experimentation and using Help, you will quickly learn more than you will ever get from reading this book.In addition, the book is padded with information about thestatus of various 3rd-party programs running on Mac OS X. This information was obsolete before the book left the printers! To find out about the status of 3rd-party apps, visit Apple's website or the various company websites.
