If you are a Mac OSX MacBook, MacBook Pro or MacBook AIR newbie or have used these laptops for some time without really "digging into" the system then this is a good book for you. The author does a good job of very clearly outlining the essential operating elements of your Mac laptop in an easy to understand style that may bore the more advanced users but is spot on for us beginning and intermediate users who will find the book to be a useful reference. He does a very nice job of walking us through the screens necessary to connect to wireless networks and even has a section on how to use your iPhone to tether WiFi to your laptop. He does a good job of taking us through the basic programs included with OSX including Mail, Safari, Address Book, iCal and the rest of the lot including the ins and out of iTunes and MobileMe. The book goes into linking the Mac laptop with external devices as well as providing some solid advice on how to keep your data "safer" through activating the firewall and how to use Time Machine. The troubleshooting section is OK but he doesn't go into much detail on how to utilize some of the software tools available for diagnosis but does provide a listing of helpful tools and where to obtain them. In summary, this book is really "The Missing Manual" (as many Que Publishing books were called previously) and should be an essential purchase with any new Mac laptop in order to obtain the most out of your system.
