For the seventy-something-th time (Ive lost count), this book is dedicated to the love of my life, my wife and best friend, Lisa, the person who taught me almost everything I know about almost everything I know (except technology).

And, again for the umpteenth time, this book is also dedicated to my adults (theyre not kids anymore), Allison and Jacob, who love Apple gadgets almost as much as I love them (my adults, of course, not my gadgets).

Finally, although it makes me sad, I dedicate this book to my longtime technical editor, the late Dennis R. Cohen, who did a fabulous job on every edition of OS X For Dummies prior to this one. This ones for you, Dennis.

Also for the seventy-something-th time, hats off to my super-agent, Carole Swifty Jelen, who has represented me for as long as Ive been writing books almost 25 years and you are still the worlds greatest agent.

Special thanks to everyone at Apple who helped me turn this book around in record time: Keri Walker, Monica Sarkar, Janette Barrios, Greg (Joz) Joswiak, Teresa Brewer, and others too numerous to mention. I couldnt have done it without you.

Big-time thanks to the gang at Wiley: Kyle Worry-Free Looper, Aaron Back in Black, Andy Big Boss Man Cummings, Barry Still No Humorous Nickname Pruett, and everyone else at Wiley who put their heart and soul into getting this book to you.

Thanks also to my family and friends for putting up with me during my all-too-lengthy absences during this books gestation.
