Book excerpt: Every time Apple releases a new operating system, we pull together the most essential, in-depth, and up-to-date information about the Mac OS and create a new book that gives our readers access to it all in one place. With Snow Leopard now out and rapidly gaining acceptance, it's time for us to release Total Snow Leopard. Following in the footsteps of our popular, everything-in-one-place guides to Mac OS X (Total OS X, Total Panther, Total Tiger, andTotal Leopard),Total Snow Leopard is an information-packed 102-page book featuring just about everything you'll need to know about Snow Leopard-all features, great and small. We've taken the best of Macworld's coverage of Mac OS X and distilled it into this book, including contributions from such luminaries as Christopher Breen, Glenn Fleishman, Dan Frakes, Rob Griffiths, Joe Kissell, Ted Landau, Kirk McElhearn, Rich Mogull, Dan Moren, Jonathan Seff, Michael Scalisi, Derrick Story, Ben Waldie, and Sharon Zardetto. The book includes information to help you set up Snow Leopard smoothly and take advantage of its most important features. It'll also help you master the Web with Safari 4, get e-mail with Exchange, keep your Snow Leopard Mac secure, and increase productivity with text substitutions and the Services menu. We think this book is a great resource for everyone who uses Snow Leopard and hope you enjoy our Superguide. If you're looking for more help with OS X, iOS, and all things Apple, make sure to check out our other Superguides.
