Written for readers who are inquisitive and confident enough to dig deep into their Mac, this book is for power users who want to customize and rev up Mac OS X to their liking. Completely revised and updated to cover new features and functionality of Mac OS X 10.4, the easy-to-follow format is organized into three primary parts: "Getting Started" introduces Mac OS X, how it's put together, and how it works. "Administration Essentials" gives readers the tools to examine how their system is running, and how to adjust all the knobs behind its operation. "Networking and Network Services" covers the ways Mac OS X interfaces with the world around it, including wireless and spontaneous networking. Developer Tools for Mac OS X, including Xcode, are discussed throughout the book where needed to accomplish tasks at hand. The appendices that follow include information for people who want to tweak things to run faster, better, or just differently.
