This book goes down to the real nitty-gritty of multi-threading, interprocess communication, networking, performance tuning, distributed objects, kqueues, Bonjour, authentication, the keychain, and directory services. The tools are also covered: gcc, gdb, subversion, Shark, and Saturn. "This is the book to have if you need to understand the plumbing that makes Mac OS X work. It clearly explains the tools and APIs that can radically improve the performance and reliability of your applications." - Eric Peyton "I believe that this book is a must-have for any serious developer for the Mac OS X platform. In fact, it is the only book that I know that goes deep and digs up hard issues, real questions seeking real answers." - From the review on OSNews.com "I suspect this book will become a canonical reference, and may even be in need of a clever nickname." - From the review on Slashdot
