Michael McCracken writes "Finally, a new OS X programming book that isn't just another introduction to Cocoa. This book adds a lot to the available references by covering the system as a flavor of Unix, presenting information on important topics like sockets, multithreading and pipes, which other OS X books leave out. It also includes coverage and sample code for some of the unfamiliar new technologies that have been introduced recently, such as the Keychain, Rendezvous (aka Zeroconf), and using the Security framework to authorize users."
