Mac OS X and iOS Internals: To the Apple's Core, Volume 1 User Mode

Greatly expanded and updated from Jonathan Levin's original Mac OS X and iOS Internals: To the Apple's Core, this new edition is now two volumes with Volume 1 an expanded treatment of User Mode and Volume 2 The Kernel.

In Volume 1, User Mode, Levin details Mac OS X and iOS for power users beyond where the documentation leaves off.

It covers:

• The Architecture of OS X and iOS including The User Experience Layer, Filesystems, Frameworks, and libraries
• OS X and iOS Technologies and in particular, the parts that are built on BSD
• Executables and binaries
• Process and Thread Internals including updates to 64-bit
• IPC in OS X and iOS with explanations of Unix, Mach, and XPC
• Details on the Objective-C and new Swift runtime environments
• Process Tracing and Debugging with DTrace and KDebug
• Boot, Panic, and Shutdown
• Launchd and the GUI Shells
• All new coverage of iCloud and networking protocols
• All new coverage of OS X and iOS Security

Along with Volume 2 The Kernel, this is the definitive documentation of the inner workings of Apple operating systems for system-level developers, kernel hackers, and power users.
