Cocoa and Carbon, the application frameworks, are neatly described, but system programmers find the rest lacking.
Mac OS X and iOS Internals illuminates the darkest corners of those systems, starting with an architectural overview, then drilling all the way to the core.
- Provides you with a top down view of OS X and iOS
- Walks you through the phases of system startup—both Mac (EFi) and mobile (iBoot)
- Explains how processes, threads, virtual memory, and filesystems are maintained
- Covers the security architecture
- Reviews the internal Apis used by the system—BSD and Mach
- Dissects the kernel, XNU, into its sub components: Mach, the BSD Layer, and I/o kit, and explains each in detail
- Explains the inner workings of device drivers.
