OS X Internals: A Systems Approach (2nd Edition)

Now fully updated for the latest Mac OS versions and hardware, OS X Internals: A Systems Approach, Second Edition illuminates Mac OS internals from a linear perspective, guiding you through what's happening at the fundamental level at each step from turning on power to presenting a running operating system.

Covering modern Mac OS internals in unparalleled depth, three leading experts discuss Mac firmware, the bootloader, user-level startup, xnu, low-level services, processes, memory, interprocess communication, kernel extensions, file systems, HFS+, and more.

Indispensable for developers of device drivers and many specialized applications, OS X Internals: A Systems Approach, Second Edition will be equally valuable to anyone who wants a profound understanding of how modern Macs work "under the hood."
