Mac OS X was released in March 2001, but many components, such as Mach
and BSD, are considerably older. Understanding the design,
implementation, and workings of Mac OS X requires examination of several
technologies that differ in their age, origins, philosophies, and roles.

Mac OS X Internals: A Systems Approach is the first book that dissects
the internals of the system, presenting a detailed picture that grows
incrementally as you read. For example, you will learn the roles of the
firmware, the bootloader, the Mach and BSD kernel components (including
the process, virtual memory, IPC, and file system layers), the
object-oriented I/O Kit driver framework, user libraries, and other core
pieces of software. You will learn how these pieces connect and work
internally, where they originated, and how they evolved. The book also
covers several key areas of the Intel-based Macintosh computers.

A solid understanding of system internals is immensely useful in design,
development, and debugging for programmers of various skill levels.
System programmers can use the book as a reference and to construct a
better picture of how the core system works. Application programmers can
gain a deeper understanding of how their applications interact with the
system. System administrators and power users can use the book to harness
the power of the rich environment offered by Mac OS X. Finally, members
of the Windows, Linux, BSD, and other Unix communities will find the book
valuable in comparing and contrasting Mac OS X with their respective
systems.

Mac OS X Internals focuses on the technical aspects of OS X and is so
full of extremely useful information and programming examples that it
will definitely become a mandatory tool for every Mac OS X programmer.
