I received the book—the publisher overnighted me a copy. Next to two of the books I respect.

The book’s status is officially “published”—as stated on Addison-Wesley’s page for the book. Note also that it is listed as shipping. Amazon’s page usually takes some time to sync.

Since I keep receiving queries on accessing the light-related data associated with the ambient light sensor and the backlit keyboard on Apple notebook computers, here is a more detailed discussion, along with source code, on performing the following operations.  Retrieving readings from the ambient light sensor  Retrieving and setting the LED brightness value of the [...]

Besides the sudden motion sensor, Apple notebook computers contain other sensors (depending on the specific model). These other sensors can also be queried by user programs. This is a crude example that periodically retrieves readings from the ambient light sensors.

I received these in the mail today. Note that unlike the two volumes shown here, the final book is a single unit and is hardbound. The latter uses higher quality and thinner paper, so it is possible to fit everything into one unit.

Since someone asked: this source code is an example of programmatically receiving mouse events, with the option of filtering and modifying them, on Mac OS X 10.4 and up.

I have released a new version (2.5) of hfsdebug. The new version fixes a bug in the calculation of free space blocks on a volume, and now all features are supported on both the PowerPC and x86 versions of Mac OS X. In particular, hfsdebug no longer uses the /dev/kmem device for displaying kernel-memory-resident mount [...]

I am glad to share the following information about the book’s schedule. Publication date: June 16, 2006 Estimated in-stock date: June 23, 2006 In its final (published) form, the book has 1680 pages.

Mac OS X Internals: A Presentation is a Flash rendition of a presentation I recently gave.

EFI Programming on Mac OS X is a note on jumpstarting EFI development on Mac OS X. Prebuilt compiler toolchains for the PowerPC and x86 versions of Mac OS X are also available.
