Today’s build release, build 10D522, is the first release for Mac OS X 10.6.3 and the build focuses on various OS fixes and enhancements related to application updating, Displays preferences, iTunes hangs, and ColorSync Utility Filters.

The final release of Mac OS X 10.6.3 is expected in late January/February 2010.
