Apple start distributing the very first build of Mac OS X 10.6.5 to developers on Friday night. The new iteration is officially labeled as Build 10H525. Mac OS X 10.6.5 is, as suggested by the name, the fifth maintenance release of the Mac OS X Snow Leopard operating system. It follows Mac OS X 10.6.4, which was made available to consumers on June 15 of this year.
Apple has reportedly asked developers to focus their evaluation on iCal, Mail, Printing, 3D Graphics, QuickTime, and X11. Thus far, only two known issues have been documented. One is related to enabling UI elements in Web Views such as in the iTunes Store, while the other is caused when connecting to Exchange servers.
At the moment, the new features are currently unknown. However, Apple has pointed out that the developer build of Mac OS X 10.6.5 includes the latest graphics drivers, which are apparently being tested simultaneously in the Snow Leopard Graphics Update.
No word on when exactly Mac OS X 10.6.5 will be publicly released.
