Apple Seeds Mac OS X 10.6.3 Build 10D538 to Developers
AppleInsider reports that Apple has seeded a new version of Mac OS X 10.6.3, termed Build 10D538, to select developers for testing. According to the report, the update addresses issues in several areas, including QuickTime X and Logic Studio.
More specifically, people familiar with Friday's beta say it includes an update to QuickTime X that, when finalized, will improve security and compatibility while simultaneously enhancing overall reliability. The release will also include tweaks that aim to enhance the performance of Apple's 64-bit Logic pro audio suite. Other planned improvements include better compatibility with third-party printers and OpenGL-grounded applications, those same people say.
One documented known issue reportedly remains in the latest build, involving the viewing of photos via Front Row.
Apple seeded its first test version of Mac OS X 10.6.3 to developers earlier this month, revealing a significant number of fixes in the new update, as well as several outstanding issues still needing attention at the time.
Mac OS X 10.6.3 also reportedly contains greatly improved support for OpenGL 3.0, which would offer significantly improved graphics performance should Apple implement full support for the standards. It is unknown at this time whether the latest 10.6.3 build has made any additional steps toward that goal.
