Apple seeds another build of 10.6.3 to devs

Apple seeded another build of OS X 10.6.3 today. This latest build number is 10D558. This is just nine days after Apple seeded build 10D552. iPhoneinCanada is reporting that the current build focuses on Apple Filing Protocol, AirPort, Graphics Drivers, and QuickTime, as well as the following:

• Performance improvements for 64-bit Logic

• Addresses compatibility issues with OpenGL-based applications

• Includes changes to QuickTime X that increase reliability and enhance security

• Improves printing reliability and compatibility with 3rd party printers

• Addresses issues that cause background message colors to display incorrectly in Mail

• Issues that caused machines using BTMM and Bonjour Sleep Proxy to wake unexpectedly

• Issues with recurring events in iCal when connected to Exchange servers

This is the fifth build of 10.6.3 Apple has released since January. While no time frame for release is ever given, generally the closer in time the builds come to one another, the better likelihood that a release is imminent.
