Apple is seeding a new test build of Mac OS X 10.6.3 to developers, 10D552. The 737.2MB build 10D552 began circulating last night – the last beta reached developers last Friday, following January’s seeding of build 10D538. The code is said to continue many of the troubleshooting efforts taken with the last two builds, correcting problems with AirPort, OpenGL, graphics drivers and QuickTime X, while improving the performance of 64-bit Logic. Also fixed are some compatibility and reliability issues with third-party printers, and a glitch which causes background message colors to behave badly in Mail.
The release follows only days after the availability of build 10D548, which could imply that a public launch of the v10.6.3 update will happen very soon. The company may alternately have wanted to eliminate a critical problem, although no developers have complained about one in 10D548 so far. It is hoped that v10.6.3 might fix audio issues with Mac Pros.
