Mac OS X 10.6.3 Build 10D573 Reaches Developers [Seed Notes]

Apple seems downright stubborn to hold off the public release of Mac OS X 10.6.3, with a third test build handed to developers in less than ten days, World of Apple has confirmed. The build, labeled 10D573, contains the same known issue as the previous two, and asks developers to focus on new areas of the software.

Having been able to get confirmation of the new seeding, World of Apple also went on to post the actual seed notes included with the latest 10.6.3 build. It makes a note of its own, outlining that, “The build number differs once again by only one numeric digit.” As a combo update, the software weighs in at 790MB. In delta form, it is 725MB in size, the source reveals. “10D573 contains one known issue and continues to advise developers to focus on new areas of the operating system,” World of Apple adds, and proceeds with posting the documentation in question.
