Mac OS X 10.6.3 imminent?

After only two days

since the last build was seeded, Apple has pushed another 10.6.3 version out to developers. The newest build is numbered 10D572 and focuses on Graphics Drivers, Quicktime, Images & Photos, Mail, and Security Certificates. In addition, the build also includes:

• Compatibility issues with OpenGL-based applications

• Performance improvements for 64-bit Logic

• Changes to QuickTime X that increase reliability and improve compatibility and security

• Printing reliability and compatibility with third party printers

• Issues resolved that prevented files from copying to Windows shares

• Issues resolved with recurring events in iCal when connected to an Exchange server

• Issues resolved that prevented files with the "#" or "&" symbols in their names from opening in Rosetta

• Issues addressed that caused background message colors to display incorrectly in Mail when scrolling

• Issue resolved that caused machines using BTMM and the Bonjour Sleep Proxy to wake unexpectedly

Like the previous build, there is a single known issue: Safari 4.0.5 will be re-offered by Software Update after upgrading to 10D572 from a previous seed.

As a general rule, the closer build release dates come to one another, the sooner the build will be released to the general public. 10.6.3 seems like it could very well be the biggest update to Snow Leopard since its launch last August. If the improvements are significant, it's very likely that Apple will soon press 10.6.3 discs to be sold in retail stores, much like they did with Mac OS X 10.5.3.
