10.6.7 fixes Back to My Mac, Mac App Store
[Updated: added information about special version for 2011 MacBook Pros with Thunderbolt] Apple has flooded its support website with a host of software updates, most prominently Mac OS X 10.6.7. The patch is available in client and server versions; the former is described as making "general operating system fixes" targeting stability, security and compatibility. In particular though it should improve the reliability of Back to My Mac, and quash several bugs in the Mac App Store, as well as an issue affecting file transfers to SMB servers.
A separate download is available (either directly or through Software Update specifically for the new, 2011-model MacBook Pros (the first machines to feature Thunderbolt). The separate file is said by the company to improve graphics stability, external display compatibility and "minor FaceTime performance issues." Apple received some reports from 2011 MBP owners complaining of external display flicking, blanking and other issues.
The separate update results in 2011 MBP owners having a slightly different build than other Apple notebook owners -- 10J869 rather than 10J3250.
The server update deals with a host of additional issues, including several related to Wikis. Reliability tweaks affect web server restarts and using Epiphan gear to record videos in Podcast Producer. iChat Server should finally function properly when dealing with .local domains, and 12-digit hardware serial numbers will now display accurately when using Server Admin.
Apple has also issued matching client and server security updates for Snow Leopard, labeled 2011-001. These close dozens vulnerabilities also fixed by Mac OS X 10.6.7, in areas such as Apache, Ruby, PHP, ATS, QuickTime and ImageIO.
