Deals with Exchange, Thunderbolt, iMessage glitches
Apple has posted the finished version of OS X 10.8.1, its first update to Mountain Lion. The code is purely a maintenance release, solving a variety of bugs. Some notable examples include the Migration Assistant suddenly quitting, issues with Microsoft Exchange servers and Mail, and audio not playing properly via a Thunderbolt Display. One prevented iMessages from being sent.
Other fixes target systems freezing when using Pinyin input, problems with SMB servers using long names, 802.1x authentication with Active Directory credentials, and a glitch that stopped Safari from opening when using a Proxy Automatic Configuration file. The download is listed as just 24.2MB on Apple's support website, but filesizes can vary depending on the Mac being updated. The code should be available through Mountain Lion's Software Update feature.
Apple is already at work on OS X 10.8.2. What that might include hasn't been disclosed, but it could be intended to pave the way for iOS 6, which should launch next month if rumors about the next iPhone prove true.
