Just 16 days after the release of Mac OS X 10.8 Mountain Lion, Apple has seeded the first maintenance update to developers. The update, dubbed version 10.8.1, is expected to fix some known issues with Mountain Lion. Apple has asked the developers through the release notes to focus on testing the Active Directory, Microsoft Exchange in Mail.app, PAC Proxies in Safari, SMB, USB, and Wi-Fi and audio when connected to a Thunderbolt display. The update was seeded with no known issues.
Probably one of the most prevalent bugs in OS X 10.8 is the Wi-Fi and audio problems when connected to a Thunderbolt display. Users have reported stuttering audio followed by the entire system freezing up. Users have also reported issues with sustaining a connection to a Wi-Fi network. In the 10.8.1 update, Apple has asked developers to test these two factors. Therefore, it seems likely that these bugs will be patched after updating.
An issue that was not addressed in 10.8.1’s release notes is faster battery drain. Users have reported a significantly lower battery life since upgrading. There are several theories to why the battery is draining faster, including increased CPU usage due to the system upgrade, network fetching, or search indexing. If these theories are true, the battery life should return to (or close to) normal after the system has had time to adjust to the upgrade. It is possible that there could be an underlying problem causing decreased battery life. This type of problem may or may not be fixed in 10.8.1…only testing over time will tell.
There does not appear to be any added features, including Facebook integration and iMessage phone number merging. These features may be added in a later seed of 10.8.1 or in a new version altogether. There is also no set release date for 10.8.1. Registered Mac developers can install the update today from the developer center.
