Apple Releases Mountain Lion 10.8.2 w/ Facebook Integrationby Saumitra Bhagwat on September 19, 2012 2:22 PM EST
As expected, Apple has released Mountain Lion 10.8.2 today in conjunction with the release of iOS 6. A slightly updated build (12C53) was released to developers last week as a follow up to build 12C50 that originally introduced Facebook integration.
Users had complained about significantly reduced battery life after upgrading to Mountain Lion, an issue that had not been addressed in 10.8.1. Battery life on the new Retina display MacBook Pros seemed to have taken a particularly bad hit on Mountain Lion. However, independent tests conducted by MacObserver have found that 10.8.2 significantly improves battery life on both HDD and SSD based MacBooks and brings it back up to the levels seen on OS X Lion 10.7.4.
In addition, 10.8.2 also brings a host of other improvements and bug fixes such as support for more languages for the built-in dictation feature, PowerNap support for the Late 2010 MacBook Air, shared Reminder lists and tigher phone number integration for iMessages and FaceTime calls, amongst others.
In any case, the update is now available via Software Update, so head on over and update away.
