OS X Mountain Lion has been around for two weeks now and users slowly start to report bugs they have found in this system. Mountain Lion feels much better than OS X Lion since it has over 200 new features and improvements and it was well received by Mac users and got downloaded over 3 million times in the first 24 hours after it become available on App Store.
At first App Store littered with positive reviews from users but now you can see that many users are starting to complain about sluggish performance and massive battery drain for MacBook Air and Pro models. I haven’t noticed any of these issues on my MacBook Pro but my girlfriends MacBook Air (Mid 2011) become very slow and battery lasted for only 3 hours instead of 6-7 like it was before. I did a clean install for her MacBook Air and now it everything works fine. I have no idea what causes this problem but at least you can solve it until Apple releases OS X Mountain Lion 10.8.1 which soon will be seeded to Mac developers and AppleSeed users.
We are not sure about the scale of this problem but I have seen dozens of threads on Apple official forum and many other Apple products related discussion boards. This isn’t the first time when iOS or Mac are facing such situation and I guess Apple does not learn from its experience and continue to make the same mistakes over and over again. I guess this has something to do with iCloud or Social Network integration since it takes more resources pull information from these services.
Thankfully Apple is working on updated that would take its operating system to version 10.8.1, hopefully addressing battery and performance issues that have been reported to Apple. Many members of the AppleSeed program – a program that allows regular users to access pre-release software and test it in the daily tasks and report errors back to Apple – have begun receiving notifications about OS Mountain Lion 10.8.1 beta availability. In the next step, Apple will release pre-release version to registered mac developers for further testing before it reaches everyone else.
Apple remains silent about the changes we can expect in the first Mountain Lion update, but I guess that battery life and performance issues are certainly a priority for Apple and its developers. We will bring you more information once OS X 10.8.1 update will reach official Mac developer channel so we can start testing this version, meanwhile keep your fingers crossed that Apple will find the way to fix battery and performance problems.
