This past Wednesday, on 16 May 2012, Apple gave developers another updated version of OS X 10.8 Mountain Lion Developer Preview 3. This, is the pre-release build of the next major Mac operating system refresh.
The update, or Build 12A206j, is now available for download by registered Mac developers. At the moment, details about the release are few. Yet, it looks like Apple is telling developers that the MacBook Pro released almost 5 years ago (the mid ’07 models) would not be compatible with the new build, although a future update will remedy this glitch.
For now, it appears that only minor performance issues (related to Fast User Switching, the Share menu, etc.) still require moderate tweaking by Apple. Apart from these, there are no major headaches on the horizon.
At the time of this news report being written, the rumors suggest that Apple is just days away from raising the curtain on its new MacBook Pros at the WWDC in early June. If this is true, then Mac users can expect the refreshed Macs to come with Mountain Lion pre-installed this summer.
