Apple Releases Update To OS X Mountain Lion Developer Preview As Release Draws Near

There's a new Mountain Lion on the prowl.

Apple today issued an update to its third OS X Mountain Lion developer preview. The update (Build 12A206j) can be downloaded now by registered Mac developers.

The second update to the latest Mountain Lion developer preview doesn’t seem to contain anything substantial, but Apple is obviously gearing up for the public release of its next-gen desktop OS this summer.

Apple released the third Mountain Lion developer preview on May 1st, and you must be running that preview to install the second update in Software Update. The update notes that “MacBook Pro 3,1’ models are not compatible with this build, meaning Macs released in the second half of 2007. Apple will fix this issue before Mountain Lion goes public.

Rumors are saying that Apple will unveil new MacBook Pros at its WWDC conference next month, and the company is expected to also address Mountain Lion and hopefully give a more specific release date than “late summer.” Based on the past, the summer’s new Macs should ship with Mountain Lion pre-installed.
