Vacation Blackout Hints at Late July Release for OS X Mountain Lion
MacRumors has now heard from several employees at a third-party firm offering technical support for Apple products that their company has imposed a vacation blackout from July 22 through 29, requiring "all hands on deck" in its desktop and portables division to support an unspecified event.
Speculation naturally turns to OS X Mountain Lion as the event in question, although some potential customers may be hoping that new iMac and/or Mac mini hardware could arrive at the same time. Apple scheduled just such a simultaneous hardware/software launch last July, introducing new MacBook Air and Mac mini models alongside OS X Lion.
