Mac OS - Mountain Lion - 004

Apple retail stores worldwide are reportedly planning “overnights” on Tuesday, July 24, which could indicate that OS X Mountain Lion is set to make its debut the following day.

If you’re unfamiliar with the term “overnights,” it is used to describe an internal Apple event which sees retail staff go into work at night to prepare the store for a product launch the following day. Staff will change banners and other signage, install new software on store devices if necessary, put new products on display, and more.

According to 9to5Mac, the overnights are expected to be “smaller” this year, because unlike previous OS X launches, Mountain Lion will not debut alongside new hardware. “One employee tells us that it is basically just a few guys running around with the master image installing it on every Mac,” the report said.

After Apple confirmed at WWDC that OS X Mountain Lion would go public this July, it certainly seems plausible that this is what these overnights are being held for. Furthermore, the company is set to hold its third quarter earnings call on July 24, and last year’s OS X Lion launch came the day after the same event.

Mountain Lion will be a $19.99 upgrade through the Mac App Store, and those who purchased a new Mac on or after June 11 will receive the upgrade for free.
