In a KB article on its Support site, Apple has (possibly) spilled the beans on an upcoming Mountain Lion release geared towards addressing issues with the latest iMac line.
Apple this week posted a bunch of Support documents acknowledging various out-of-the-box issues with the all new Late 2013 iMac line, including screen flickering and audio problems.
One such document in particular describes screen flashing problems when using iPhoto print products with the new 21.5-inch, Late 2013 iMac, with Apple saying, “[the] computer may flash when using iPhoto print products in Full Screen mode.”
Apple then states (emphasis ours), “Update to OS X Mountain Lion v10.8.6 or later to address this issue. To do so, choose Software Update from the Apple () menu. Install any available updates for OS X.”
You’ll notice that the latest Mountain Lion version currently available from Apple (either as a software update from Support Downloads or on the Mac App Store) is OS X 10.8.5.
In fact, OS X 10.8.5 was just released two weeks ago, and developers are yet to report testing initiatives involving any new Mountain Lion betas.
Perhaps more interesting is that Apple also has a Supplemental OS X 10.8.5 Update prepared to address various reported bugs, making that release a better candidate for fixing the newly emerged issues with Late 2013 iMacs.
On the one hand, Apple’s OS X 10.8.6 reference could simply be a typo. On the other, Apple seemingly still has a lot of issues to address in Mountain Lion, making it fairly possible that the company’s software engineers are already beta testing an upcoming incremental update.
Apple is also known to be preparing OS X Mavericks (10.9) for release this fall. Mavericks features the first desktop version of Apple’s iBooks, Finder Tabs, iCloud Keychain, a new Safari experience, and Multi-Display enhancements, among other stuff.
