Google Analytics can sometimes reveal some interesting information as tech website Cult of Mac discovered. The news website (opens in new tab) managed to track Apple's followup to its current Lion OS, Mac OS X 10.8, in its analytics logs.
Interestingly, Apple seems to have been testing OS X 10.8 since earlier this year but it appears to have become more common only a few weeks ago, meaning a more widespread phase of internal testing.
Cult of Mac reckons that Apple may call the next version of Mac OS X, Manticore, although there's a growing number of its users who want it to be named Sabertooth.
Apple released Mac OS X Lion back in July 2011 which was first unveiled at Apple's "Back to Mac" event in October 2010.
Lion was the first Apple OS that adopted a number of iOS features like a navigable display of installed applications and support for Mac App Store.
It is also the first mainstream OS that is primarily distributed as a download via Mac App Store. Users can also download it instore from Apple Stores or as a $69 USB Flash drive.
It is likely that Mac OS X 10.8 will be closing the gap even more between the desktop Mac OS X and iOS 5. Expect the update to be released sometime towards the middle of next year.
