Earlier this year Apple announced the next chapter in its Mac OS X operating system. The 10.8 update, also called Mountain Lion brings in a lot of new features for the Mac lineup. This includes Facebook integration, power nap for the SSD equipped MacBooks and deeper iCloud integration. The Mountain Lion update has been successful as no major issues have been reported. However that won’t stop Apple from preparing the next update.
Apple has not mentioned any plans of a successor to Mac OS X 10.8 yet. But in the last few days some websites are reporting traffic coming from OS X 10.9. This includes Apple Insider, which reports that nearly 30 visits from OS X 10.9 have been made in the last few days. Other websites are also reporting the same thing. Someone from within the Apple labs is evidently testing out an early built of Mac OS X 10.9.
While something like this can easily be faked, this looks legit since its on multiple websites. As mentioned before, nothing about OS X 10.9 is currently known or when we can expect it. Apple usually brings in major updates to OS X on annual basis so we should expect OS X 10.9 to hit somewhere around June 2013.
