It seems fairly certain that OS X 10.9.3 will arrive this week, perhaps as early as Tuesday. It is also rumored that OS X 10.9.4, which could be the last Mavericks update, testing has begun internally at Apple.
When it comes to new features, OS X 10.9.3 offers support for pixel doubling scaling (ie Retina) output model for late-2013 MacBook Pro with Retina Display models. Apple has also added support for high frame rate QuickTime and QuickLook slow-motion playback.
There are also a range of bug and feature tweaks baked into OS X 10.9.3, including the return of iPhone/iPad syncing in iTunes.
9 to 5 Mac’s Mark Gurman is saying that OS X 10.9.4 is now testing internally at Apple. Codenamed Epic, little nothing is known about this Mavericks update.
However, if past is prologue, OS X 10.9.4 beta testing will begin about a week after OS X 10.9.3 ships.
Also, it is widely believed that OS X 10.10, a major visual recoding of the Mac operating system experience, will be introduced at WWDC 2014 in about a month…
Feeling good about the Mac and Apple’s desktop direction?
