Today, Apple has seeded the first OS X Mavericks 10.9.3 Beta to the registered developers for testing purposes. It’s not too much long since Apple released Mac OS X 10.9.2. The new beta took around only a week after the release of OS X 10.9.2.
The newly-released beta under the build number of 13D12 now can be accessed through Software Update or Mac Dev Center. The main focus of this update is towards the Graphics and Audio enhancements. This is the only thing about which we are sure as Apple asks the developers to find more about it.
We’ve seen Apple releasing OS X 10.9.2 a week ago, that included some improvements like FaceTime Audio, ability to halt annoying iMessage users on your Mac and a fix for SSL/TSL vulnerability. For your information, this update saw two months of testing before the final public release.
So, this new OS X 10.9.3 beta might or might not take more time than OS X 10.9.2. Let’s see how much time Apple takes for a final public release of OS X 10.9.3.
