Apple seeds eighth beta version of OS X Mavericks 10.9.3 to Developers

osx-mavericks-10-9-3-beta7

Last night, Apple seeded the eight beta version of OS X Mavericks 10.9.3 (build number: 13D45a) to developers.

The new beta version arrives less than a week after the seventh beta version was released.

Apple has requested developers to focus on Graphics Drivers, Audio, Safari, Mail and Contacts & Calendar sync over USB in iTunes for this build as well. So far, developers have discovered native support for 4K displays in the first beta version of OS X Mavericks 10.9.3. The update will enable HiDPI “Retina” scaling on 4K displays, which is not supported natively. You have to use a workaround to enable HiDPI display modes on any monitor in OS X currently.

Apple had released OS X Mavericks 10.9.2 in February, which included a fix for a critical SSL bug, along with other performance improvements. It also added a call waiting feature for FaceTime audio and video calls, and the ability to to block incoming iMessages from individual senders.

Apple had released six beta versions for OS X 10.9.2, so I expect Apple to release OS X 10.9.3 very soon.

Please let us know if you’ve found any other change in the comments below.
