We were expecting Apple to release OS X 10.9.3 this week, but instead it has released yet another beta version of OS X Mavericks 10.9.3 (build 13D61) to developers.
The new beta version arrives less than a week after the ninth beta version was released.
The release notes again ask developers to focus on Graphics Drivers, Audio, Safari, Mail and Contacts & Calendar sync over USB in iTunes. As spotted in earlier releases, the final release will likely add support for 4K displays as well as add a new “Retina” output mode for select retina MacBook Pro models.
According to 9to5Mac, Apple has already seeded a slightly newer build (build number: 13D62) to its AppleCare employees, which suggests the release is imminent. Here are the release notes for OS X Mavericks 10.9.3 update according to 9to5Mac’s source:
The OS X Mavericks 10.9.3 Update is recommended for all OS X Mavericks users. It improves the stability, compatibility, and security of your Mac.This update:
Improved 4K display support on Mac Pro (Late 2013) and MacBook Pro with 15-inch Retina display (Late 2013)
Adds the ability to sync contacts and calendars between a Mac and iOS Device using a USB connection
Improves the reliability of VPN connections using IPsec
Includes Safari 7.0.3
Apple has also seeded Safari 7.0.4 to developers. However, it is not clear what’s new in the Safari update.
Apple last public release was OS X Mavericks 10.9.2, which debuted in February and included a fix for a critical SSL bug, along with other bug fixes and performance improvements. It also enabled an audio and video call waiting option for FaceTime and added the ability to block incoming iMessages from individual senders.
