Apple has seeded a new beta of OS X Mavericks 10.9.4 to developers for testing. The pre-release software has the build number 13E16 and is available through the Mac Dev Center for download. The accompanying seed notes do not reveal any notable changes to the Mac software, as was the case with the first beta released last month.
While it remains unknown what features or changes that Apple has made in OS X 10.9.4, the beta version likely contains bug fixes and other minor improvements. It is unclear when Apple will release the software update to the public, but I anticipate that it will be seeded in a matter of weeks or sooner.
Last month, Apple released OS X Mavericks 10.9.3 with improved support for 4K displays on the Mac Pro (late 2013 model) and 15-inch MacBook Pro with Retina display (late 2013 model).The update also added the ability to sync contacts and calendars between a Mac and iOS device over USB, improved the reliability of VPN connections using IPsec and included Safari 7.0.3.
While beta testing continues for OS X Mavericks, the software version is largely overshadowed by its successor OS X Yosemite. Apple took the wraps off OS X 10.10 at its WWDC keynote last week, with new features ranging from a completely redesigned user interface and stock apps to improved Spotlight search and Continuity. OS X Yosemite will be publicly released in the Fall.
Apple also seeded new builds of the OS X Server 3.2 and Safari 6.1.5 betas to developers.
