Following its latest seed of OS X Mavericks 10.9.3 beta (build 13D17) to developers, Apple has just pushed out a newer pre-release version of the 10.9.3 beta to employees alongside a pre-release version of iTunes 11.1.6 beta.
The new pre-release of OS X 10.9.3 (build 13D19) is available to employees and doesn’t introduce any major changes since the latest beta build seeded to developers. The last beta release asked developers to focus on testing graphics and audio drivers.
iTunes 11.1.6 brings fixes for the latest 10.9.3 builds and “restores the ability to sync contacts and calendar information to your iPhone, iPad, or iPod touch from your Mac running OS X 10.9.3.” The ability to sync contacts and calendar data to an iOS device from a Mac was removed previously (to many complaints) but remained possible through iCloud syncing.
The final release of 10.9.3 could bring at least one new notable feature for users: support for driving 4K displays at Retina resolution and 60Hz output from 2013 MacBook Pros.
