Apple has made the OS X 10.9.3 update live just a few moments ago and the top enhancement within the release notes is expanded 4K display support, although this has been known for a little while thanks to the normal month of testing before software updates become available.
If you have already updated to Apple’s Mavericks OS, then you can download the OS X 10.9.3 update today. The improvements launching today follow two other major updates, and the latest update to the OS features many enhancements, bug fixes, and patches to the security.
Both the 15-inch Retina MacBook Pro and Mac Pro from 2013 improves on display for a 60Hz refresh rate on supported monitors and use the HiDPI Retina scaling mode. The update also includes Safari 7.0.3 and gives users the ability to sync calendars and contacts between iOS and Mac using USB.
