Apple has issued its long-awaited OS X 10.9.3 update, after a rather lengthy time in testing. This update improves support for 4K displays, which will allow for Apple’s HiDPI scaling, such as that used for its Retina MacBook Pros, to be used for these displays.
Specifically, the update includes the following enhancements and fixes the following issues:
- Improves 4K display support on Mac Pro and Retina MacBook Pro (both late 2013 models)
- Adds ability to sync contacts and calendars with iOS devices using a USB cable
- Imrpoves the reliability of VPN connections using IPsec
- Includes Safari version 7.0.3
This update is available via Apple’s Software Update service, which is accessible in the Apple menu, and while recommended to install, you might wait a short while before installing it, to ensure there are no bugs that made it through testing.
As always, be sure you fully back up your system before applying this or any other software update.
