Apple Inc. (NASDAQ:AAPL) released OS X 10.9.3, a major update to its Mavericks operating system for Mac computers, on Thursday, following weeks of extensive beta testing.

The latest Mac OS update, which is now available for download through Mac App Store, brings high-resolution 4K display support for the latest Mac Pro and 15-inch MacBook Pro while also improving the stability, compatibility and security of the operating system. According to Apple, the OS X 10.9.3 update is recommended for all Mac users.

Thanks to the new update, owners of the Mac Pro and the MacBook Pro with 15-inch Retina display will be allowed to connect their computer to an external 4K monitor and take advantage of refresh rates of 60Hz. The new OS X 10.9.3 will also use the pixel-doubling technique to allow for a true Retina experience where the size of user interface elements such as windows, icons and apps remains unaffected, iDownloadBlog reported.

In addition to the display improvements, the update also adds the ability to sync contacts and calendars between Macs and iOS devices using a USB connection and improves the reliability of Virtual Private Network, or VPN, connections using Internet Protocol Security, or IPSec. The update also includes Safari 7.0.3.
