Apple releases OS X 10.9.3 update with improved 4K support

Apple has released an update to OS X Mavericks that brings the version number to 10.9.3. The update is now available to download through the Mac App Store.

One of the major changes in this update is improved support for 4K monitors. What this means is that now if you connect a 4K monitor to a compatible Mac (the 2013 Mac Pro or the 2013 MacBook Pro with Retina display) you will get the HiDPI ‘Retina’ option instead of standard 1:1 scaling. This results in sharper images but at the same time, the onscreen items are now larger and easier to see. This is similar to the way scaling works on the MacBook Pro with Retina display. Also, the 4K output now supports 60Hz refresh rate for monitors that can support it.

The other changes include:

  • Ability to sync contacts and calendars between a Mac and iOS device using a USB connection
  • Improves the reliability of VPN connections using IPsec
  • Resolves an issue that prevented Font Book from installing PostScript Type 1 fonts
  • Improves reliability of copying, editing and inspecting permissions of files on an SMB file server
  • Improves reliability of network home directories
  • Improves stability when installing configuration profiles
  • Improves login speed for users in Active Directory groups
  • Includes Safari 7.0.3
