“Another beta version of OS X 10.9.3 has been released for registered developers, indicating that it shouldn’t be too long until the general public can get its paws on the updated Mac OS software,” Joe White reports for AppAdvice.
“Though OS X 10.9.3 might sound like a minor point update, for certain users it’ll prove quite significant,” White reports. “This is because OS X 10.9.3 brings ‘true’ Retina display support for external 4K monitors.”
“In OS X 10.9.3,” White reports, “MacBook Pro with Retina display owners can run external 4K monitors at pixel-doubled ‘Retina’-grade quality resolutions. Plus, we’ve also heard from registered developers that the updated software allows users to power 4K monitors at 60 Hz, rather than 30 Hz, which should result in a smoother experience.”
