OS X 10.9.3 boosts VRAM resources on newer Macs

updated 03:49 pm EDT, Tue May 20, 2014

May help to support 4K on MacBook Pro

A subtler change with OS X 10.9.3 is an increase in the available VRAM for newer Macs, reports note. Certain machines -- including the 2013 Retina MacBook Pro, and 2013 and 2014 MacBook Airs -- now have access to 1,536MB of VRAM (1.5GB) instead of 1,024. The difference can be spotted by going to OS X's System Information pane.

Apple hasn't specified a reason for the improvement, and in fact it's completely undocumented. It may however suggest how Apple brought expanded 4K support to the Retina MacBook Pro, which isn't as powerful as the other 4K-capable Mac, the 2013 Mac Pro. That might not explain the improvement on the MacBook Air, unless Apple has identified 2013 models as a baseline.

    Twin GPUs and six Thunderbolt 2.0 ports made possible the support for three 4K displays instantly. Though, Apple is directly supporting Retina-style output on high-resolution monitors by default; but later It's possible to enable HiDPI display modes on any monitor in OS X with some quick tips.
    Apart form this goodness, re-addition of the facility of syncing Contacts with Calendar using any USB connection with an improved and reliable VPN connection in Mac and iOS devices.
