If you’re hesitant about updating to the recently-released OS X 10.9.3, there may be good news if you’re a recent Apple notebook owner.

Per French news site Mac4Ever and MacRumors, updating to 10.9.3 increases available VRAM from 1024MB to 1536MB, boosting the size of the shared memory, possibly to further improve 4K performance on the most recent Retina Display MacBook Pro and MacBook Air notebooks..

The change can be seen in the Graphics/Displays section of the System Report accessible via “About This Mac”. Apple has not yet updated its support page to reflect the new VRAM limits, continuing to list 1GB of system memory as the maximum. The update was also not mentioned in the 10.9.3 release notes.

The 10.9.3 update also included enhanced support for 4K displays and restored the ability to sync contacts and calendars between Macs and iOS devices over USB.

Finally, it’s been reported that some machines with HD 4000 graphics have seen a VRAM boost as well, namely the 2012 Mac Mini, which now has a maximum VRAM of 1024MB, up from 768MB.

If you’ve seen this improvement or any significant changes on your end since installing OS X 10.9.3, please let us know in the comments.
