Mac OS X 10.9.3 brings improved 4K support to Mavericks

Fire up the Mac App Store, people, Mac OS X 10.9.3 is now available. The update brings a handful of improvements to Mavericks, including 4K display support for the new Mac Pro and late-2013 MacBook Pro laptops. Also included is the ability to sync contacts and calendars with an iOS device over USB (or, you know, you could just use iCloud or any other cloud service).

Additionally, 10.9.3 improves support for VPN connections using IPsec and comes bundled with the previously-released Safari 7.0.3.

The Mac OS X Mavericks 10.9.3 update is available now via the Mac App Store. It's a heavy update, weighing in at 461MB on our retina MacBook Pro, though your megabytes may vary.

Mac OS X 10.9.3 brings improved 4K support to Mavericks


Just installed it on iMac. My eyes are probably playing tricks on me but fonts and pages seem sharper. Install was fairly uneventful except had to force quit the mail app. Regarding mail I think it needs some work. When I delete on iMac not all the inboxes go to trash across devices. Unless I have the settings ass backwards, Comcast mail is the culprit. It is a pain to clean up the folder on one device and then have to go through the same crap again on the others. So not sure what to think. So does Mail still need some work or is it just me?

I updated my Mac mini, but haven't looked at it yet. I'm connected to a 27" 2560x1440 via miniDP-DP.

My question to you (might answer before I get home) are there new scaling options in System Preferences under Display?

I assumed these options would arrive to non-"retina" stamped devices by at least 10.10 this would make my eyes happy when kicking back in my chair.
