Registered mom and dad developers, fire up the Mac App Store and click “Update,” because Apple has a fresh Mountain Lion developer seed — OS X 10.8.3 12D50. Of course, you will need Apple’s OS X Software Update Seed Configuration Utility, but what else is new?

About two weeks ago, Apple released OS X 10.8.3 12D44, which arrived with no known issues and a note from Cupertino’s software simians that devs should focus on AirPlay, AirPort, Game Center, Graphics Drivers and Safari.

That said, according to our friend and informant Scruffy, some devs that have set their screen saver to automatically run under OS X 10.8.3 have indeed found themselves focussed graphics drivers — moof!

What’s new in 12D50? Apple advises that there are no known issues and devs should focus on — wait for it — AirPlay, AirPort, Game Center, Graphics Drivers and Safari.
