Apple releases beta build 12D74 of OS X 10.8.3 Mountain Lion with no known issues

Apple on Thursday seeded build 12D74 of its OS X 10.8.3 Mountain Lion update to developers, the latest in a string of betas since the first build was released in November of last year.

Build 12D74 comes weeks after Apple released the tenth beta earlier in February, which resolved an obscure detection bug that caused many OS X apps to crash when the phrase "F:///" is typed into a text field.

People with knowledge of the beta have informed AppleInsider that, as with the past few beta builds, the most recent comes with no known issues and asks developers to focus on the same five areas: AirPlay, AirPort, Game Center, Graphics Drivers and Safari.

The news comes on the heels of a continued reports of increased traffic from Macs running the as-yet-unannounced OS X 10.9, which suggests an unveiling of the next-gen operating system could be imminent.

While the latest seed comes more than three months after developers first began beta testing OS X 10.8.3, AppleInsider traffic logs are already showing the presence of Macs running an OS X 10.9, suggesting an unveiling could occur soon. Apple first announced OS X 10.8 Mountain Lion over a year ago on Feb. 16, 2012.
