12d61Apple today seeded build 12D65 of OS X Mountain Lion 10.8.3 to developers, marking the ninth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November 2012.

Build 12D65 comes exactly one week after build 12D61. As with build 12D61, build 12D65 continues to ask developers to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.

Registered developers can download the update on Apple's Developer Page.

Update: According to 9to5Mac, the new build fixes the file bug that recently made headlines.

This post originally referred to Build 12D65 as the tenth developer seed of OS X 10.8.3 when it was actually the ninth seed.

Shutdown times appeared faster a few builds back, but seem slow once again. Although, they don't appear to be as slow as 10.8.2.

I'm seeing a few new bugs I haven't seen in previous builds.
I had duplicate cursers on my screen a moment ago.
Every time I log out, the desktop picture freezes in the middle of fading to the fabric background of the Login Window. Very jarring.

File a bug report.

I hope that after they release 10.8.3, they release an update to Bootcamp so I can install Windows 8 (with full support).
