Apple Updates OS X Mountain Lion Developer Preview to Build 12A206j

Apple pushed out another update to its OS X 10.8 Mountain Lion developer preview program, moving to build 12A206J.

Apple notes that "MacBookPro3,1", which corresponds to mid and late 2007 machines, is not compatible with the new build because of an issue that was reflected in a later build of the OS.
No other details on improvements in latest build are available yet, but certainly appears that Apple is making some of its final tweaks for developers leading up to its WWDC, which is less that four weeks away. Apple is also expected to provide previews of OS X Mountain Lion at the conference and with a public launch scheduled for "late summer".
