Just over a month after the arrival of the previous build, Apple today seeded registered members of the Mac Developer Program with the third developer preview version of OS X Mountain Lion.



From MacRumors:

The new version arrives as Build 12A178q, up from the earlier 12A154q version. Changes included in the new version have yet to be discovered, but those with access to the build will undoubtedly be searching for Apple's latest tweaks as the company continues to work on the next-generation operating system.

Apple does list a number of known issues with the current build:- On systems with FileVault enabled, canceling the restart to the Mountain Lion Developer Preview 3 Installer may leave your system unable to present a password dialog at boot time. You can repair the problem by holding down command-R to boot to the Recovery OS and then using Disk Utility to unlock and Repair your volume.
