OS X Mountain Lion Developer Preview two 12A154q | 3.43 GB
This is the 2nd developers preview
I tried it and installed just fine either on top of the 1st preview or burned on a dvd and instal alone
Checksum for the dmg is : 85a834c08706ff8d6ac92328c6bd6e1f
Please check yours as well to make sure its a match if you having a problem
