I just installed 10.8.2 onto a fresh drive on my Mac Pro 3,2 18GB Ram, 2x2.8GHz Quad. Everything is great EXCEPT I can't get the Kernel to run in 64-bit mode. My old 10.6.8 is still available and so I booted to that, and was able to run in 64-bit just fine. Also odd is that there is no information in the System Profiler under System Software Overview...where it should say 64-bit Kernel and Extensions [yes/no], there is no line at all (there is in 10.6.8). I am using that little Startup Mode Selector App to see if the kernel is in 32-bit.


Kernel Version is Darwin 12.2.0


I am stumped...



Mac Pro, OS X Mountain Lion (10.8.2)
