Hey guys, I have a late 2010 MBP and am trying to boot into 64bit. I have held down the "6" and "4" keys while booting but am still coming up with "64-bit Kernel and Extensions: No" when I check in the system profiler. I had no problems booting into 64bit with my early 2008 MBP. ANy suggestions? Oh, and I am on 10.6.6. Thanks!
