I followed the guide at http://macperformanceguide.com/SnowLeopard-64bit.html to boot into 64-bit mode. I had no problems with the instructions and on the boot screen it says "PAE enabled, 64bit mode enabled" but when the system boots, both uname -a and System Profiler tell me that it has booted into 32-bit mode.
I really need to boot into the 64-bit kernel, what should I do?
System is MacBook Unibody (Early 2009, 6 GB RAM, 2.4 Intel CPU, 10.6.6)
