I might be late to the party, but I tried following your steps and your chameleon settings, just freezes constantly. I'm talking about only a couple of seconds to do something before the system freezes. What could be the problem?
My specs: osx 10.7.5, i5-2500, 16gb ram, ga-p67a-ud3 board (something like that), 620w psu, msi radeon 6850hd (formerly had a 6670hd 1g d5 worked good).
Help!
