I know one can turn the finder and OS to 64 bit, by holding down the 6 and 4 keys during boot up. But, how can one do it the other way around (I'd like to simply try it again, since I am getting HUGE memory usage on my 4GB MBP) I have tried holding down the 3 and 2 keys upon boot up, but that doesn't seem to work?
Any other tips?
