I click on "about this mac" and im told that it will display what bit mode i am in, but it doesn't. I saw a youtube video that said to switch from 32 bit to 64 bit you simply press and hold the 6 followed by the 4 during boot up and that switches it. I tried that and my screen sat endlessly on a blue screen for as long as i held the 6 and 4 keys down.


Can anyone tell why it is so stupidly difficult to find info on this subject? Even typing into the help on my imac "64 bit" comes up with nothing. Like, seriously?


I've just installed mountain lion because i want to purchase Logic Pro X, which will only run in 64 bit mode, but i can't even see what bit mode my system is currently running in.......

iMac, OS X Mountain Lion (10.8.4), Intel i5 2.66ghz Quad core
