I bought CS5 Master Collection JUST so I could have After Effects CS5 for school. I have a mac mini w/snow leopard that I can NOT get to boot with 64 bit capability. I need help. I did the 6 and the 4 hold down which some of you say worked for you. No go here. Can anyone help me please?? I spent alot of money and would've just stayed with CS4 if I knew about this hassle before hand. Seems like SOMEBODY at Adobe coulda mentioned this problem.... and WHY is there a 32 bit support workaround for Windows only???
