Hi Guys I'm in the proccess of saving up for a Mac and Pro Tools for university (going to study music production and film scores). I was wondering if I bought one copy of pro tools, would I be able to install it on the Mac and my PC or would I have to buy two licenses? Also, should I go for a Mac book Pro 15inch with a 2GHz or 2.2GHz. does the 200MHz really make much of a difference. I know it wouldn't in a PC case but I'm a bit of a newbie to the Mac world. TIA George
