I am transferring from an old Macbook to a new Macbook Air. I have the The Sims 2, Nightlife, and University. I can install my games from my old computer, but how can I run my games without a cd? I have my cds and my serial codes. I have heard of a no cd crack, but cannot find one. I also tried downloading Origin, but they only go back to The Sims 3. Help!
