That’s right, I said PRO. As in, the full version of CrossOver Mac, which includes CrossOver Games. It also includes 12 months of support at Level 2, and the ability to renew support every year for $35 (or free if they ever have a promotion like this again). This is a $70 value, for $0 and you really can’t beat that. But remember, you have until 11:59 PM (23:59) Central Standard Time to sign up and use your free serial key to authenticate. The serial keys will no longer be good after that time, so go do it now.
