Hello, I just got my new 20" imac 2.16 GHz yesterday. I used to have a 14" ibook g4. So on my g4 i could run call of duty and call of duty united offence. Now i tried to install it on my imac and when it installs it says somthing failed. But i tried to play it anyway (multiplayer) it doesnt make any of the buttons on the menu visible. So i cant really get anywhere to play anyway. I was wondering if anyone had a fix for this problem. Ps. I also heard there is a program called rosetta that could run the game, but where would i get this if needed and how does it work. Thanks.
