Mac Gaming Mods

are ther any mods with misions for cod 1 and uo.
i found pc mods with misions but dont know how to start them! Plz help me coz playing same misions on cod and cod uo 10 times is boring!

The PC missions should work on a Mac since the PC mods work. You should be able to start the new maps using the console. Go into the console and type 'map <mapname>'.
