Anyone have the problem of Call of Duty United Offensive on an intel iMac that will not download custom mod files or custom maps? Mine just freezes. The game starts up fine, I can search the server list easy enough but I try to join a server with a custom map its like the game just hangs then crashes a few minutes later. I have all UO ports open on my router. For reference Call of Duty 2 works perfect on this same machine with custom maps and mods.
