Alright so I just got my Macbook pro a few days ago(4 days to exact) for Video/Audio editing school which I start in April, but anyways, I got the mac early wanted to game, so I bought CoD4 for mac right away. Everything runs dandy besides the stupid mouse Acceleration, which I disabled with iMouseFix, but still can't seem to disable the slow down when I slow down(anyone know what I mean or how to fix?) However I've been playing CoD4 alot on PC and had my personal cfg for multiplayer, I wanted to re-create it(transfer from PC to mac), but could not for the life of me find the file location for the config. So I did some googling, some searches led to this site, acutally a lot did, but could not find the answer, as most replies where I can't find it as well. So I did some digging around and found the location: Open up Finder and go: Places/username*/library/Application Support/Call of Duty 4/players/profiles/username*/config_mp.cfg * : username is your name on the Mac I believe, its under Desktop anyways, and the second username is your profile name in CoD4. hope this helps some people.
