I have an imac with a 2ghz processor and 1gb ram. UT2004 runs great on it. However, I can't find the folders labeled textures, maps, etc. in the UT2004 folder, even when I enable viewing hidden folders. I only see Cache, Saves, System, UserLogs, and Demos. So how do I install mods and bonus maps on my mac? Thanks in advance for the help.
