I have the same issue on my 2012 15" macbook pro. Every time I switch to mayor mode, my game freezes and I have to force quit. Its a shame because it seems like every mod I want to download requires it as a dependency. It downloads as a .dat file,, and file juicer doesn't really do anything when I drag the file into it. Hamish, or anyone that may know, how can I fix it? Whenever I try to extract it using another program, it opens in MPEG Streamclip and says file not supported and other crap like that. Is there a way I can get it to work, or will Gizmo's mod suffice? I doubt it would, but still, any help would be greatly appreciated.
