Im not entirely sure how to help, on mac the game files are ususally compressed into mac’s equivalent of an executable, so if you can uncompress the files or open that executable maybe then you can add it to the www folder which does exist within the file somewhere. The mod will run on mac and people have gotten it working in the discord, but it is usually a case by case kind of thing, and we dont have concreate install instructions on how to get it working, sorry if thats not the answer you had hoped for.
