Can you specify the issue as well as what you are doing to try to follow the instructions? I was the one who found the fix for the mac issue of the game not starting up so, maybe I can help again :)
well the first thing I tried was the chmod +x solution and turning the nwjs file and nwjs helper file into executables. I thought it worked because the game looked like it was starting but it just crashes every time.
The !zMAC USERS PLEASE READ.txt file contains all the known solutions to getting the game to work on Mac, so if nothing there works, then I'm afraid I don't know, sorry!
