I'm looking into my error reports and it seems to be an issue with the mac not having the permission to access the files.
Could you try changing your permissions on the game app to enable "Read and write"? Right click on the game app (THJ1.2Mac.app) , select "Get info" and you'll see a window like in the image. Click the lock icon and then change your permission to allow "Read and Write".
Let me know if that helps!
