You need to "show package contents" on the app, go into "Contents" and then "MacOS". Now type "chmod +x" in terminal, and drag the "Femdom Wife Game - Zoe" file into terminal - this will copy the path to the file that needs to be targeted. now run the command. I have to do that every new version, and it always gets it running.
This Is often an issue with a lot of Indie game devs who don't have Mac's to Test on, the unix executable file in the app package ends up as plain text. It's some sort of issue/error within unity itself, not sure if bug or just like multiple extra steps for the mac version that aren't intuitive at all. I wish it were clear what the it was either way though, maybe it could be avoided.
