First thing to try is moving the game to your applications folder. If that doesn't work, you can also reference this link to give the game read/write permissions. https://support.apple.com/en-ca/guide/mac-help/mchlp1203/mac (Note you may have to select which version of MacOS you are running at the top of that link.) These solutions fix that specific problem on Macs most of the time. Let me know if neither of them work for you.
