How Do I Play On An iMac?

Does anyone have a reliable link?

I installed WINE then downloaded the windows installer.

Personally I don't play on a Mac but I know there is a download link here: https://realmserver.com/files/mac/FinvarrasFortress.zip

Anyone had any luck using the link Andris submitted above? I have a Parallels Windows 10 install going that works but would prefer native Mac if possible. The link above leads to an app that does "nothing" when opened (after moving to Applications). Update?
