Hello!
I've attempted to make a macOS build of the game (if you re-download the game, there should now be a file called TheRubyCourt_v1.1.1_MacOS available.
Since I don't own a Mac, I have no way of testing it on my end, so please let me know if it works! You may have to enable permissions/admin rights in order to open the game.
Let me know how it goes!
