Hey, MayNeedsAGoodDay! Maybe today is that day!
I wanted to let you know that we have updated the OSX version of the game. It has been updated to use the Metal rendering API, be 64bit compliant, and it is notarized by Apple. This means it should run correctly now, even with Gatekeeper enabled.
If you have any more issues or the latest version doesn't seem to make a difference, please let us know so we can look into it further!
