Hi, I'm sorry, but I think you may be mistaken. There is in fact a mac version. We outline mac install instructions in our wiki. If you need some help installing on mac please join our discord or create an issue on our Gitlab page.
I just want to be very clear there is a mac version of Crafty and based on survey responses I can tell you we have many users successfully running this on mac. I am actually one of them.
