by the way, i'm not saying that kitsune tails can't run on mac. it's made using FNA/SDL2, which are highly portable. ethan lee has ported our games without access to source code before, and there's nothing in kitsune tails that would make it impossible to do the same
but there's a big gulf from "this game can run on mac" to "our studio can afford to put out an officially supported mac version and offer support to users on macs and maintain it and keep it running while apple keeps trying to break it over and over and over again"
