I'm not quite sure what's so Mac or Linux friendly about this game, since in the download, the only obvious executable things in it are .exe files which are files windows can run, not really what mac or even linux can run. While yes, it CAN be run on Mac or linux using wine, but that's not really something I would consider "friendly" or easily accessible for these platforms, adding the fact that you never really even mentioned wine in the first place so any normie mac or linux user would be dumbfounded to see that the game they downloaded and expected to instantly play was a game they couldn't even run. I recommend removing the mac and linux on the available platforms list until there's a valid executable for each platform.
