Hello and thank you! The newest version of Mac requires game devs to fill in some paperwork and pay a yearly tax... which I'm sorry to say isn't worth it with the little number of downloads from Mac users I get. I know many Mac users do some kind of trick in order to be able to overcome this inconvenience and download indie games anyway, so they can play the itchio version. However, Steam doesn't even allow me to upload an old Mac version, so the game will only have a Mac build for itchio.
I can make a post asking about how to bypass Mac's features and play indie games on your computer, if you want.
