Welp, just to raise some hopes for y'all. Some of the volunteer devs do have a Mac, but, there is alot of paperwork (paperwork i.e Terms,Agreements,Policies n Financial Stuff) so once Dasius sorts that out we'll start working on a Mac build 😉
However a Mac build will take a while but, just as Kurzidan said, you could get a Windows PC (Desktop) for a cheap amount these days with some decent specifications. So if u have the money and don't wanna wait till a Mac build comes out, feel free to get a PC.
(We've actually tested the game on Mac aswell and the results were pretty acceptable frame-wise. But getting legal stuff done is priority, till then more optimization can be done.)
