There's no official plan for native Mac or Linux support. With that said, the game is Steam Deck verified, and you may have good luck on Linux with Proton in general. I've also heard some people have good luck with Crossover on Mac as well, but I don't own any Mac hardware and have not done any verification testing there. If you are interested in pursuing one of those options, then I'd advise getting the game on Steam instead, since the refund policy there is more straightforward. :)
