Hi, I just switch to a Mac, I have found that a lot of games that I want to play now are Windows only(not that I could run them on my old PC anyways, due to no RAM and administrator Permission on my user), I would be willing to try to schedule a date to let you remote access my computer to make a Mac port, if it means more games like this can come to macOS!
Edit: Idk if Itch will notify me so you can use the info on the contact page on my website just incase, you don't have to follow the instructions on the page, just message me, tell me from Itch, tell me the name of this game and I should remember, and then I can try to find a time that I'm available to let you use my Mac!
