I'm not able to test it as I don't have a Mac. I would assume so because it's a gamemaker project (and I'm also assuming that Mac Gamemaker use the same file formats). If you buy it and have problems, let me know though! I'm sure you can refund via Itch also.
ahaha thx for your reply. I just bought your whole 2D RPG kit and plan to study the codes along with your tutorial videos. Thanks for your contributio! It is a wonderful work!
