Hey hey! Sorry to hear that >.< Mac is always really awkward, unfortunately :( It's possible there's a problem because I renamed one of the files after export, so I've just reuploaded the Mac version with the original file name it came out with upon export. You can try downloading again to see if that makes any difference, but it probably won't T_T
Here's a big list of help I've compiled for Mac users: https://melancholy-marionette.itch.io/darling-duality-winter-wish/devlog/227880/...
It's posted on one of my other games, but the info there applies to all of my games. It's a mixture of tips other Mac users have told me about once they've managed to get my games working + some general stuff I found when I searched online a while back :3
Hopefully, something on there will help you! Unfortunately, I don't own a Mac or know anyone who does, so I have no way of testing Mac builds myself. From what I understand though, the main reason my stuff doesn't open on Mac without fiddling with things is cos of the extra security that Mac devices have. I've been told it's because a lot of indie games get blocked by the security because they're unsigned or something >.<
