I don't currently have Mac builds because I read the Godot docs page for it and saw that there was a lot more to it than just changing the export target. But I just looked again, and apparently you don't actually need to do most of that! So no guarantees, but I'll have another look at it for the next update (I'll have another look at getting Linux builds working too while I'm at it, would be cool to add both at the same time). Just be aware that if I do get them working, totally a chance there's bugs since I don't have a Mac to test it (same for Linux builds)
