the mac version seems to have a glitched out background, is that part of the game?
Late reply, but I finally got a Macbook to test on. I'm pretty sure the problem you experienced was just due to that particular build being corrupted. It should work correctly now (2.1.2). There were other graphical issues that have been fixed as well.
Keep in mind, the game might run slowly on the Intel UHD Graphics series and/or an i5 CPU. It works for me on a 2014 (?) Macbook Pro with an i7 and Intel Iris series integrated graphics. Either way, you can try it and see how it runs.
