That's unfortunate, can you send us a message on our website? We currently don't have a physical Mac computer to test with, which makes things difficult.
Edit: Seems to be an issue on M1 Macs.
found the problem, also found a solution, when downloading something through safari, when that file is downloaded its auto extracted, which in some cases can corrupt the download, it then dumps the zip into the bin, what you need to do is delete that extracted file, and move the zip from the bin back into downloads and extract it manually, you'll see that when you extract it manually the icon should be a vial with some pink fluid, theirs nothing wrong with the game, its something about apple
