Already talked to you about this over Discord, but for anyone looking for an
unofficial way to run on Mac, I got it working on 1.17 by downloading the Windows version and running it through PlayonMac and creating a custom shortcut.

The game runs fine for me, but just a reminder that 1.17 has some bugs that still need to be sorted out, so do not fret if this method does not work well!
