How to run the demo on a Mac and probably the full game too

[jim]

I have the demo running smoothly on my 2017 iMac. Here's how:

1. Go to https://www.portingkit.com and download Porting Kit. It's free.
2. Run Porting Kit and click on All Games on the left, then search for Steambuild 32/64bit DXVK.
3. Install it. You now have the Windows version of Steam on your Mac.
4. Run it and log in with your Steam credentials.
5. Download the demo and enjoy.

It works perfectly for me, so I am likely going to buy the full game.

Of course, you aren't limited to just the Against the Storm. You can download any game on Steam, however not all of them will work. Porting Kit provides customized, tested ports for hundred (thousands?) of specific games, especially older ones. It's pretty cool.
