I got the link no problem as well.
I was able to download the Mac version of the game but I think it is refusing to load due to thinking it might be malware so I can wait until it gets fixed.
Viewing post in A topic to verify that your copy of the game works!
Just managed to get my mac friend to run it. We don't have official apple certification so when you first launch the game it will say that it can't verify it's malware free - if you go to Privacy and Security it will mention that it blocked the app and you can then tell it to open anyway. (This was with downloading and running it directly - I don't know if it works differently if you try to run it through the itch app.)
