It seems that with the new system used to protect the archives the MAC version does not work anymore. I will make it unavailable until I understand what is going on.

I don't have a Mac so it may take a little time.

My apologies for the inconvenience 

[EDIT]

The game on Mac works perfectly after verification, please make sure your Mac is up to date and allow the launch of unverified applications that can block the launch of the game
