Hello.

I would like to report that the version displayed on the game page is incorrect.
I have macOS version 10.12.6 installed and I can't play. The minimum version for this game is now macOS 10.14.
It would be great to have the older version available for download for true old gamers with old machines.

That's just not how code works. You'd simply be robbing yourself of new features if you stayed on an old version, as it isn't a static game like X-Com.

Sorry that you bought into a system with a forced obsolescence policy, though.
