Would like to play, but the Mac game file doesn't work
Your Mac build does work, but it's not notarized. Apple wants users to only trust Apple's App Store so when you open an unsigned application macOS acts like it's scary/broken/untrustworthy. You can force it to run anyway, and I left a comment in this thread with the steps.
If you want to make an app that "just works" on Macs, it needs to be notarized. RenpyTom has info about that here. https://patreon.renpy.org/macos-notarization.htmlUnfortunately that process needs a Mac. A not-notarized app is definitely better than no app though. Game runs great once you bypass the checks.
Oh and I really like the game too BTW. Nice work!
The Mac version does work, but it's not signed by Apple so you have to do a one-off security override to make it run. If you're not comfortable with that it's best to stop here, but I think it's fair to say the risk from a Renpy game is very low. YMMV.
The steps below will add an exception for the game executable to allow it to run. It doesn't disable any macOS security checks.
1) Try to open the game will say it can't because the developer isn't verified. Click "cancel", not "Move to bin".
2) Open system settings, and go to "Privacy and security". Scroll down and you will see a message that "AIRevolution was blocked because...". Click the "Open anyway" button.
3) macOS will ask for your fingerprint or password. Do this.
4) macOS will then once again ask if you want to open the game and warn you about security and malware. Click "Open", and the game will start.
This exception will be remembered so next time you open the game it will start normally without any warnings. When a new version comes out however, you will need to go through these steps again to add a fresh exception.
