When you run it, Windows may show “Windows protected your PC” with a “Don't run” button — that's SmartScreen's reputation check, not a virus flag (the file itself is signed and clean). Click “More info,” then “Run anyway.” This fades on its own as more people run this signed build.

We're awaiting Apple Developer Program approval to sign the macOS build, so you may see an “unidentified developer” error when opening it. Workaround: after it fails to open, go to System Settings → Privacy & Security, scroll to the security section, and click “Open Anyway” next to the Blackjack Card Counter message. You only need to do this once.
