i have a macOS app that uses Game Center. how do i make it available to beta testers?
i understand that TestFlight is available to developers running macOS v12. but my testers are normal users who are running macOS v11.
my first thought was to sign with a Developer ID and let testers download the app. except that Game Center is not supported in Developer ID apps. Can I sign and upload to App Store Connect and somehow offer the binary to testers?
