Signed binary being warned as signed by unknown developer on OSx
It appears the security settings of the computer in System Preferences → Security &amp; Privacy are set to Allow apps downloaded from: App Store as shown in the error message. Regardless of how your application is signed, if it's not distributed through the App Store, Gatekeeper will show that message. To allow all other signed apps, the setting needs to be changed to ‘App Store and identified developers’.
