3. Run all apps (a hidden setting)
The default is 2 and you can achieve 3 (even when 2 is selected) by right-clicking and selecting Open on first-launch.
This change relates only to 2. "signed by a Developer ID" is being replaced by "signed and notarized by a Developer ID". This change applies immediately to developers who have never released a Developer ID app and will apply to all Developer ID apps in a future release of macOS.
