I am packaging an app with QtWebEngine in it, after codesign the app and the QtWebEngine Framework, the app can run properly. The codesign result is: valid on disk staisfies its Designated requirements Then I notarized and stapled the dmg file, after the dmg installed on Mac, gatekeeper still failed the check. Here is the result for spctl: spctl -a -t open -vvv --context context:primary-signatue Remote\ Graphics\ Workstation_.dmg Remote Graphics Workstation_.dmg: rejected source=Insufficient Context Need help to identify the codesign process and the root cause why gatekeeper fail here, thanks.
