Hi @DTS Engineer Also, we tested the package following the instructions you provided, so we completely disabled the network. Because of this, the machine couldn't verify notarization without stapling.

Hi @DTS Engineer We also ran following command and after that notarization worked: xcrun stapler staple ./test.pkg

@DTS Engineer Hello, Seems I accidentally pressed, "Accept Answer", but in reality, topic is still open for me :) Looking forward to hear your comments. Thanks, Rovshan

Hello @DTS Engineer This is what we do: # Executing the command on the machine where the notarization was performed via API Key: % sudo spctl -a -t install -vvv PackageName.pkg PackageName.pkg: accepted source=Notarized Developer ID origin=Developer ID Installer: OrgName (ID) # The same package is copied to another machine (e.g. via scp). Executing the same command on the same package on another machine: % sudo spctl -a -t install -vvv PackageName.pkg PackageName.pkg: rejected source=Unnotarized Developer ID origin=Developer ID Installer: OrgName (ID)

Follow up: # Machine where notarization is done: % sudo spctl -a -t install -vvv example.pkg example.pkg: accepted source=Notarized Developer ID origin=Developer ID Installer: company name (ABCXYZ123) # Same package, different machine: % sudo spctl -a -t install -vvv example.pkg example.pkg: rejected source=Unnotarized Developer ID origin=Developer ID Installer: company name (ABCXYZ123)
