How do I verify that a macOS installer pkg file has been notarized? Is there a way to do it via the command line?
stapler validate will do this -
$ stapler validate myfile.pkg
Processing: myfile.pkg
The validate action worked!
If The validate action worked! is printed, the specified pkg file is notarized.
If does not have a ticket stapled to it. is printed, the specified pkg file is either not notarized, or the notarization was never followed up with the stapling step.
