Hey Mark,toggle quoted messageShow quoted text
I can't speak to what might be the problem, but I've been reading about code signing and notarization recently in an effort to better understand how it all works at a lower level, so I'm interested in what you find out.
TN2206 (https://developer.apple.com/library/archive/technotes/tn2206/_index.html) makes reference to using the `check-signature` tool (https://developer.apple.com/download/more/?=SignatureCheck) to validate package signatures. Have you tried that? Does it report anything useful?
