[quote='820155021, alex_strong, /thread/820155, /profile/alex_strong'] I've had issues getting the dmg signed by the Apple notary service [/quote] That text suggests that you’ve misunderstood how notary works. The notary service doesn’t sign your product. Rather, you present it with a distribution-ready product, one that’s already signed, and the notary service checks it and, if all is well, issues a signed ticket. See Notarisation Fundamentals for more about how this process works. As to why the notary service is refusing to notarise your product, it’s hard to say without more info. It sounds like you were able to submit the product and get a response, but the status is Invalid, indicating a problem with your submission. In that case the next step is to look at the notary log. What does it say? See Fetching the Notary Log for info on how to get the log.
