Maybe I'm too dumb, but I haven't figured out a good way to sign just a binary (or a tar/zip containing a few binaries). I zipped up the binaries, sent them off to Apple, Apple comes back and says "yup, notarized!", and they still trigger the popup. I'm probably missing a step. I guess I'm not currently stapling the ticket to the binary, but supposedly you don't have to if you are running with a network connection.
