Thanks for the replies. You are both quite right that I should have provided more information. When I say that notarization succeeds, I mean that I submit the dmg file produced by the build to the Apple notarization service and receive a status of 'Accepted'. I take this to mean all is well. When I say that notarization fails, I mean that the notarization step produces a status of 'Invalid'. Retrieving the notarization log indicates that the binaries were not signed. I've just gone through this again with my two machines. The build here is performed by scripts that are maintained in source code control and forced to be identical in both setups. The build infrastructure is also the same for both. Before beginning, both machines were powered off for a period of time. Power up one machine. Ensure the source tree is up-to-date. Run the build to produce a signed dmg. Submit it for notarization. The submission produces a status of Accepted. Power down the first machine. Power up the second machine. Again ensure the
