Before signing and notarizing your built application, make sure that all of the 4D plugins (if any) are up-to-date, or else you may encounter some errors during notarization. Although 4D does sign and notarize all first-party plugins, older versions of 4D plugins may not be signed nor notarized. If an older database is being used, then the 4D plugins probably need to be updated. Also, any obsolete plugins, such as 4D Pack, should be removed before signing.

Note that third-party plugins should individually be signed and notarized by the developer. More information about that in the following tech tip: https://kb.4d.com/assetid=78592
