If you notarize Mac software with the Apple notary service using the altool command-line utility or Xcode 13 or earlier, you’ll need to transition to the notarytool command-utility or upgrade to Xcode 14 or later. Starting November 1, 2023, the Apple notary service will no longer accept uploads from altool or Xcode 13 or earlier. Existing notarized software will continue to function properly.
