I am using my Developer certificate to sign Automator Apps via the Export dialogue, however when distributing these apps (outside the Mac App store) via email, Gatekeeper still flags my apps as a from an unknown developer. I gather from the Apple Developer forums that non-App store apps are tagged with a quarantine of some sort.

I am hoping to see if someone else has encountered a similar issue and found a workaround. Perhaps an Applescript I can add to my workflow that will remove that quarantine?


Signature Check

Check your Automator application is being signed correctly. Do this using the command line tool codesign. Use the following command in Terminal.app to view the code signature associated with your application:

codesign -d -vvvv /Applications/MyGreatAutomator.app

Does the output mention your developer identifier? If not, revisit how you sign your application as it may be broken.

Quarantine Flag

The quarantine flag is applied to files downloaded from the Internet. This flag can be manually removed using this command:

xattr -r -d com.apple.quarantine /Applications/MyGreatAutomator.app
