We have many internally developed Automator Actions, fully #code-signed, and trusted for production use, but we have run into a problem…
On macOS Mojave, 3rd party Automator Actions must be enabled within Automator. Until they are enabled, they are non-functional in a workflow.
Automator 3rd Party Actions must be enabled, and require Admin Rights to enable. Clicking the "Third Party Actions…" button within the action, or accessing the "Third Party Automator Actions…" choice from the Automator menu brings up the following dialog.
Once enabled, the 3rd party Automator actions are visible and appear to function as expected.
The Big Question?
Is there a configuration profile that can be pushed to Enable Automator Actions from Third Parties? Or is there another method to enable this on the computer so I don't have to perform yet another manual configuration step to enable our users on each computer they use to actually do their work. The irony of requiring manual intervention to enable wanted automation…think about it Apple.
