Your Mac

Automation

These run on their own, on a schedule, whether or not anybody is watching. This page is the only place they have ever been visible.

What passed means, exactly. The job told the scheduler it finished without an error. It does not mean the job did the right thing, and this page will not claim that it did.
What not yet seen means. The job has not run since this Mac last started, so there is nothing to report. That is a different fact from passing, and it is never shown as one.
