Is there no way to “empty the trash”?
Disabled job entries are stored in a dictionary, so the fact that you have thousands of unique entries makes me think you've hit a pathological condition. In this case, launchd is honoring its contract. Someone previously disabled a job of a certain name, and the expectation is that future attempts to load a job of that name should fail. There's no garbage collection policy. If there was, someone other than you would very likely complain that the system is not behaving as advertised. -damien >> It's a switch in terminology, but not as radical a change as you might fear. >> A "service" in launchd refers to anything that is a daemon, agent, or XPC >> service, that is, anything launchd can load and manage.
