Hmmm.  I have not tried a restart.

They are not.

Tried it anyhow.  Result:

    Command is not yet implemented.

After all that, I tried a restart, launchctl uncache and launchctl remove again.  Result: No change.

I also counted the number of disabled services my app has using "grep -c".  Result: 3060.  That’s three thousand sixty.  Eeek.  What are these doing?  How can I remove them?
