> In particular, the service launcher (launchd, mentioned in the article), and various other system level things (including logs, also mentioned in the article), have so little official documentation as to be laughable. I've filed documentation bugs against launchd. They acknowledged the issue, and then filed them for resolution in the n+2 major release in macOS, because it was too late for the next major release. I suspect their technical documentation process to have gone pear-shaped.
