I wrote some endpoint code in November-December, and it was running fine since Dec 29.
This week I decided to make one little tweak, and launchd stopped launching the service (with a status of -9) when my GUI app tried to connect to it.
After a lot of trial & error, I discovered I have to manually code sign the endpoint binary now. I am almost certain I wasn't manually code signing in December.
Is this a recent feature with a Catalina update sometime in this past month?
Thanks,
