Advanced NDI Troubleshooting on Mac

When Video Pencil display a warning triangle

This NDI connection problem seems to emerge when a Mac sends back a 169.254.* IP address over USB, which appears to be some kind of proxy/ad-hoc network port that NDI cannot use.
This is when the app shows a warning triangle, as it can see that there is an NDI server but it does not receive any video frames after connecting.
Figuring it out

Get a log with sudo killall -USR1 mDNSResponder and then look at the Console app, filtering on mDNS (
