WOW!

Its not so much can't reach it is deciding what chain of devices to disconnect. Between the four TB3 PORTS on the Mac mini, four USB 3.1 gen 2 ports on the USB hub, and the USB ports on both monitors — are all in use and/or are very inconvenient to get to. Besides that my wife and I have shared an optical drive attached to a Mac mini server for years with no difficulty — until Catalina.

If we knew what it was we were doing, it wouldn't be called research, would it?
