It turns out that Apple is incrementally deprecating extensions Norton (and others) used to enable Vulnerability Protection. (If I leave it switched off, Airplay works.) I do not know what Vulnerability Protection Exceptions to set to completely remedy my problem. Then I have to switch it off to reconnect to my playback devices, and can switch it back on as soon as I have reconnected. I switch it back on and playback works (except Airplay) until I restart Roon. I switch off Vulnerability Protection when I want to connect to a playback device. It is part of the Norton 360 Firewall and can be switched off separately from firewall connection blocking. I have discovered the cause of my problem is Vulnerability Protection. Thank you very much for your help, Andrew, and wish me luck with my Roon issues! I’m going to attempt to describe this crazy issue in the support column.

I am seeing a few other posts in the support area that have symptoms that might be similar (but not identical) to mine. This sounds like a network problem, doesn’t it? So I took a Bluesound Pulse Flex 2i speaker and my Mac mini over to the Wi-Fi router (TP-Link) and plugged them both into Ethernet ports on the back of the router. Then would become unstable again as described above. The Roon Ready speakers remained unstable through cycling disable/enable and would stabilize only after uninstalling Roon. As soon as I would try to stream an album from Qobuz or Tidal the Roon Ready speakers become highly unstable and finally disappeared altogether.

My Airplay Oppo Sonica speaker played the radio stream with dropouts. Each Roon Ready speaker (Bluesound Pulse Flex 2i) would play for a few seconds if I streamed a radio station such as Radio Paradise. What happened? I was able to enable my Roon Ready sources whereas I could not do so before reinstalling. Find and trash or delete immediately the Roon and RAATServer folders.Hold down the Option key (or Alt)(⌥) to unhide the Library folder.Open Finder and click Go in the top bar.I know that you do not need to know this, but in case someone is following this thread, I am posting it for similarly novice level users such as I. I learned that to get to the library I had to follow these steps. I was able to follow your advice and was successful in fully removing and reinstalling Roon.
