Description Of Issue
I just got a new macbook pro 16, and installed Roon after installing all the software updates. Unfortunately, Roon on this laptop cannot find my external devices on the wifi-network. My older laptops still work just fine with it.
I would really like to make this my main Roon device. How can I fix the problem where it can’t find the external devices?
I’m jumping in with a guess, mostly because I can see that you’ve been waiting seven hours for some help. I’m wondering whether the issues you’ve encountered are caused by permissions settings in Catalina. The latest macOS is much more stringent and picky in this respect than its predecessors were and you might check the security and privacy settings. Hope this might be useful and good luck!
try turning off your firewall temporarily. If the devices are then seen, you need to add exceptions for roonServer, Roon, and/or RAAT to your firewall.
Update: I solved this issue today. It turns out that my old ISP still had hardware in my system, and the tech from the new ISP missed it. This was somehow enabling my new Macbook Pro to connect to the old system, even when every other device in my house connected to the new system. Some weird mac anomaly.
My new ISP sent out another tech today, and they solved the problem by removing the remaining gear from the old ISP.
