Description Of Issue

As soon as Roon client on Macbook (15-inch, 2018 MacOS 10.15.7 (19H2)) starts CPU is pegged by Roon and RAATServer and remains at that level.

RoonAppliance and RoonServer.exe on core are using no CPU

covenant

This behaviour only began after updating both core and client to 1.7. Have restarted all devices with no change.

Ugly known issue for Mac users:

It is not an issue that affects only the Mac mini, many models affected, catalina, mojave…

FWIW I switched to wifi from ethernet and that has stopped it.

I would prefer to use ethernet but if it means listening to screaming fans and wondering what the melting temperature of my Macbook is wifi will do for now.

Hi @jimmy.kl,

We are still actively looking into this issue. You can try to toggle your WiFi on/off if this behavior re-occurs, as that has helped some users.
