The High CPU usage issue is not isolated to Roon Server, RAAT and Bridge affected as well.
The issue started at 18.22 MST while nothing was playing the Mac running bridge was siting there idle.

Noticed in my UPS the load was about 150W instead of the normal 35W (idle PC), thought a malware was mining or so as I was not expecting that from Bridge.

Thanks Team.

What ideal Mac is this? Does it have the T2 chip? Does turning of WiFi help?

3

wifi has never been enabled on this iMac 2019 (no T2 chip)…

4

Any macs after 2018 are T2 chip equipped

Description Of Issue
Latest Roon Bridge updated last night and seemed to be running fine yesterday. Today, it runs using ~350% CPU (Roon Bridge) and ~80% CPU (RAAT Server). Quitting and restarting Roon Bridge does not affect CPU usage.

I think this falls under the umbrella of this issue/update from @support High CPU Usage on Mac Mini 2018 correct me if wrong.

FYI @Robert_Cruz users reported that if they do disable/enable wifi the usage will go down to normal levels.

Oh! Didn’t notice that issue/update, thank you for sending the link. Also, I appreciate you sharing advice on toggling wifi back on; it’s easy to do and I’ll give that a try. :slightly_smiling_face:
