Running into the same issue.
- Mac Mini (2018)
• Mojave 10.14.5
• Roon 1.6 (build 416)
Roon.app pegs the CPU whenever the app is launched. Sustains 400-500% CPU on a 6-core machine.
The behavior of the app doesn’t seem to affect the CPU usage. Doesn’t matter if it’s idle or playing music.
Roon is operating in client mode only, talking to Roon server (linux) attached to the same local switch. At idle, no noticeable network traffic between the client on the mac, or the roon server+bridge on the linux host.
Problem is 100% reproduceable. Launch the app, and automatically spikes the CPU.
I’ve tried uninstalling and reinstalling the mac roon client, and the behavior continues.
Additional info: this happens on my Mac Mini, but the same build on my Mac laptop does not run into this issue. Same version of Mojave (10.14.5) installed on both machines. Seems to be associated with this specific Mac client, and not the back-end. Also, very light CPU usage on the roon-server running on Linux.
What additional details can I offer to help identify this issue?
