Roon Remote primarily on M1 Mac Air. Though I use iOS devices all current version and a couple of older Mac laptops depending where I am in the house. I have 8 zones and some gear doesn’t appear until powered on like my NAD M33.
Same here. 2011 headless macmini (i5 -16gb ram)running Roon server for quite some time with no issues. Ever since the latest update I start hearing the fan go crazy at odd hours and without any music playing. I Remote Desktop to the mini to check it out and it’s always Roon at +100% cpu. My system never displayed behaviour like this before. It’s software and things are bound to go wrong from time to time. I can live with that. But this is on a different level. Apart from the fact that it makes the software almost unusable, it is at some point going to fry the cpu!!!
Today, after Roon CPU (Mac Mini - M1) went over 100% again (doing nothing) instead of restarting the core, I restarted the remote player (an Intel iMac ) and amazingly, everything got better. The core CPU usuage dropped to the teens and the player was producing searches with fast results
I do believe I now have the issue mentioned in this post
If a remote restart helps, it sounds like you could be dealing with the issue mentioned here, though I haven’t seen reports of the issue causing high CPU usage:
After the fix is released for that issue, we can check to see if it has helped in your case as well.
