Hi,
Sounds like this is very similar to the issue reported in Roon 1.7 causing MacbookPRO 2018 to run fans at high speed
To answer the questions you posted in that thread @noris
Mac Mini 2018 3.2GHz 6‑core 8th‑generation Intel Core i7
Mac OS Mojave 10.14.6
32Gb RAM 2666MHz DDR4
256GB SSD storage
It’s consistent for hours no matter what you do in the app.
Yes it does
Ubiquity -
185Mbps DL via Comcast DOCSIS 3 connected to
Unifi Security Gateway In turn to
Unifi 16 port managed switch
1Gbps connections on wired Ethernet to the core and library
Library is on a 6 disk Netgear ReadyNAS with dual bonded 1Gbps to the Unifi switch
Core is on a dell linux server connected on 1Gbps ethernet
Mac Mini is also connected on 1Gbps ethernet on the same switch
Google CCA is over Unifi AP on wifi
Also note that I have recently moved the core to its own Dell Linux box, the high CPU on the Mac happened both while it was the core and after the core was migrated and the mac is only a client. Once the core migrated to Linux, I removed the Roon dir in the Mac Mini Library and re-installed roon on the mac to clear any old lingering core things. The CPU going high issues was present (but intermittent) both before and after the re-install.
