I’m using a very similar Mac as yours (from Mid-2014) and roon is using around 15% CPU constantly while playing. Energy impact (whatever that means) is around 75. (Avg around 12)
I can run this for hours… (btw. the fan is not running)
i have noticed high cpu usage on 2017 mackbook pro also and it was already with previous 1.3 release so not limited to new 1.4 release. I am using my mac as controller only - not the player.
For me Roon takes consistently at least 8% of the cpu even if it’s only used as a controller and even if it’s in the background or on a different desktop. Most apps just go to ~0% when they’re idling. I suppose Roon never idles or it idles really hard.
“idles or it idles really hard” no idea but that made me laugh. I haven’t looked at battery drain on my laptop (windows) but will add to this thread if I notice anything I consider high for a controller + core.
