Perhaps Spotlight indexing is taking place? We can also run Activity Monitor and sort the list by “%cpu” to see which process is consuming excess time.@CaseySJ So I decided to do a brand new clean install of Catalina, but rather than just running an updated, I wanted to essentially start everything from scratch.
I followed the build guide step-by-step and got everything running beautifully. But just as before, I have one bizarre issue: my CPU is pretty much idle non-stop. It hovers around 85%–95% idle. Opening apps takes quite a while, various tasks take much longer than they should on a powerful machine like this. I pretty much never see any spike in CPU load in Activity Monitor. Any ideas as to why this may be?
