I have the same issue I was checking out my pc and noticed hi memory usage
So I looked in task manager and found SMC.exe is using 2,369,216K Ram for hours
I rebooted and the same still using 2.3 gig of ram?
I have version 12.1.1101.401 I think its RU1 MP1?
This is just a test pc nothing much on it has very little use
New install only a couple months old
I checked 2 other work station’s one is using 4K the other 12K ram?
