I'm trying to use renice to raise the priority of a running process in MacOS version 11.5.2 as follows:
sudo renice -20 PID
I get no error messages from bash, yet the Activity Monitor shows no change in the process.
Is there a problem in this area?

It is going to be very difficult to evaluate any change in process scheduling priority by looking at Activity Monitor. Most apps are UI-bound and just sit there idle waiting for events. What you see in Activity Monitor is a very coarse sampling of process utilization over time.
Open Terminal and enter the following command to learn more.
man renice
Mea culpa, it did work. The app is. now running much faster.
