I didn’t do anything other than update the browser when a new version was available.
Maybe try a clean install (fresh user profile) and restart the computer?
Thanks. I had already gone through a restart of the Mac. It had no effect on the Task Manager issue.
Is there a reason to think that creating a new profile would affect the performance of Task Manager? I’d have thought that the parameters it looks at are global and wouldn’t be affected by anything related to a user profile.
