PS I just noticed it is making an error sound when I press Cmd-Q. I closed all other apps and there is no warning message or anything. All connections are closed and I only have the Profiles window open.The Quit Core Shell menu option is greyed out as shown in the attached screenshot.
Jonathan, are you able to reproduce it? And could please select "Report" button once macOS prompts you report a problem for a Force Quit action. And, send me the the text of report problem dialog directly should help me a lot.
It happens every evening when I have been using Core Shell all day. I was unable to reproduce the problem this morning.
I found this evening that, even with the Profiles window closed, the app will still not shut down. Force Quit did not produce the Apple diagnostic dialog.
I have been unable to find any logs for the app - if you advise where they live perhaps I could send you them?
One thing that is also different (as well as Big Sur) - this computer was new a couple of weeks ago...
Kind regards - keep safe. Jonathan
