I created an image file by pasting an image into Preview (Command + N). When I want to save it, the Save dialog does not appear. The Preview window looks as follows: The red button in the upper-left corner shows a dark dot - indicating that the file has not been saved. When I click on the red button, normally a Save dialog should appear - but nothing happens. I tried going into the menu bar to click "Save..." - nothing happens. I tried Command + S - nothing happens. Every time I shut down the computer, I need to force quit Preview (otherwise Preview stops the shutdown, since it has a file unsaved). However, every time I turn on the computer again and open Preview, the unsaved file is still there.
I am on a 2019 MacBook Pro running macOS Monterey Version 12.0.1. I also have a similar issue with the Save dialog not showing when I want to Save as PDF from the system print dialog. I also see what appears to be the same issue for TextEdit and Microsoft Office in the unsolved question here .
