Previously in macOS Big Sur pressing the space bar on an image/video file, Preview.app shows the preview of the media content (image content / play video), but now in macOS Monterey (version 12.0.1 (21A559)) it shows the thumbnail of the media file, its name, size and last modified timestamp. Why is that? Is this happening for everyone or I have something off in my system? I recently updated my macOS from Big Sur to Monterey.
Thanks for the answers, for me the thing that worked was to reset Preview and then restart the OS. By resetting the Preview app I mean to delete all plists and caches.
Also few suggested to restart Finder, when I do that my whole system hangs and I cannot do anything, not even shutdown/restart the OS, I have to resort to forcefully killing (shutdown) the system. Kindly let me know in case I'm doing something wrong.
