Preview thumbnails not displaying in Finder (Monterey 12.7.4)

  • Safe mode doesn’t solve the issue either.
  • The search on Activity Monitor for "com.apple.quicklook.ThumbnailsAgent", force quit, and relaunching the Finder works momentarily.
  • Any new file I create after that, it goes back to the icon file but not the preview thumbnail. I work creating school material, so that preview is very useful to me.


Does anyone know of a permanent solution for this? It's pretty annoying having to do the activity monitor thing 10+ times a day, specially when the relaunching won't re-open the Finder windows I had to relaunch. Then, I have to open them again manually.


I have read the following in some forum, but I've not tried it yet, anyone knows if it will help as a permanent solution if none other is out there:

----------

Dock this script created in Automator and saved as an App and you can even set a short cut if you will:


Code:

do shell script "launchctl kickstart -k gui/501/com.apple.quicklook.ThumbnailsAgent" user name "YUOURUSERNAME" password "YOURADMINPASSWORD" with administrator privileges


do shell script "killall Finder"

------------


Any tip, help, and specially a solution will be appreciated.


Thanks.

Thank you. Sorry for missing that you had tried Safe Mode already.



One other thing you can try is to delete Finder preferences. Sometimes the plist file may become corrupted, and that can cause unexpected behavior.

In Finder, press Command-Shift-G and paste

~/Library/Preferences/com.apple.finder.plist


drag the file to the trash and relaunch Finder.



The script you mentioned seems to automate the process that you described of killing the quicklook agent and relaunching Finder, so at least until you can't avoid that, it will at least let you do that faster.
