How To Fix Quick Look Preview Finder issue on macOS Monterey

On macOS, especially after upgrading to Monterey, Preview sometimes stops showing full window previews for images, PDFs and videos. Instead, it shows this tiny preview window. This is the only fix that worked for me. Let me know if this helped you.

this is not a fix, this is a hack, and it only 'fixes' it for 20 minutes.

How refreshing--a tutorial that is short, to-the-point, and actually solves the issue. Thank you!

[@zvrrow]

Incredible! Quick, and to the point. Problem solved. Thank you so much!

[@MrDIYca]

Glad it helped!

[@richardbolivar]

This is a temporary solution

[@OscarBuelna]

I usually don't comment on tutorials but damn I really wish all tutorials were like this! Straight to the point and worked. Took longer to write this comment than to fix.

Man! You are the best ! It worked as per your instruction and one time restarting system !

[@rachel987-q6c]

I see a few QuickLookUIService options but none of them say PID like your video. they either say "finder" or "firefox" or "preview" or "adobe illustrator". should i force quit all of them?

[@TourayMediaGroup]

Thank you for this quick and effective video. It WORKED!

[@reecemcdaniel8207]

Bro, thank you SO MUCH! I was getting so frustrated. Love the short video, so helpful

[@rachel987-q6c]

i did a force quit on the adobe illustrator one and i still cant see a preview of my EPS file when I click space bar.

you can also go to the apple menu top bar > force quit > finder, but it will bug again later, isnt there any way to permanently fix this?

not that I know of. I usually find myself doing this trick every 2-3 months
