Thank you, that is the right solution to restore Quick Look.

Reiterating what @TheTrappistMonk found in Dropbox, now for OneDrive: When I first open a synced folder and try to preview a pdf file with Quick Look, it shows only a thumbnail of the first page. But if I open the same file in Preview, then close it, and again try Quick Look, it now shows the usual sneak peek of the whole file, with all its pages.

My guess is that the file was actually being indexed on cloud storage, but after opening it there's a cached local version, and it's that cache that Quick Look is actually consulting to build its display. But that's pure guesswork, not informed by any knowledge of the underlying code.

I have tried all these solutions but nothing works. More oddly, Quick Look does not appear in the Extensions pane of System Preferences. Has Monterey not installed properly? Help, I use Quick Look a lot and not having it is very annoying.

Nothing works for me.

There is no option of Quick Look in Extensions, the above keystroke combination does nothing etc. I have tried all the fixes suggested on this and other forums, and nothing helps.

What I have realised, though, is that files stored on my laptop itself can be previewed with Quick Look, but but I keep my main work in Dropbox as it needs to be accessed by my home laptop and office iMac. The ones in Dropbox (ie stored in the cloud/with a third party etc) do not preview correctly and only show a thumbnail preview.

Apple: can you please look into this? It is a major shortcoming/bug in this system update and needs to be fixed PDQ.

Select > Command > Option | not working for me

or relaunching Finder | did not fix it for me

or Preferences -> Extension | there is no extension called Quick Look or something else

and it is not only Quick Look while pressing space bar. its all the icons of some files in folder on desktop or on server. main files without any preview are mp4 and EPS. Sometimes PDF, PSD, and AI as well.

Agree with TheTrappistMonk … please fix it very soon. working is more complicated now. and after some weeks it's really annoying …

all the recommendations in this thread or these on other websites are not working.

Thanks but it only shows Rotate left, Markup, Create PDF, Trim, Convert Image. However after a reboot, I do get large images again using the space bar in Finder. I seem to have to reboot ofter or disable/enable bluetooth as my Magic Mouse often stops scrolling as well since Monterey upgrade.

Relaunch does work, but it doesn't seem to do anything to my eps files. QL works fine on all of my other files (ai, psd, pdf, jpg, etc.) , but not eps. I have also reported the bug to apple through the site, so I'll just add mine to everyone else's at this point.

I wonder if it's related to the memory leaks we're hearing regarding macOS Monterey?

No. Some of the memory leaks are known to be caused by setting the cursor to a color other than the default black.

This works for me. Monterey somehow made storage in the cloud (for OneDrive in my case), the default whereas I had previously had locally as well. Ensuring files are local seems to make QuickLook work fine and not be simply an icon.

Hmm … can not find quick lock at the location you told. Restart doesn't help. it is just not there. Only Core Sync Helper is available - nothing else.

So Quick Look is out of order for EPS, PDF etc. as well. Even the preview of EPS, PDF etc. in a standard folder doesn't work … feels like a windows computer now painful ^^ hopefully apple will fix this (for me huge) problem with 12.2 very very fast. i really need the preview of EPS files :/

in one folder i have more than 300 EPS files. all now with the same icon - no previews. yay -.-

i had tested several ways. as well clearing quick look cache at library, settings, press option-space … it is crazy but nothing works for EPS and PDF here. Files on Server and Files on Desktop - all the same. Only for JPGs and PSDs it is working but not for any PDF or EPS. Icons of files, preview in folder and quick look via space or option-space … have no clue anymore what to do. hopefully my new mac arriving in april will do it. my bad i updated way to early at 12.1 … normally i wait until .3 or .4

A quick update as I go along noticing how Quick Look is working or otherwise:

If I open a file in my Dropbox folder and then close it again, Quick Look seems to work the next time I try it.

But that's no good for files that haven't been opened yet.

Apple: how is it going with your attempts to fix this one?
