I keep getting a popup message “The application “Preview” is not open anymore”.
Can’t open any of my screenshots, nor pdf(s) in Documents / Finder – not yet tried to open Pages / Numbers docs.
When I click on Preview icon on bottom toolbar thing happens.
It has a black dot below it.
Please help! I’m in midst of planning my father’s funeral, so really need to access lots of stuff!

Try force quitting preview by pressing the keys (all of them) Command+Option+Escape and choose t the Preview app to force quit.
If that doesn’t work, open the Activity Monitor (in Applications > Utilities folder) and quit Preview from there.
Once you are able to quit Preview, restart your Mac and try again
YOU MUST REBOOT for this to work

I’m having this exact message, trying to look at old photos.
All was well until I opened one that was just a number, with app ‘terminal’, which I then closed.
I’m worried I’ve messed up in something.

Same here. What to do about it?

Sorry to hear about your issue.
It seems you are not too familiar with settings and advanced features within your mac os.
Therefore I recommend you use a utility program that can scan and find errors and fix them automatically.
I use an anti-malware and anti-virus software for the past 2 years and it works very well.
Try them out by downloading and installing free (for a trial period)

I have the same problem, but Force Quit (Command+Option+Escape) doesn’t work and when I open the Activity Monitor under Utilities in Applications, there isn’t any Preview listed at all. There is a “Preview.app” listed under the Application section itself, but if clicked on, then the “The application “Preview.app” is not open anymore.” message comes up. Without shutting down the Preview app, I can’t shut down and/or restart my MacBook Pro. What to do?

having the same issue. forced to hard restart in order to get preview to work again. it would be great if Apple would figure this bug out and fix it. so far it seems the only suggestion is to reboot, which is really just a short term workaround and doesn’t really solve the chronic problem.
its very disruptive to completely stop everything i’m doing and hard reboot, start all my work and process all over again.

Let’s try this method:
1. Quit Preview (if you see it’s open in the Dock)
2. Open the Finder app
3. Choose the Go Menu
4. Select Go to Folder
5. Type in this location: ~/Library/Preferences/com.apple.Preview.plist
6. Move this file either to your Desktop or to the Trash to isolate it
7. Restart your computer
8. Try opening Preview again
Once you confirm that Preview works again, you can delete that old Preview.plist file.
Let us know if this works or doesn’t for you!

OK, preview now working but what do I do NOW with the Preview.plist file which is on my desktop?

first apple computer-(and last)-tried opening utilities, activity monitor, then it says quit preview?!? The list will not stop re organizing, bouncing, moving long enough to find any particular process, let alone click on it. Prefer not to reboot computer as I don’t trust it to restart without me losing something important. Many other issues, but this is my current predicament.

Having a similar issue with Preview failing to open.
Grateful for these tips.
Found& isolated com.apple.Preview.plist…. BUT my MacBook Pro is also refusing to Restart…
This problem started yesterday after I downloaded a Software Update.
The computer said it was going to “Restart” to finish Installing, but it never did…
And now when I select “Restart” and confirm “Restart” in the pop-up dialogue box… Nothing Happens.
I’m a Mac devotee & have never experienced these sorts of glitches in all my years of using Macs. Need a solution, please!

Try holding down the Shift key and press the button to turn your computer on (assuming it’s off)–this invokes Safe Mode.
According to Apple, Safe mode does the following:
Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:
Verifies your startup disk and attempts to repair directory issues, if needed
Loads only required kernel extensions
Prevents startup items and login items from opening automatically
Disables user-installed fonts
Deletes font caches, kernel cache, and other system cache files

Thank you, but my Mac Book isn’t off. It’s on. When I select “Restart” or even “Shut Down,” nothing happens. So I can’t use strategy suggested above to fix problem with Preview App, since I can’t “Restart.” Stymied. Thanks!

Close all your applications, if possible and then unplug it or press the power button to shut it down

Hi, Please help! I use Preview all the time but now it’s crashing every time I try to Adjust Color with this message and more: I tried the suggestions of Elizabeth but got stuck when you said to go to the Go Menu to add ~/Library/Preferences/com.apple.Preview.plist
please advise, thank you!!

This is very poor behaviour by an Apple app. I work in a professional setting and to blithely suggest restarting my Mac when this happens might be a solution but it’s a pain in the bum, given the interruption to my workflow. Surely Apple can identify and resolve this issue. It seems symptomatic of the degradation in quality of Apple apps we’ve seen increasingly over recent years.

I know nothing about computers – hit and miss. Peview wouldnt open. All suggestions too hard to do for this senior so had a “play”.
All fixed (by accident). Seems there was a document “jamming” the app. Once I got rid of it (sent it to myself) everything was sorted. No idea the technical aspects of all of this but saved myself all kinds of angst by just sitting there following a few “paths”
