On a related note, I still find it odd that some macOS apps makes you drag a disk image to the Applications folder, and that's just one of at least three different ways to install apps on a Mac.
There’s a frustrating issue with macOS, where the app you’re using stops working and spits out an error message saying it isn’t open anymore. This mostly happens with Preview, but it can affect any app on your Mac, including Finder, Safari, the App Store, and others.
When this error occurs, the app you’re using becomes unresponsive and the following alert pops up:
Despite the error message, your app still appears as though it’s open. There may be a dot beneath it in the Dock or it may still have open windows. But you’re unable to use it. With Preview, that means you can’t open PDFs, screenshots, or other images anymore!
This article explains how to fix this error and get your apps working again. We’ve even gone so far as explaining how to fully reinstall macOS, in case this issue keeps cropping up again and again.

Step 1. Force Quit Preview
The first thing to try and do — although it doesn’t always work for this error — is to close the unresponsive app. Despite the error message telling you Preview “is not open anymore,” it usually is. But it has frozen and needs to be reopened.
There are two ways to Force Quit an app in macOS: using the Force Quit window or using Activity Monitor. If either of these methods works, make sure you reboot your Mac before opening Preview again.
How do I close Preview using the Force Quit window?
- Press the command+option+escape keys to open the Force Quit window.
- If the escape key on your Touch Bar is unresponsive, go to > Force Quit from the menu bar.
- Select Preview from the list of applications.
- Click Force Quit, then reboot your Mac.
How do I close Preview using Activity Monitor?
- Open the Activity Monitor application in one of these ways:
- Go to Finder > Applications > Utilities.
- Or go to Launchpad > Other.
- Select the CPU tab, then click ‘Process Name’ to sort the processes.
- Find and select Preview in the list of processes.
- Click the stop sign button in the top-left of Activity Monitor.
- Choose Force Quit, then reboot your Mac.
Step 2. Reboot your Mac
If it’s not possible to close Preview using Force Quit or Activity Monitor, you can close it by rebooting your Mac instead. This forces any apps that macOS says are not open to restart, bypassing the error message.
The safest way to reboot your Mac is using a soft reboot, but that may not be possible if the unresponsive app cannot close. If that’s the case, you have no choice but to use a hard reboot. We’ve explained both reboots below.
How do I soft reboot my Mac?
- From the menu bar, go to > Shut Down.
- Uncheck the box to reopen windows when logging back in.
- Confirm you want to Shut Down.
- Wait at least 30 seconds for your Mac to power off.
- Briefly press the power button to turn your Mac on again.
How do I hard reboot my Mac?
- Performing a hard reboot may result in lost data or corrupt files. If possible, save your documents and back up your Mac first.
- Press and hold the power button for 10 seconds or so until the screen goes black.
- Wait 30 seconds, then briefly press the power button again to restart your Mac
- In the alert window that appears, click Cancel to avoid reopening any apps.
Step 3. Remove your Preview preferences
If you still get the same error message — ‘The application “Preview.app” is not open anymore’ — you may need to remove some of your preference files.
These are small files that macOS automatically creates to store your settings for each application. You can usually remove them without losing any data or causing problems, but we recommend you back up your Mac first just in case.
Follow each of the suggestions below, testing Preview again after each one.
We advise you to move the preference files to a new folder on your Desktop for safekeeping, that way you can always put them back if something goes wrong. If this works and your issue is fixed, go ahead and delete those preference files.
How do I remove my Preview preferences?
- Open Finder, then from the menu bar select Go > Go to Folder.
- Type the following location and click Go:
~/Library/Preferences/com.apple.Preview.plist - Move the highlighted preferences file to your Desktop for safekeeping.
- Reboot your Mac and test Preview again.
- If the error persists, repeat the steps above for each of the following files:
- ~/Library/Containers/com.apple.Preview
- ~/Library/Containers/com.apple.quicklook.ui.helper
- ~/Library/Preferences/com.apple.Preview.LSSharedFileList.plist
- ~/Library/Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist
- ~/Library/Saved Application State/com.apple.Preview.savedState
Step 4. Update or reinstall macOS
Hopefully, that’s all you need to resolve the ‘“Preview.app” is not open anymore’ errors. But if you’re still experiencing problems, there might be a bug in your operating software. You can fix this by updating or reinstalling macOS.
We suggest you update your Mac to the latest version of macOS first. Apple frequently releases patch updates to fix bugs like this, but you can’t benefit from them if you don’t keep your machine up-to-date.
If you’re already running the latest version of macOS or if an update doesn’t solve anything, you need to reinstall macOS using Recovery Mode. This shouldn’t affect your data — although we recommend you back up your Mac first anyway.
Reinstalling macOS rewrites every line of code in the operating software on your Mac.
How do I update to the latest release of macOS?
- Connect your Mac to a working Internet connection.
- Go to System Preferences > Software Update to check for new updates.
- Download and install any updates your Mac finds.
How do I reinstall macOS?
- If you haven’t already, make a new backup using Time Machine.
- Use the following instructions to boot your Mac into Recovery Mode:
- Go to > Shut Down and confirm you want to Shut Down you Mac.
- Wait 30 seconds for your Mac to fully power off.
- Briefly press the power button, then immediately hold command+R.
- When the Recovery Mode screen appears, click Reinstall macOS.
- Follow the on-screen prompts to complete the macOS reinstallation.
