You may not have the privileges to open the app, the app may be damaged, or it may not be installed. If you aren’t an administrator of your Mac, the administrator may be preventing you from using the app. Contact the administrator of your Mac. You may be trying to open an app that is not registered with Apple by an identified developer. Aug 01, 2011 If relaunching alone hasn’t fixed LaunchPad and apps are still not showing up, try deleting Launchpads database files located inside your home /Library directory, which forces them to rebuild. The directory path you are looking for is: /Library/Application Support/Dock/. Apr 05, 2019 All of your apps will be here, and you can launch any of them by clicking on the icon. The Launchpad has multiple pages, and you can swipe between them with three fingers if you’re using a device with a touchpad. Like iOS, you can pick up any of the apps by clicking and holding on the app and then moving it around. When you’re using your Mac, it’s possible you may encounter macOS’ “The application application.app is not open anymore” error – even when though this application is still open, and may even be clearly visible onscreen.
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.

Quick Tips
Here are the basic steps to fix Preview when macOS tells you it’s not open anymore, we’ve explained each step more fully in the article below:

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.

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.

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.

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.
