This App Can’t Be Moved To Trash Because it’s Open On Mac (Sonoma)

Let’s See, Mac can’t delete the app because it’s open in Backgroud of Use.  Are you trying to remove unwanted Apps that are installed on your Mac, But Mac System shows or gives a message like “app can’t be moved to the trash because it’s open or in Use”, “After force quiet app running the app on screen still not deleting”.

Here I found the exact solution for all the Mac users who are running any macOS. I also discussed why this happens for the selected apps that cannot delete from Launchpad or under the application folder. Becuase it stays on Top Menu Bar like Google Drive, DropBox, Skitch…after quit from the screen.

Also, a message clearly shows the app is running, open, or in use. So, first, we need to find where the app is open and how to identify it. In the reply, the activity monitor will help to find running the app in the background, then force close from the activity monitor.

Our readers mail us and ask the solution for queries like they can’t empty trash Mac because don’t have permission, file in use or facing error 8003, or some guys getting error code 50, or their time machine, can’t empty trash on Mac external hard drive. We advise all of them to follow the given solutions.

Use Uninstaller

Can’t uninstall the app after force stop?

Still, can you uninstall the app after stopping all app processes? Now, you must use the uninstaller app for the app you installed on your Mac. Some apps keep the installer app in the Applications folder or You have to download it from the app’s official website. To find the app uninstaller on Mac,

Open finder > from the top menu Go > Applications > Utilities > Find the uninstaller for the app you are looking for. Here’s my screen,

  1. Thank You so much! I had downloaded and tried pCloud. It was no good, and they have NO uninstall instructions at all, not even in their FAQ’s. pCloud won’t let you move the application to the Trash, and says it’s open. Companies that pull this nonsense, and won’t let you uninstall their garbage should be punished by the DOJ.
    Thank You again for your help.
