I speculate that you failed to remove an app from your Mac due to these factors, and you can check if I am right:
- The app you're trying to delete is in use.
- The application is pre-installed on your Mac and protected by the system.
- There's a temporary glitch on your Mac.
- The software is corrupted.
- The apps that won't be deleted from Launchpad are not downloaded from the App Store.
- The app is part of another program and needs to be deleted from within the main program.
- If the file you want to remove is categorized as Other and has a generic icon, it's likely a leftover of a deleted app.
You can stop the use of unwanted apps to delete the apps on Mac that won't delete, use a professional app uninstaller, disable SIP to delete system apps on Mac, kill processes related to the app in Activity Monitor, or more to complete the app uninstallation.
If you want to uninstall third-party applications from your Mac, iBoysoft MagicMenu is a fabulous app remover that not only removes the app from your Mac quickly but also lists all associated files like caches, preference files, user settings/files, downloads, packages, root files, etc. for you to determine what to delete. You can check the useless files by toggling the box close to them, and then iBoysoft MagicMenu will delete the app and files altogether!
