There are sorts of reasons why you can't delete applications from your Mac, and you can have a quick overview:
- 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.
Each reason listed above may lead to the trouble that you can't delete an app from your Mac, and you can troubleshoot it by reading this article: Delete Apps on Mac that won't Delete (Launchpad/Finder)
