Error with Deleting Apps

Sometimes it happens that while uninstalling some apps, you face an error with deleting their service files and folders. In this case, App Cleaner & Uninstaller shows the exclamation mark in the Removal window.

Here are the reasons why the files can’t be deleted:

  • There are running processes in the background related to the app. So check the running processes using Activity monitor, close processes related to the app you want to uninstall and try once again to remove the files.
  • The apps have kernel extensions that protect themselves from being removed. It is possible to remove kext files only in the recovery mode of your Mac. After kext files removal, you will be able to uninstall apps completely.
  • The files are protected from removal by System Integrity Protection (SIP) by Apple. Some apps can create files that Apple thinks are default system files and as a result, does not allow to remove them. To solve this issue, you have to disable the Apple System Integrity Protection.
