These steps are common for deleting most preference panes on a Mac But there is something you should keep in mind. Some plugins may leave their service files on your disk, so you should search for them manually and get rid of all the files related to certain preference panes. You can quickly find and remove them using a free application called Funter, which finds any files on a Mac, including hidden service files.

Just type the word “Perian” in the search field of Funter, and in a moment the app will display all the support files of the plugin. Note an example in the screenshot.

Here you can see that the file Perian.PrefPane is in the Trash, while its support file, org.perian.Perian.plist, is still in the Preferences folder. You can delete this file using Funter, or click the magnifier icon and open it in the Finder to overview the files and then delete it.

As you can understand, deleting plugins just from Preference Panes may not guarantee that you have uninstalled them completely. That’s why we recommend using the professional tool, App Cleaner & Uninstaller, designed to delete applications and extensions on a Mac completely and safely.

The advantage of App Cleaner & Uninstaller is that it finds and removes all the support files of applications and does not leave remains on your Mac.
