Yes, you do uninstall the app. But today's question is "how do you uninstall apps from Mac completely?" You can remove normal files like documents and movies by dragging them to the trash. But doing the same to the apps will leave lots of leftovers and junk files on your Mac. Here we're going to show you how to uninstall apps from Mac completely.

How to Uninstall Apps from Mac Completely and Manually?

To completely remove apps from Mac manually, you need to find all of the associated files that come along with the apps. So this means not just dragging the app icon to the Trash bin, but to search and find the depths of the system app files on your Mac and get them all out of your disk.

Let's see how to locate the locations for the most common files that are associated with apps. To remove the app leftovers, go to every folders and find files with the app name you can send them to the Trash.

So, when uninstalling any app, you have to go over each of these folders one by one and remove the followings:

1. Library can be found in ~/Library/

2. Plug-ins are located in ~/Library/Address Book Plug-Ins/

3. App preferences are located in ~/Library/Preferences/

      4. Binary and dock icons can be found in /Applications/

5. Application support files are located in ~/Library/Application

6. App saved states are located in ~/Library/Saved Application State/

7. Crashes are found in ~/Library/Application Support/CrashReporter/

8. Support Caches can be found in /Library/Caches/ and ~/Library/Caches


There are many more hidden files which you can't be accessed to. The system will prevent you from deleting some app files. Then these files will be left behind forever after you uninstall the app.

As you can see, it's not that easy to remove apps from Mac manually if you are not quite familiar with Mac OSX system. When you delete apps from Mac manually, be sure only to remove an app file or folder when you're sure of what it is. Removing the wrong files, let's say some system key files could cause problems with your system or even crash your system.
