How to Completely Uninstall Mac Applications

By Lois Green, Wednesday, August 15, 2018

Dragging an app to Trash or deleting the app from launchpad doesn't mean that you have removed the app completely from your MacBook. A complete uninstall involves removing not only an app itself but also its associated files. Deleting these application files is essential because:

  • You can free up more space in Mac hard drive;

  • You can get rid of corrupted application files that cause trouble.

So here we'll look into what these app files are, and how to access application files on Mac so that you can have the apps uninstalled completely. The tips can be used in both macOS Sierra or an earlier OS X, like El Capitan, Yosemite.

What Do App Files Include?

When an app is installed and runs on your MacBook Pro/Air, it usually needs to generate some supporting files. These app files often include: 

  • Caches;

  • Plugins;

  • Saved states;

  • Preferences;

  • Support files;

  • Crashes report;

  • Launch daemons;

  • Launch agents;

  • Startup items.

The vast majority of applications include first six types of app files while few applications need to use LaunchAgents, Preference Panes or Startup Items. 

How to Access App Files on MacBook?

Apps store their app files in the Library folder on MacBook hard drive. And since OS X Mountain Lion, Library folder is hidden on Mac. To access Library folder, you can hit Command + Shift + G to bring out "Go to the folder" window and type ~/Library. And the app files will be stored in these folder under Library folder: 

  • Caches: ~/Library/Caches/(App Name)

  • Plugins: ~/Library/Address Book Plug-Ins/(App Name)

  • Saved states: ~/Library/Saved Application State/(App Name)

  • Preferences: ~/Library/Preferences/(App Name)

  • Crashes report: ~/Library/Application Support/CrashReporter/(App Name)

  • Support files: ~/Library/Application/(App Name)

  • Launch daemons: ~/Library/LaunchDaemons/(App Name)

  • Launch agents: ~/Library/LaunchAgents/(App Name)

  • Startup items: ~/Library/StartupItems/(App Name)
