Uninstall apps from my MacBook but it leaves unnecessary files behind, how to clear?

How can I uninstall the app and its files from my MacBook Pro? Deleting Apps this way even from the App Store leaves unnecessary files behind. I am wanting to delete them as well. That was why I was hoping to be able to uninstall them.

Uninstalling the apps from MacBook doesn't completely remove the files generated by the deleted app. To delete the leftover files of the uninstalled app, you can find and delete them in the Library folder under your user folder, or run a third-party cleaner for Mac to check the junk files on your Mac drive.

You may think that after you uninstall apps from Mac via Finder's Application folder, dragging-dropping to the Trash can, Launchpad, or third-party uninstaller for Mac such as iBoysoft MagicMenu, the configuration files, cache, logs, etc. created by the app could be removed automatically, while it is not like that.

Usually, such leftovers should take up little room, but the associated files of some apps may eat up a large share of your disk space, squeezing your limited storage. Then it is necessary to thoroughly remove these unnecessary files to release more drive space.

Method 1. Delete the app's leftover files with the Library folder

  1. Open Finder and click Go > Go to Folder from the drop-down menu.
  2. Enter ~/Library/ into the Go to the folder box and click Go.
  3. Remove the associated files of the deleted app in each folder within the Library folder, including Saved Application State, Cookies, Application Scripts, Containers, Application Support, Caches, Logs, and Preferences.

Method 2. Delete the app's leftover files with iBoysoft DiskGeeker

  1. Download, install, and open iBoysoft DiskGeeker on your Mac.
  2. On the left sidebar of the cleaner software, choose your startup partition.
  3. Click the Clean Junk button on the right toolbar.
  4. When it completes, check the box of the leftover folder of the deleted apps in UserCache, UserLog, Downloads, and UserAppCache, then click Clean to delete.
