Delete unwanted apps completely My child accidentally downloaded an inappropriate software and I want to delete all history of me ever having it. How can I do this?
It is a bit tricky under OS X/macOS. If you are not tech savvy, try a third party app.

Otherwise, open the Terminal (search for it via Spotlight), and then paste following line:

sudo find / -iname "NAME_OF_YOUR_APP" &gt;&gt; ~/Desktop/t.txt


Replace NAME_OF_YOUR_APP with the name your actual app you want to delete. Afterwards, you'll see a text file at your Desktop. Open it. Here you have all paths of the app you try to delete. Go via the Finder to every place and delete the files by hand.


  Be careful and make sure the files are really the once from the app
  and not duplicates from other apps in your system.
