I just have to mention this great application. Many users ask if there is a app for deleting programs off the Mac, and usually, the answer is
AppZapper, which is a good application, but you need to purchase it.
A good free alternative that I have been using, is called
AppDelete, which is entirely free and very easy to use.
It works like the trash bin, and you just drag and drop anything you want to delete on Appdelete's bin, and it will find all relevant files for that application and delete them for you.
