There are two ways to uninstall programs from your Mac: drag-and-drop the app over the Trash icon from your dock or use a third-party utility to remove the tool. Whenever you try the first or the second option, there's a chance some of the application's files might still be left behind. One utility that helps you prevent this event from happening is AppCleaner, a tool that uninstalls programs along with all of their associated files.
This program helps you uninstall apps, widgets, and plugins from your Mac within moments. You just need to select the tool you wish to remove from your computer, and AppCleaner will display a list with all of its associated files. You can choose which files to keep or delete permanently from your Mac.
AppCleaner also features a built-in search tool that comes in handy if you're dealing with a large collection of Mac apps.
Another good thing is that you have access to the SmartDelete option. Every time you will attempt to send a tool to Trash, AppCleaner will offer you to uninstall it and delete all associated files.
The one disadvantage is the fact that it doesn't provide you with an option to search and delete leftover files from your Mac (data left behind after uninstalling a program from your computer before working with AppCleaner).
However, AppCleaner proves to be a reliable solution when it comes to completely removing programs from Macs. In addition, it's free of charge.
