AppZapper is an application for Apple's macOS developed by Austin Sarner and Brian Ball. The software is an uninstall utility which extends the method of uninstalling in macOS, which is dragging the application one wants to uninstall to the trash. By dragging and dropping an application to uninstall in AppZapper, the application searches for additional files residing in directories other than that of the original application, such as preference files and package receipts, the user is then able to select unwanted files and delete them.
