Apple has configured Macs with a built-in app remover, which is capable of deleting unwanted apps from it except the ones coming with macOS. You just open Finder and go to the Applications folder, then find the app you want to delete, followingly, drag it to the Mac Trash lying on the Mac Dock. Yet moving to trash doesn't mean you have completed the app uninstall, seeing there are lots of leftover files of the app staying on your computer. You have to find every single file and folder scattered on different folders and uninstall them as well.
This task is quite complex. We recommend you utilize a professional app remover -- iBoysoft MagicMenu, which collects all associated files or folders of the app being deleted, and you can check what to delete along with the app. It saves lots of time and effort in dealing with the app uninstall!
