Hi there, as usual, Mac has a built-in remover allowing you to uninstall any third-party applications from your device. You can open Finder > Applications > find the app you want to uninstall > drag it to trash. Followingly, delete its associated files scattered in different folders one by one. After these actions, you complete the app uninstallation.
If you're tired of finding every associated file in sorts of folders, you can use iBoysoft MagicMenu to complete this task. It gathers all associated files including user files, root files, packages, caches, preferences, etc. for you to determine what to delete. Once you check the files you want to delete along with the app uninstallation, iBoysoft MagicMenu will proceed with the rest of the work. It's quite convenient to use and worth a try!
