To remove the apps on a Mac it is easy to follow the following steps:
Click on the open finder and access the applications folder.
Locate the application to be removed.
Delegate either to the Trash or by clicking the right-way and choosing Move to Trash.
In order to remove the app entirely, empty the Trash.
In the case of apps that are installed through App Store, you can also open Launchpad, where you need to press and hold the icon of the app, after which you need to press the X to remove the application.
