In Mac OS X the task of uninstalling a program is really simple and intuitive, but it has a downside, and it is that many times it leaves us files on our computer that are not worth anything and all they do is generate problems.
Therefore there are applications such as AppZapper, who are in charge of doing a complete uninstallation of the application, erasing all your files and settings so we don't have problems in the future.
The negative part of all this is that the program is paid, when there are other similar applications that for zero euros give us the same. But if you want the best, then pull AppZapper.
