AppZapper is a nice little app that let's you remove any program from your mac and all files associated with it.
It cost's $12.95, but you can get a free trial that lets you remove 5 programs or anything else from your Mac before you have to pay.
The nice thing about this program, if you have it on your dock(very usefull) is that all you have to do is drag the app on top of the AppZapper icon, wether the program is launched or not, and it shows you what it will delete, then all you have to do is press the "Zap" button, and it's gone.
This program is available
here.
