How to completely delete Minecraft from my Mac?

My Macbook Pro is fairly old; 2005. So When I open Minecraft, it goes fullscreen and I can't get it to minimize (or do anything for that matter) unless I shut down the computer. Is there a way to stop this, or completely delete Minecraft?

Get a computer that isn't 9 years old

Open Finder and then click Applications and locate Minecraft in the list. Right click it and then choose "move to trash"
