I want to get rid of Dropbox entirely from my Mac. I'm not a very advanced Mac user, and ordinarily apps can be uninstalled with ease, but not with Dropbox. I followed all the procedures according to this link https://www.dropbox.com/en/help/41 but when I try to drag the Dropbox icon from the list of apps in Finder, a message comes up stating "The item 'Dropbox' cannot be moved to the Trash because some of its plugins are in use." I have no idea what this means - everything else was deleted successfully except this and the icon in Launchpad. Any assistance would be greatly provided.
