How do you delete Dropbox from OS X Yosemite? So this seems like an obvious one, but after some searching around the web and Dropbox's bad help section I've really come unstuck with this.

I'm trying to delete the official Dropbox app from my Macbook and everytime I try and move the .app package to the trash by right clicking it says that it can't because the app is being used elsewhere.

Is there anyway I can go about deleting it? I've checked Force Quit and it's not there, so I'm curious how you get rid of this thing.
Check Activity Monitor to see if there are any Dropbox processes running. If there are, kill them, then you should be able to delete the Dropbox app. If you have used Dropbox at all, then remember that any files you synched will still be on your MacBook's HD in /Users/[your_username]/Dropbox.
