I downloaded Fitbit onto my computer and then deleted all of it, but I can not get the icon to delete from my menu bar. I have tried to drag it over so it will delete, but it will not move.
If you have the Fitbit Connect installer software the Downloads folder on your computer, just run the Uninstall Fitbit Connect.app:
If you don't have the installer, download a new version here, then run the Uninstall app.
It is also a good idea to reboot after the uninstall process completes.
