How can I remove a VPN service when the remove button is disabled? I added a VPN config. Now I want to remove it, but the - button is gray and disabled.



I checked some answers from this Apple Support Communities thread:


  In Terminal: networksetup -listallnetworkservices
  In Terminal: networksetup -removenetworkservice networkservice
  In Terminal: networksetup -listallnetworkservices  


…but I cannot remove all.    

How can I fix this issue?
To remove the VPN Profile from your Mac:

System Preference > Profile > Vpn One Click > Remove.
