  This tutorial will show you how to set up ExpressVPN on Mac using the Tunnelblick GUI (graphical user interface). Tunnelblick is a free, open-source GUI (graphical user interface) for OpenVPN on macOS and OS X.
  
  Not all ExpressVPN locations may be available for manually configured connections. To use the full list of VPN locations, use the app setup.
  
  Important: The OpenVPN manual configuration does not offer the same security and privacy benefits as the ExpressVPN app. If you are located in a country with a high level of internet censorship, you are recommended to use the ExpressVPN app for a more stable VPN connection.
