To configure your VPN to use on your MAC computer you will need to download the TunnelBlick file
You can download this zip file here
Once downloaded open the ZIP file and inside you will see a file called HW-MAX-VPN.tblk
Double click that file and it will import the configuration into TunnelBlick.
You can then use TunnelBlick (up on the menu bar by the battery percentage) to connect to the VPN.
You will then be asked for your username and password that were given to you in the email.
