Download and install TunnelBlick
The Tunnelblick application contains the Tunnelblick GUI, OpenVPN, and OpenSSL, so no other installations are needed.

If you are reinstalling, upgrading, or downgrading Tunnelblick, the window will show the version number of the current copy and of the new copy. The current copy of Tunnelblick will be put in the Trash before it is replaced.
The name and password of a computer administrator is needed to install Tunnelblick. Tunnelblick's imbedded OpenVPN needs root privileges because it needs to modify network settings by configuring new network devices, changing routes, and adding and removing nameservers. Because we don't want you to enter your administrator account name and password every time you start a VPN connection, Tunnelblick comes with a setuid root binary that allows it to start a VPN connection with super user rights. Tunnelblick uses your administrator account name and password so it can create this setuid root binary. Tunnelblick also secures itself from being modified.
Click the "Install
" button to copy Tunnelblick to your hard drive at the indicated location.
Once that is done (it may take a couple of seconds), a new window will appear, similar to the following:
