Tunnelblick

If you wish to surf the web without any concerns regarding privacy, a Virtual Private Network service like OpenVPN is exactly what you need. If you decide to use OpenVPN, you may also want Tunnelblick, which provides a graphical user interface for the aforementioned software. Regardless if you intend to set up OpenVPN as a client or server, Tunnelblick will make everything easier.

The application is free and open source. It contains all the necessary binaries and drivers, including OpenVPN itself. In other words, extracting and running an executable is all you have to do, just like with any other Mac OS X application. This also means that you don't have to install any additional tools for this application, but it should be fairly obvious that you will need access to a VPN server.

Tunnelblick works with VPN configuration files, which you can get from network managers or VPN service providers. If you don't have such a file, the application can create a sample file, which you can edit according to your own preferences. Also, a few instructions are provided, so you won't encounter any difficulties when importing your configurations.

You can load one or more configuration files on the same interface and switch between them or make a few tweaks whenever you need. Tunnelblick provides a clean and efficient user interface, with easy to understand controls. You can access several sections, via navigation buttons, to find controls for connecting to a VPN, enable or disable certain notifications and more.
