What Is Tunnelblick?
Tunnelblick is open-source software that can be used to connect to any VPN network that supports OpenVPN, including ExpressVPN. It currently only works on Apple’s OS X version 10.6 and higher.
Tunnelblick is the German word for ‘tunnel vision’, as VPNs are also called VPN tunnels.
What Does Tunnelblick Do?
Tunnelblick is an open-source VPN client. Unlike the ExpressVPN app, which is tailor-made for the ExpressVPN network, Tunnelblick works with all VPN networks that support the OpenVPN protocol.
However, you might find the user experience of Tunnelblick to be lacking in comparison to the ExpressVPN app for Mac OS X, especially when it comes to selecting locations and keeping your configuration files up to date.
How to Download Tunnelblick
You can download Tunnelblick from the official website. It is not recommended to download the software from any other sources, especially file sharing sites or third party sites, as they may be out of date, or worse, infected with malware.
You should always verify the integrity of your files by comparing the checksums with those listed on the Tunnelblick website.
