For all of you MacOS and OS X users out there that are already sick and tired of using third-rate OpenVPN clients, the wait is over.

Enter Tunnelblick. This technological gizmo is an open-source and free client for OpenVPN that allows you connect to any VPN service on the market from a Mac OS or an OS X.

The default OpenVPN configuration files take the form of a graphical user interface for people all around the world. In fact, Tunnelblick is the Windows-only OpenVPN GUI for Mac users.


  • Open Source
  • IPv4 and IPv6 leak protection
  • WebRTC leak protection
  • Uses the latest version of OpenVPN
  • In-built kill-switch
  • Can function based on any OpenVPN configuration file


  • Harder to use than other custom VPN clients
  • Let’s have a look at what it can do and whether it’ll prove to be what you’re looking for after all.


In terms of speed, your performance is entirely dependent on your actual VPN provider. Since Tunnelblick is nothing else than a tool through which you can connect to a good-quality OpenVPN-based online security provider, it doesn’t have servers of its own.

At least not ones tailored to provide you with the same features that a full-fledged VPN would.

In the strictest sense of the word, Tunnelblick is a free software that will help you with properly setting up your OpenVPN configuration files on Mac OS and OS X Machines.



Again, for information on locations, the number of servers and overall coverage, contact your actual VPN provider. It really depends on whom exactly you have subscribed to. NordVPN, for example, has more than 4500 servers in as many as 60+ countries.

There will be differences between the multitude of online security providers on the market, both in quantity, magnitude, as well as the quality of said servers.



In the security and privacy-protection department, Tunnelblick provides you with the following features:

  • The latest beta version-only Kill-switch, one based on a firewall-type protection
  • WebRTC leak protection
  • Full DNS protection, both IPv4 and IPv6 leaks are fully accounted for and prevented. Actually, Tunnelblick doesn’t support IPv6 routing in the first place, and this means that it’s basically impossible for leaks to appear

Of course, disabling IPv6 is optional, and you can opt out to use it regardless

In order to enable the DNS leak protection, go to Configurations – Settings, and make sure that the boxes next to the Route all IPv4 traffic through the VPN and Disable IPv6 are ticked.

As for the kill-switch, only the latest beta version of Tunneblick possesses one. It will make sure your traffic and IP address will not be exposed in the case of a VPN blackout.

To enable it, go to Configurations, and click on the specific VPN configuration that you’re using. Keep in mind that this is the go-to procedure for activating the kill-switch. You have to manually enable it for each individual configuration.

Click on the On unexpected disconnect field, and select the Disable Network Access option from the drop-down menu.

Its efficiency and promptness were tested before by specialists by initiating a simulated blackout to see if the network access would be cut off. Ideally, no internet connection should have been available at that point in time.

The results were as expected – only by reconnecting to the VPN again would the internet connection be put back together.


Ease of Use

As I said before, Tunnelblick does have some extra steps in the installation process, and you have to work your way around the settings in order to properly set it up. It’s a bit harder to configure than another custom OpenVPN software.

Here’s the step-by-step guide that will take your hand and lead you through the conundrums of Tunnelblick:

  • Download the regular OpenVPN configuration files from your preferred online security provider. Keep in mind that for each server location, you will need a different configuration file
  • Download, install, and launch Tunnelblick. Enter your credentials, and then, on the Welcome Screen, select I have the configuration files option
  • Take the OpenVPN configuration files and drag them to the Tunnelblick icon in the menu bar
  • Click on Install, and then choose whether you want to use the client for yourself or for all users of your Mac. Most likely, you’ll have to re-enter your credentials
  • In order to connect to a certain server, just hit the Tunnelblick icon in the menu bar, and select a VPN server. When the connection completes, the icon will be colored in a darker tint, and if you hover over it, it will display additional information

Customer Support

Being a free software developed by the community, you would certainly not expect the customer support to be anything worthy of notice but, surprisingly, there are plenty of articles and FAQ documentation available on the website.

They deal with all sorts of problems and issues you might encounter while using Tunnelblick. In this sense, you can go to the Common Problems section if you want a more detailed approach.

If nothing else works and you still haven’t figured out what the problem is, you can go to the discussion forums where all the Tunnelblick developers will keep a tight schedule on answering user requests and questions.



As I said before, Tunneblick itself is free of charge, and it acts just like OpenVPN GUI in this sense. However, in order to use it, you have to connect to a VPN server. Granted, you can create your own private OpenVPN server but even this means you will have to pay a commercial VPN service.

At the end, why Tunneblick VPN out of all others?

There are plenty of other custom Mac VPN apps out there that will provide you with almost the same features. Why would you choose Tunnelblick?

Firstly, the software is available to the public. It can be peer-reviewed and analyzed by anyone. In other words, it’s an open-source client. As such, you can be pretty sure that it won’t put you in any immediate danger.

Secondly, Tunneblick appears to be extremely prompt when it comes to OpenVPN updates. Whenever one appears, they will implement it as fast as possible. So, the client is always kept up to date. This includes the security patches as well, of course.

It means that, when compared to other custom OpenVPN clients that will tend to lag behind in this area, Tunnelblick is exponentially more secure and more reliable. Moreover, the stability of the system itself is something that other clients can’t even compare to.

The MacOS platform is notorious for not having well-rounded support and compatibility from custom OpenVPN clients, at least not on the level that Windows has.

Tunnelblick is the single most popular app that the majority of VPNs on the market rely on to provide Mac support.

In the end, I would wholeheartedly recommend it to new and veteran users alike because it’s a very reliable and proficient client that will not disappoint.
