This tutorial guides you on how to install OpenVPN on Mac using Tunnelblick, Viscosity, or the OpenVPN Connect Client.
As the OpenVPN project only offers a Mac client application for their business server (named OpenVPN Access Server), an alternative solution needs to be discovered to be able to connect to an OpenVPN server (Community Edition).
This article briefly explains what OpenVPN is, what are its advantages, what are the differences between the OpenVPN Access Server and the Community Edition server, what is an ovpn file, and how to set up an OpenVPN client on Mac.
How to connect to an OpenVPN server from Mac [Summary]
There are several ways to set up a VPN on Mac. However, if you need to use OpenVPN, depending on the type of VPN server you need to connect to (OpenVPN Access Server or OpenVPN Community Edition server), you have the following options:
- Connect to an OpenVPN Access Server:
- Connect to an OpenVPN Community Edition server:
- Option 1: Install and configure Tunnelblick (free).
What is OpenVPN and what are its advantages?
OpenVPN is a VPN protocol that is considered to be a standard and a model for future protocols.
As an open-source project, it was built to overcome the drawbacks of classical VPN protocols (PPTP, L2TP, IPSec) and to provide an easy to use VPN client to connect to OpenVPN servers.
The OpenVPN client can be set up on Windows, Linux, iOS, Android. However, on macOS, only a client application that is able to connect to an OpenVPN Access Server is provided.
OpenVPN has some important benefits:
- The OpenVPN project is open-source. Thus, it is free and constantly updated.
- OpenVPN is fast (especially on UDP).
- It is considered to be very secure. Its level of security is provided by the 256-bit encryption and high-end ciphers.
- It is stable and reliable.
- OpenVPN fully supports IPv6.

OpenVPN Access Server vs OpenVPN Community Edition
It is important to know the difference between the two types of servers that OpenVPN offers:
- OpenVPN Access Server is the commercial version of the OpenVPN server, it is designed for businesses, and it provides a user interface for administration.
- OpenVPN Community Edition (CE) server is the well-known open-source project that is used by many servers all over the World and by many companies to offer reliable VPN connections to their employees and users. Most of the VPN providers use OpenVPN on their servers as the primary connection protocol.
Since the purpose of this article is to explain how to connect an OpenVPN server from Mac, you may find more information on the differences between the Access Server and the Community Edition here.
Why use OpenVPN on Mac and what do you need?
There are several use-cases that require connecting your Mac to an OpenVPN server. Consider, for example, the following circumstances:
- You work from home and you need to connect to a VPN in order to access the company network and resources;
- You are using a VPN service that does not offer a custom-built, native VPN application;
- You are subscribed to a VPN service, but you prefer to connect using a light, open-source VPN client;
- You need to connect to various OpenVPN servers (exposed by your company, by several VPN providers, built by you, etc.) and you prefer to manage them from a single place.
All these scenarios require manually setting up the OpenVPN connections and the access to the .ovpn files that contain the connection settings.
What is an ovpn file?
An ovpn file (OpenVPN file) contains the settings necessary to initiate a connection for an OpenVPN session. It includes OpenVPN commands for the OpenVPN server and certificates or credentials for user authentication.
Here is a template of an ovpn file:
client remote myvpnserver.name auth RSA-SHA512 comp-lzo yes dev tun proto udp nobind auth-nocache script-security 2 persist-key persist-tun user nobody group nogroup <ca> -----BEGIN CERTIFICATE----- # insert content of your ca.crt -----END CERTIFICATE----- </ca> <cert> -----BEGIN CERTIFICATE----- # insert content of your user.crt -----END CERTIFICATE----- </cert> <key> -----BEGIN PRIVATE KEY----- # insert content of your user.key -----END PRIVATE KEY----- </key>
Most of the time you will receive the ovpn file from the VPN administrator or from the VPN provider. However, you may create the OpenVPN file yourself and type in the required commands. Of course, this is an advanced approach.
How to use OpenVPN on Mac
Connecting to an OpenVPN server depends on the type of server you want to connect to OpenVPN Access Server or OpenVPN CE server.
On macOS, you may use the OpenVPN Connect Client to connect to the Access Server, but you need to use a third-party VPN client to be able to create VPN connections to an OpenVPN CE server.

Tunnelblick runs on OS X 10.4 and higher, including the latest versions: High Sierra, Mojave, and Catalina.
Before you proceed with the installation make sure you have access to the .ovpn file(s). For example, if you have a NordVPN subscription load this page, click on Show available protocols, and download the OpenVPN config file corresponding to the desired location and protocol (UDP or TCP).

Connect using native VPN client apps
If you simply prefer the OpenVPN protocol (as it is more secure and reliable than the other VPN protocols) to hide your IP address and you don’t have a specific server to connect to, then you may pick a VPN provider that uses Open VPN.
In this case, you need to subscribe to the VPN service, download the custom-built VPN application, choose the OpenVPN protocol (UDP or TCP), select the desired location, and connect. It is the simplest way to use a VPN as you don’t have to perform any manual settings.
Most of the top VPN providers give access to the OpenVPN protocol these days. However, here are the ones that we recommend (as we test them regularly and we consider to offer excellent value): NordVPN, ExpressVPN, CyberGhost, ibVPN.
Accessing an OpenVPN server from Mac depends on the type of OpenVPN server you need to connect to. In the case of the OpenVPN Access Server, the OpenVPN Connect for Mac is available. For OpenVPN Community Edition, you need to use Tunnelblick or Viscosity as explained above.
Additionally, if you are simply interested in a OpenVPN connection you may install a VPN app provided by one of the above-mentioned services and connect with a click.
