How System Folders Become Insecure System folders are secure when macOS is installed, and usually only become insecure as the result of a program installer behaving improperly. Tunnelblick is for Apple’s OSX operating system only, and is free and open-source. It is the one we recommend for OSX, the only real alternative being the not-free-nor-open Viscosity client. The “best solution to connect via VPN” is likely the client that your particular VPN provider recommends as their servers and settings will be tuned for.

VPNs are primarily used two ways, or sometimes both ways simultaneously: – To securely connect a computer to the Internet, even though it may be connecting through an untrusted network a wireless network at a hotel or airport, for example ; and – To securely connect a computer to a company’s internal network or some part of it a branch office, for example.

Please see Privacy and Security for important information before you use Tunnelblick to attempt to make yourself anonymous on the Internet. In addition to Tunnelblick, you need access to a VPN server. Your company may provide one, or you can obtain VPN service from any of several VPN service providers, or you can use another one of your computers or a router to act as a VPN server.

It comes as a ready-to-use application with all necessary binaries and drivers including OpenVPN and Tun and Tap system extensions included. No additional installation is necessary — just add your configuration and encryption information. Tunnelblick is free software made available under the GNU General Public License, version 2 and may be distributed only in accordance with the terms of that license. The Tunnelblick disk image includes a link to the Tunnelblick Documentation.

There is also help available in Tunnelblick’s windows by clicking on the question-mark “? An older version of Tunnelblick works on OS X That version is a Universal bit application, so it runs as an application in bit mode on both Intel and PowerPC Macs under bit and bit kernels. You need a VPN server to connect to. It could be a server at your company or at a VPN service provider, or it could be a VPN that you have set up yourself at home. Tunnelblick indicates that the VPN is connected by showing the “open” tunnel in your menu bar usually near the Spotlight icon.

An easy way to check if web traffic is going through the VPN is to put enable “Check if the apparent public IP address changed after connecting” for the configuration. Be sure to select all configurations that you want to change before making a change.

Binaries for all available modern versions of Tunnelblick are available on the Downloads page. Binaries for all available older versions of Tunnelblick are available on the Deprecated Downloads page. You can build Tunnelblick from the source code on Tunnelblick’s GitHub site. See Source. A “deployed” version of Tunnelblick is a customized version of the program, which includes everything you need to connect to a VPN: the program itself, configuration file s , and key and certificate files for encryption.

If you download Tunnelblick from this website , it is not a deployed version. You must also have configuration, key, and certificate files, which should be provided to you by your company or your VPN service provider. See Deploying Tunnelblick for detailed information about deployed versions of Tunnelblick. Download the latest disk image. Double-click it and a window will open with the Tunnelblick icon and the words “Double-click to begin”. Control-click the Tunnelblick icon and click “Open” to begin installation.

Reinstalls, upgrades, and downgrades will be recognized and the old version of the program is moved to the Trash before installing the new version.

Start Tunnelblick by double-clicking it in Applications. It will step you through the process of setting up configuration files. When Tunnelblick is running, it will display the Tunnelblick icon in the status bar at the top of the screen on the right. Usually, the icon is located immediately between the time display and the Spotlight icon. Click on the Tunnelblick icon to reveal the Tunnelblick menu, then click on a configuration to connect using it, or click on “VPN Details” for a window with details for each configuration.

Each time Tunnelblick is launched, it checks for updates automatically if that was specified when Tunnelblick was installed and displays a notice that an update is available. It also checks every week if it is running for more than a week. If automatic checking for updates is not enabled, there are three ways to update Tunnelblick manually:. All configurations and preferences will be used by the new version even if it is a “deployed” version. If an update is available, you will be guided through the update process.

If you install an update, your old version will be moved to the Trash. If you don’t see an “Options You’ll need to download the version you wish to use stable or beta and follow the ” How do I install Tunnelblick?

OpenVPN needs root privileges because it needs to modify network settings when configuring network devices, changing routes, and adding and removing nameservers. Because we don’t want you to enter your computer administrator password every time you start a VPN connection, Tunnelblick comes with the “openvpnstart” setuid root binary that allows you to do exactly one thing: start a VPN connection with super user rights.

Tunnelblick also needs root privileges to secure configuration files. This is a security issue. If the configuration files were owned by the local user, anyone could execute arbitrary code as root by inserting an ‘up’ directive to the configuration file and pointing it to a malicious shell script.

Therefore, when a configuration file is first used, Tunnelblick asks for a computer administrator’s username and password and uses them to change the ownership of the configuration file to root, so it is protected against unnoticed and possibly malicious changes. If new configuration files are added, Tunnelblick will ask for a computer administrator’s username and password to change the ownership of the new file to root before the first use of each new configuration file.

You are probably using the ‘user’ or ‘group’ directive in your OpenVPN client configuration file. If you use it, the OpenVPN process will drop privileges after startup which is additional security measure. However, OpenVPN needs root privileges for restoring the route back to their original state. In short: don’t use it. Tunnelblick contains the “openvpn-down-root. Together with a per-configuration preference, this allows the use of ‘user’ and ‘group’ but it does not allow OpenVPN to restore the routes.

See Using Tunnelblick for details on how to do this. Under certain circumstances, checkboxes or buttons may be disabled and will appear dimmed — nothing happens when you click on them. Buttons and checkboxes are disabled when they cannot be used. Examples from the VPN Details window : – “Monitor connection” is disabled unless “Set nameserver” is selected, because “Set nameserver” is required in order to monitor the connection. This is because you cannot directly modify them without administrator approval.

To modify them, select “when Tunnelblick launches” which will require an administrator username and password , change the settings to be the way you want, then select “when computer starts” which will again require administrator approval.

Tunnelblick contains multiple versions of OpenVPN. If you don’t find an answer, try the Tunnelblick Discussion Group. What is Tunnelblick? Explanation 1 : Tunnelblick is a program that can be used to securely connect a Mac running macOS or OS X to a remote network or the Internet, bypassing untrusted networks, censorship, and eavesdropping.

When you connect through a VPN, your computer sends all network traffic through a “tunnel” to the VPN server, which then passes on your network traffic to a local network or the Internet. It is as if you were connecting to the network or Internet through the VPN server instead of your computer.

All traffic between your computer and the VPN server is encrypted. What else you need depends on your situation: If you have a “deployed” version of Tunnelblick usually from a company or VPN service provider , you may not need anything else — everything is usually included in the customized version of the Tunnelblick application that is distributed. Otherwise, you need either a “configuration file” or enough information about the VPN to edit the sample configuration file that Tunnelblick will offer to install.

You will probably also need certificate and key files for encryption. Your company or VPN service provider should provide them. See Connects to the VPN, but doesn’t work. See Verifying downloads.

See Uninstalling Tunnelblick. Just install the earlier version. Tunnelblick needs root privileges the first time it is run for two reasons: It modifies ownership and privileges on parts of the Tunnelblick application itself to make it secure; and It installs a system “daemon” so it can start OpenVPN as root and perform other operations which require root access, such as loading Tun and Tap system extensions.

You are using an older version of Tunnelblick which doesn’t implement that checkbox or button; or You are using a “deployed” version of Tunnelblick, and the deployer has specified that that checkbox or button should not be available; or The button has a different label because it is being used for different purpose. Examples: There is one button which displays “Edit configuration” or “Examine configuration” depending on whether you can edit modify the configuration, or only examine it.

To edit a configuration, you must have write permissions on the folder which contains the configuration, and must be able to write to the configuration file. Non-administrator users of “Deployed” versions of Tunnelblick may be prevented from editing configurations by the deployer.
