Important: See The Future of Tun and Tap VPNs on macOS for information about changes to future versions of macOS.

Tunnelblick may try to load a kext to control the VPN tunnel.

Note: If you are using a 'tun' VPN, you can avoid needing to load a kext by doing the following:

  1. Make sure your OpenVPN configuration file does not include a 'dev-node tun' option;
  2. Make sure your OpenVPN configuration file does include a 'dev tun' option; and
  3. Make sure you have not selected 'Always load Tun driver' in the 'Connecting & Disconnecting' tab of Tunnelblick's 'Advanced' settings window.

The 'dev-node tun' option causes OpenVPN to use a 'tun' device, which requires a kext to be loaded. If a 'dev-node tun' option is not present and a 'dev tun' option is present, OpenVPN will use the 'utun' device which is built into macOS and does not require a kext to be loaded.

If you are using a 'tap' VPN, Tunnelblick must load a kext for your VPN to operate.

If you see the following on macOS High Sierra and higher:

Tunnelblick was not able to load a device driver (kext) that is needed to connect..

You may have encountered a new security feature in High Sierra and higher which restricts the loading of kexts (system extensions).

If the following does not help, please see Errors Loading Kexts (Device Drivers).

Cloudsee for mac. In some situations when you try to connect to a VPN, High Sierra and higher blocks Tunnelblick from loading a system extension. macOS pops up a window that looks like this:

(Tunnelblick's kexts are signed by 'Jonathan Bullard', so that's what would appear in the blocked-by-red area of the window.)

The user then has 30 minutes to allow the new system extension to be loaded. As the window notes, that can be done on the 'Security & Privacy' pane of 'System Preferences'. (The window doesn't say it, but it can only be done on the 'General' tab of that pane.) Here is a screenshot:

(The 'System software developer' in the blocked-by-red area will be 'Jonathan Bullard' for Tunnelblick kexts.)

If the user doesn't grant approval within 30 minutes, the ability to approve the kext disappears and will only reappear after trying to connect the VPN again. When that happens, the original window does not appear (it is only shown once) but the ability to approve the kext reappears in 'System Preferences' for 30 more minutes.

If the above does not help, please see Errors Loading Kexts (Device Drivers).

Tunnelblick For Mac Sierra Os

Tunnelblick helps you control OpenVPN® VPNs on macOS. It is Free Software that puts its users first. There are no ads, no affiliate marketers, no tracking — we don't even keep logs of your IP address or other information. We just supply open technology for fast, easy, private, and secure control of VPNs.

Tunnelblick comes as a ready-to-use application with all necessary binaries and drivers (including OpenVPN, easy-rsa, and tun/tap drivers). No additional installation is necessary — just add your OpenVPN configuration and encryption information.

To use Tunnelblick you need access to a VPN server: your computer is one end of the tunnel and the VPN server is the other end. For more information, see Getting VPN Service.
