Tunnelblick and Apple Silicon

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

Also see Tunnelblick on macOS Big Sur.

If you are using an Apple Silicon (M1) Mac, you should use the latest beta version of Tunnelblick. You should allow Tunnelblick to automatically check for updates on the 'Preferences' panel of Tunnelblick's "VPN Details" window. Be sure to put a check in "Check for updates to beta versions".

In Tunnelblick 3.8.5beta04, Tunnelblick's system extensions run as a native programs on M1 and Intel-64 processors. The Tunnelblick application and OpenVPN run as a native program on Intel-64 processors, and run under Rosetta 2 on M1 processors. We plan to make future versions of Tunnelblick run as a native program on either Intel-64 or M1 processors.
