Message: "Missing Driver..." when connecting to Norton Secure VPN on Mac

This problem can happen if the remnants of a previously installed VPN service are still present on your Mac. Make sure that you completely uninstall and remove other VPN software if still installed.

If the problem persists, manually remove the TUN or TAP kexts (device drivers) that are no longer needed.

Manually remove the TUN or TAP kexts of other VPN services

  1. On the Apple menu bar, click Go > Utilities.

  2. In the Utilities window, double-click Terminal.

  3. In the Terminal window, type the following and hit enter:

    sudo kextstat | grep -i tun

  4. Type your administrator password and hit enter.

  5. In the Terminal window, kext details are displayed. Make a note of the TUN or TAP kexts found on your Mac.

    For example, in the following details, 'foo.tun' is the kext name.

    115 0 0xffffff7f81968000 0x6000 0x6000 foo.tun (1.0) <7 5 4 1>

    Following are a few common TAP or TUN kexts:

    • net.tunnelblick.tun and net.tunnelblick.tap

    • foo.tun and foo.tap


    • com.viscosityvpn.Viscosity.tun and com.viscosityvpn.Viscosity.tap

    • com.pogoplug.xcetun

  6. In the Terminal window, type the following and hit enter:

    sudo kextunload -b foo.tun

    Replace 'foo.tun' in the above command with the kext found on your Mac in line 4.

  7. Exit Terminal, and restart your Mac.
