How do I uninstall the Cisco VPN Client for Mac OS X?

The Cisco VPN Client on Mac OS X systems must be uninstalled by running a script via a terminal window. This may be useful to you, particularly if you now wish to use the built-in VPN client for OSX ( http://www.bol.ucla.edu/services/vpn/pptp/docs/macosx.html ):

Please follow the instructions below:

1. Navigate to the following: Mac Hard Drive → Applications → Utilities
2. Start the ‘Terminal’ application.
3. Paste the following command into the Terminal window and hit enter:

sudo /opt/cisco-vpnclient/bin/vpn_uninstall

4. Follow the instructions to remove the VPN Client and close the terminal
application when it has finished.

NOTE: You will need have the admin password for your computer in order to run the script.

The above path is incorrect here are the correct instructions from Cisco’s web site;

The VPN Client uninstall script uninstalls any previous command-line or GUI version of the VPN Client from your workstation.
