How to manually uninstall the Cisco client on a Mac

• Installing a new version fails — for example it says a newer version is already installed, or the installer quits halfway.
• An old AnyConnect from a previous employer or school is still on the Mac, carrying someone else’s server settings that clash with what you need now.
• You deleted the icon from Applications, but a Cisco icon is still in the menu bar or the client still runs after startup.
• The client will not open or crashes on connect, and reinstalling did not help.

The Cisco client ships with its own uninstaller. In most cases this is all you need.

1. Disconnect, then quit the client from its menu-bar icon.
2. Open Finder → Applications and go into the folder named Cisco.
3. Double-click Uninstall Cisco Secure Client; on the older 4.x release it is called Uninstall AnyConnect.
4. Enter your Mac login password when asked and wait until it reports that the uninstall finished.
5. Restart the Mac. If the Cisco folder is gone from Applications afterwards, you are done and can ignore the other two cases.

The graphical uninstaller only runs a script for you. When it is missing or does nothing, run that script directly; the result is the same.

1. Open Terminal: press Command + Space, type Terminal and press Return.
2. For the current release (Cisco Secure Client 5.x), paste this line and press Return: sudo /opt/cisco/secureclient/bin/vpn_uninstall.sh
3. For the older release (AnyConnect 4.x), use this line: sudo /opt/cisco/anyconnect/bin/vpn_uninstall.sh
4. Terminal asks for your Mac login password. Nothing appears on screen while you type — that is normal; type it and press Return.
5. If you get “No such file or directory”, that release is not on the Mac or is already partly removed — try the other line. If both lines fail, you are in case 3 — continue with the next section.
6. Restart the Mac when the script finishes.

If neither the uninstaller nor the script can be used, or a fresh install still fails after using them, delete what Cisco left in the system yourself. Every command below touches only Cisco’s own folders. Copy and paste each line whole; do not edit the paths or add spaces inside them.

If the Cisco folder is still in Applications and contains an app with Socket Filter in its name, drag that app to the Trash in Finder first. Removing it this way also makes macOS remove the network extension it installed; deleting it with a command does not.

1. Open Terminal: in Finder go to Applications, open the Utilities folder inside it and double-click Terminal. Paste each command below and press Return; the first one asks for your Mac login password (nothing appears while you type).
2. Remove the program itself: sudo rm -rf /opt/cisco/secureclient /opt/cisco/anyconnect
3. Remove the folder in Applications: sudo rm -rf /Applications/Cisco
4. Remove the launch items of the background service (run both lines): sudo rm -f /Library/LaunchDaemons/com.cisco.secureclient.* /Library/LaunchDaemons/com.cisco.anyconnect.*
5. sudo rm -f /Library/LaunchAgents/com.cisco.secureclient.* /Library/LaunchAgents/com.cisco.anyconnect.*
6. Remove your personal settings (saved server addresses live here; you will have to enter them again): rm -rf ~/.cisco ~/.anyconnect

macOS keeps a record of which version each installer package put on the Mac. With the files gone but the record still there, the installer keeps claiming that a newer version is already installed and refuses to run — so always do this section after removing files by hand.

1. List the Cisco receipts in Terminal: pkgutil --pkgs | grep -i cisco
2. It prints a few names starting with com.cisco. Run the following once per line, replacing the name at the end with that line: sudo pkgutil --forget com.cisco.pkg.anyconnect.vpn
3. Run the first command again; when it prints nothing, the receipts are gone.

• Restart the Mac. The background service only disappears completely after a restart.
• No Cisco icon in the menu bar and no Cisco folder in Applications means the uninstall is clean.
• To double-check, run this in Terminal; “No such file or directory” is the answer you want: ls /opt/cisco
• Download the macOS installer from our Cisco page and install again. On the first connection macOS asks you to allow a network extension once more — that is expected; follow the guide on the macOS network extension permission.
