I used to work in a role where I used Cisco AnyConnect on my personal MAC to access my work VPN - this was years ago now. Following the uninstall process, everytime I restart my MAC I receive and "Attention Required" notification that says "Cisco System Extension Blocked: Your system requires you to enable the Cisco AnyConnect System Extension in your System Preferences in order to leverage the full extent of AnyConnect capabilities. Some AnyConnect functions will not operate correctly until the "Cisco" System Extension is enabled". It then tells me to go and click a button in System Preferences to enable.
1) I no longer even have Cisco installed, 2) I do not use/want to have cisco installed 3) there is no button to enable what it is telling me to enable presumably as I have uninstalled cisco.
How do I stop this error from popping up everytime I start my PC??
