On Macbook Pro 15″ and 17″ (Late 2010, Early 2011 – the one with Thunderbolt port) sometimes kernel panics whenever Cisco AnyConnect establishes connection.

Usually the Panic comes approx 30 seconds after a connection is established.

I found out that the following solves this issue :


If your macbook kernel panics, reboot it.

– close all apps

– shutdown macbook from menu.

– Make sure the powercord is in

– Reset the SMC by pressing Shift+Crtrl+Alt + Power button for at least 5 seconds

– Startup the macbook

– Connect using AnyConnect.


This has worked for me so far. It’s not optimal, Cisco should definately fix their client, but this is a way to at least be able to connect.
