Using the Caltech VPN Client on Mac

The Minimize on connect option will cause the client to automatically minimize after it has successfully connected.

The Enable local LAN access allows the user to access local resources (such as a printer). You may want this if you are connecting from home, but turn it off while traveling.

The Auto reconnect option will attempt to reconnect to the VPNservice if a connection is dropped.


Updating the AnyConnect client

The AnyConnect client has an auto-update feature. When new versions of the client are released, the updated clients are placed on the VPNserver. Then, when a client connects, it checks to see if there is a newer version of the client. If a newer version is found, it will download the update and apply it. You may see a window like this when you connect:

If you see this window, wait for it to finish before doing anything else. Don't interrupt the process. The installer will finish the process and the connection will proceed as normal.

Deleting the AnyConnect Client

Mac OS X users can delete the AnyConnect client by double-clicking on the Uninstall AnyConnect icon in the Cisco folder, located in the Applications folder.
