VPN, CISCO AnyConnect, Installing Cisco AnyConnect VPN for Mac OS
This page contains links to download and installation instructions for VPN software for Mac OS
University of Illinois students, faculty, and staff can use these
directions to set up their Mac OS computers or devices to connect to
the Virtual Private Network (VPN).
If you have a guest account, Technology Services recommends IllinoisNet Wireless for on-campus use. Contact your host for help downloading and installing the VPN if you need guest access for off-campus use.
Save the file at an easily findable location, such as your desktop.
Installing the VPN software
Go to the location where you saved the VPN installation package.
Double-click on the .dmg file.
The AnyConnect Installer will launch. Click Continue.
Accept the End User License Agreement (EULA) when prompted: First click Continue, then Agree.
If given a choice of which packages to install, select only the VPN item and click Continue. Depending on the installer you might not be given a choice.
The installer will estimate how much space is needed. Click Install.
You'll be prompted that Installer is trying to install new software. NOTE: This prompt is not asking for your NetID; it asks for your local user name and password on that specific computer.
Enter your local user name.
Enter your local computer password.
Click Install Software.
After the software is installed, you'll receive the message "The installation was successful". Click Close.
After installation is complete, your Applications folder will have a new Cisco subfolder containing the AnyConnect VPN.
Security Warnings
Mac OS 10.14, 10.15, and 11 (Big Sur) will warn you that the Cisco software is trying to load an extension (it might be a kernel extension or a system extension, depending on your OS and the Cisco version). In either case you need to approve this in order for the VPN software to work correctly. To do this go to System Preferences -> Security and Privacy and on the General tab you will see a notice that Cisco AnyConnect has requested to install System Software or a kernel extension and a button marked "allow". If the icon in the lower left is "locked" you'll need to click on that to unlock for changes and provide an administrator password to make the button clickable. Verify that it says Cisco AnyConnect is requesting the change, and then click "allow". Follow any other on screen directions, or dismiss any dialog boxes that say it has been allowed.
Starting the software
After you've completed downloading and installing, the Cisco
AnyConnect VPN software will be installed in the Application folder's
