Use openconnect instead of Cisco AnyConnect
If you need to use the Cisco Anyconnect client for using your school's vpn, you can use an open source and much lighter weight client called openconnect - MIT recommends using it in their IT documentation.
To install on macOS:
- Install openconnect
brew install openconnect - Install the macOS TUN/TAP driver
I had no problems using it, other than not being a student anymore!
