Cisco Anyconnect: "Posture Assessment failed: Unable to load the CSD library" on Macbook Pro, M1 pro chip

Question

I used anyconnect-macos-4.8.01090-predeploy-k9.dmg to install anyconnect, it only works once after I install it. (I will then connect to my company's VPN, before that it will automatically upgrade itself to version 4.10.04065 after installation, then the connection is successful).

However, once I disconnect it, subsequent connections will always fail.

Any idea how to resolve this? my Mac: MacBook Pro (16-inch, 2021), M1 Pro chip

Answer 1

Steps that worked for me:

1. Open Finder
2. Within Finder, on the top right, search for "Cisco"
3. Right-click on the Cisco AnyConnect Client
4. Click "Get Info"
5. Tick the checkbox "Open using Rosetta"
6. Quit & restart AnyConnect, it should work again.
