macOS 11 Big Sur issue with UCL VPN

27 January 2021

macOS 11 Big Sur is now compatible with UCL's Remote Access VPN service. For more details see UCL Remote Access VPN client upgraded (now also compatible with macOS 11/Big Sur).

macOS 11 Big Sur has now moved into full release. ISD are working to prepare the Remote Access VPN service for compatibility with macOS 11 Big Sur.

However, there are two compatibility issues with the Remote Access VPN service for this new operating system:

  1. The current version of the AnyConnect client (4.8.01090) is not supported on macOS 11 Big Sur. We are working on testing the new AnyConnect client at the moment before deployment.
  2. Sophos have released a supported version of its anti-virus edition for Home users. This can however only be used on personal devices and MUST NOT be used on UCL-owned devices.
  3. Sophos do not yet have an available anti-virus edition of their Sophos Endpoint Protection which is the version that can be used on UCL-owned devices.

Therefore, based on the above reasons, it is highly recommend that you do not upgrade to MaOS 11 Big Sur in order to be able to continue successfully using the Remote Access VPN service. Further updates will be communicated here when they become available.

It has been brought to our attention that Sophos Endpoint protection is not compatible with the beta/preview release of macOS 11 Big Sur.

If you choose to upgrade to macOS 11 Big Sur while it is in beta/preview, and use Sophos as your anti-virus client, you will not be able to connect to the UCL VPN service.

When macOS 11 Big Sur moves into general release, Sophos will release a supported anti-virus product.
