抜粋
----------------------------------
AnyConnect 4.9.04043 New Features
This AnyConnect 4.9.04043 release introduces support for macOS 11.x (Big Sur) and compatibility with devices running Apple Silicon. It also resolves the defects described in AnyConnect 4.9.04043.
When running on macOS 11, AnyConnect uses a system extension, as opposed to the kernel extension used in previous AnyConnect versions.
Prior AnyConnect versions may still work on macOS 11, but only on MDM-managed devices, since an MDM-based approval of the AnyConnect kernel extension is required starting with macOS 11. Refer to AnyConnect macOS 11 Big Sur Advisory for AnyConnect changes related to macOS 11 (Big Sur).
AnyConnect HostScan Engine Update 4.9.04045 New Features
This AnyConnect HostScan 4.9.04045 release provides official support for macOS 11.x (Big Sur). It includes updates to the OPSWAT engine versions for Windows, macOS, and Linux.
If you are using the macOS Big Sur beta or the official macOS Big Sur (version 11.x) release with HostScan, the AnyConnect HostScan Posture Module (if previously installed) on the endpoint and the HostScan PKG on the ASA must be upgraded to 4.9.04045 or later.
