• I became aware this evening that AnyConnect has compatibility issues with MacOS Catalina. I upgraded my OS because I figured the bugs had been worked out with the transition to a fully 64-bit system. I’ve upgraded AnyConnect to the lost current release with no luck. Uninstalled and tried a couple of earlier versions of 4.8.xxxx, still no go.
• The current version of the Cisco AnyConnect client available through WebStore (4.9.04053) is officially supported and compatible with Mac OS versions that support 64-bit applications including Mac OS versions 10.13 (High Sierra), 10.14 (Mojave), 10.15 (Catalina), and 11 (Big Sur).
• Cisco AnyConnect broken on Catalina. The fix ended up being a new version of AnyConnect by Cisco. Posted by PTVMan. Cisco IPSec and others are available in macOS by default by adding a VPN interface in Network Preferences.
