seeing this error when I am trying to install my network extension: _macvnodechecksignature: /Applications/abc.app/Contents/MacOS/abc: code signature validation failed fatally: When validating /Applications/abc.app/Contents/MacOS/abc:   Code has restricted entitlements, but the validation of its code signature failed. Unsatisfied Entitlements:__ I have set the right entitlements as far as I know . is this error about entitlements or signature that is not obvious from the message . this is sseen on Catalina 10.15.6 the macOS Network extension is Developer ID signed . still facing this error . any idea what will fix this error ??

i have basic question . I need to comunicate data / message between a System Extension and application (this is not the container app for System Extension ). which IPC mechanism is recommended ? is socket communication good for the same ?

After using OSSystemExtensionRequest deactivationRequestForExtension for Network Extension and after a reboot the extension is still seen with the status "uninstalling" so it looks like we require 2 reboots for deactivating the Extension. is it a known behaviour for system extension? how to achieve this with only 1 reboot programatically (not via systemextensionsctl reset) ?
