If you upgrade to macOS 27 (Golden Gate) and your LDK dongle (HardKey license) is no longer recognized, falling back to a software key license, this is a known issue: Rosetta 2 is not installed by default on macOS 27, and the Sentinel LDK driver still requires it.
To fix it, open Terminal and run:
softwareupdate --install-rosetta --agree-to-license
Then restart IMC.
