This is related to the tool ShowSettings (SettingsTool). This is used to check the install, state, etc., of the SEP Mac Client. It is incompatible with the latest version of the SEP client.


Release : 14.3 RU2


The tool was provided to third-party NAC vendors so they could incorporate it into their host integrity checks; see How to determine if Endpoint Protection for Macintosh is installed and running. Find out vendor using it in the environment and see how they are running it, and remove/disable it from running at all.
