Another developer tried to start a screen-sharing session with me on my M1 MacBook Air this morning (Sequoia 15.3). He reported however that another session was already under way on my machine. I looked in System Settings and found that the "Screen Sharing" setting was grayed out, with the notation that "This service is currently being controlled by the Remote Management service". Access to the service is disabled however, and I have no way of turning it off.
It's possible that the person who tried to help me got this session started, and that it then got aborted in some irregular way, but he see no indication of that and says there is no connection between us as seen from his end. This makes me nervous security-wise. Is there some way I can turn this off and ensure that I am not being screen-shared against my will, as it were? TIA, Howard
