I have been using screen sharing for some times to access computers around the office. Lately (maybe after updating to Sequoia?) when I connect to computer B from computer A, the screen on computer B goes dark and I have to break the shared connection to access the screen on computer B directly. Is there a way to keep the main screen (and mouse and keyboard) enabled on a computer that is being shared?
Thanks.
MacBook Pro 16″, macOS 15.6
OK, updating the Sonoma machine to Sequoia seemed to do the trick. Maybe there was some Sonoma-Sequoia conflict. Thanks for the suggestions!
I just tested two other Mac's from my main Mac running Sequoia 15.6 (an older Mac running Catalina and a new Mac running Sequoia 15.6) and could not reproduce a blank screen on either of those.
At this point, I suggest restarting both computers and then re-test Screen Sharing.
Long shot.. on A, take the shared B's window out of Full Screen Mode.
I'll do some testing after lunch and get back to you.
Until then, see "Set screen sharing and Set view options" at > Share the screen of another Mac - Apple Support
Unfortunately, I a not in full screen mode. I also think this is intentional on Screen Sharing's part. If I click the mouse on the controlled computer (with the dark screen), a computer voice announces that this computer is being controlled remotely and to hit the ESC key to close the connection. I am pretty sure I used to be able to interact with the host computer (B) on the main screen (and moue/keyboard) and the remote computer (A) at the same time.
The application is called screen sharing not screen stealing!
I did some additional testing with a 3rd computer (computer C ) and was not able to reproduce. So computer C can connect to computer B and computer B's screen remains ok. Computer A connects to computer C and C's screen remains. I'll upgrade computer B to Sequoia (I just realized it was still on Sonoma) and see if it magically goes away...
Good work, thanks for reporting the solution. You're welcome.
