MacOS 26.1 Unable to Cancel to Screen Share on Host Machine

[smithdr]

Hello:

I am using the MacOS 26.1 on a M3Ultra Studio. I frequently use M1Max MBP operating under MacOS 15.6.1 to connect to the Studio via High Performance Screen Sharing. In the past, when the Studio was operating under 15.6.1, I was able to select the esc button on the Studio to cancel the screen sharing connection from my M1Max MBP. However, since I have upgraded to MacOS 26.1 on the Studio I am no longer able to cancel the screen sharing connection on the Studio with either the esc or CMD+OPT+ESC. With MacOS 26.1, the only way I am able to close the screen sharing connection is to cancel it on the M1Max MBP.

Does anyone know how to cancel a screen sharing connection when the host machine is operating under 26.1? Or, is this a new feature or bug in 26.1?

Thank you in advance.

You're asking if there is a way to close a screen sharing connection from the host, rather than the client. I just connected from my MacBook Air to my Mac Mini, both on 26.1 and I don't see any way to disconnect from the Mini, without turning off sharing in System Settings.

This is exactly what I am asking. In my instance, I cannot even get into the host with the keyboard/trackpad--the hosts monitor is blacked out when the client is connected via screen sharing. This is new behavior with 26.1. In the past, when the host was on 15.6.1 I could hit the escape key and cancel the clients screen sharing connection.

So you are like an admin, and want to kick others off? From your own account, I think you’d have to turn screen sharing off.

I am the administrator. In 15.6.1 I never had to go into settings to turn off screen sharing. All I had to do was hit esc on the host computer to cancel screen sharing. Besides, I can't even get into settings on the host computer to turn off screen sharing until I cancel screen sharing in the client.
