MBA to iMac screen mirroring
Hi. I have my new MBA running Big Sur. I also have my old iMac running Catalina.
I'm trying to mirror the screen from my MacBook onto the iMac.
On the control centre, I click on screen mirroring.
Then, on the iMac, an icon shows on the left of the taskbar showing the window that I want to see on the iMac screen.
I click on it and I'm seeing the same screen on MBA and iMac.
Success.........BUT.
When I then try to do anything on the MacBookAir, I'm expecting to see the same thing happening on my iMac screen. It doesn't. It appears to be stuck at the point where screen mirroring started.
Any suggestions?
