VNC connection to iMac results in black screen
I am running Monterey 12.1 on a 21.5-inch, 2017 iMac. I've enabled Remote Management and within this enabled screen sharing via VNC.
When I connect to this iMac via a remote VNC viewer client all I get is a black screen on the viewer. Also, the mouse pointer on the iMac, which I have enlarged via the Accessibility System Preferences pane, reverts back to the iMac original size. I have to go back to the Accessibility pane and reset it to the size I had previously set.
This behaviour indicates to me that the VNC viewer connection has some connection to the iMac if the iMac's mouse pointer size is changed. However, there is no desktop or any other function being passed back to the VNC viewer client.
