Sometimes I leave work open on my iMac and need to use Screen Sharing from my Macbook to make a few changes. This works great except when my wife and baby are sleeping in that bedroom.
I understand that using Apple Remote Desktop it's possible to open a session as a different user with a 'virtual display', showing nothing on the hardware display and (I assume) not waking it if asleep.
That's almost what I want, except that I want to control the existing logged-in session. If it weren't an iMac I could just physically turn the monitor off when I leave.
Can Apple Remote Desktop control the existing session without turning the screen on? If not, is there another tool that can?
