I have a lab of 25 iMacs (Mid 2011, 12,1 Model).
They are all running OS X 10.11.6 and ARD Version 3.8.5
Our Lecturer Shares his screen to all these iMacs from his MacBook Pro
The screen is shared to all iMacs however it does not work permanently.
Anywhere between 3 and 15minutes the screen sharing shuts itself down and the lecturer needs
to refresh his List of iMacs in ARD and then share the screen again.
Has anyone experienced this problem at all?
