I have a 27" cinema display mini dvi type connected to a 27" imac (late 2012, Latest model)
The problem I am having is everytime I turn my IMac on I have to completly unplug my cinema display from my IMac.
If I dont the cinema display will not start.
This problem has only happened since I upgraded from an old 27" IMac to a new one
Any help would be greatly appreciated
Which cable are you using & from which port on the Mac?
I am using mini dvi to thunderbolt
Hope this helps
