Connecting Cinema Display with mini display port to macbook pro with thunderbolt port
I am trying to connect a 27" cinema display (2010) that has a mini display port cable out of the back, into my macbook pro (2013) with thunderbolt ports. The mini display port cord fits into the thunderbolt port on the Macbook Pro, however the macbook pro does not detect the cinema display and the cinema display does not have any picture on the screen. The USB plugs in fine and sound comes out, and I have the adapter for the magsafe to magsafe 2 and that works fine, it just the actual display. Any help would be appreciated!
Thanks!
MacBook Pro with Retina display, OS X Yosemite (10.10.1)
