Brand new Thunderbolt Display flickers a few times then goes black
When I connect my new Macbook pro retina to my new 27" Thunderbolt, the Thunderbolt Display flickers a few times then goes black. I have tried unplugging everything and replugging. All software is up to date. Super disappointing. Can anyone help?!
MacBook Pro with Retina display, OS X Mountain Lion (10.8.5)
