Just bought a mid 2012 Mac Pro desktop. When I connected the display to the mini port, the screen remained black. When I connected it to my Macbook pro mid-2012 it works fine. I don't know how to tell if the monitor is Thunderbolt or not. Can someone please advise me?
Thanks, Joel Williams
Mac Pro, OS X El Capitan (10.11.2)
With the display connected...
On your Mac click your Apple menu top left in your screen.
From the drop down menu click About This Mac > System Report.
If it's a Thunderbolt Display you will see Thunderbolt under Hardware just above USB.
The Thunderbolt monitor has the cable permanently attached to the monitor and has a Thunderbolt receptacle on the monitir together with Ethernet, FW 800 and three USB ports.
The plug should have lighening icon at the end. A mini displayport plug has a monitor screen icon. It also has a MagSafe cable to charge a Mac laptop
How do I tell if my 27" monitor is Thunderbolt?
