Mac Cinema Display as a second display for my iMac 2015 21.5 inch
I am trying to use this Mac Cinema Display as a second display for my iMac 2015 21.5 inch and it has two thunderbolt 2 plugs and four usb's. The second display has 3 cables that I am not sure that I need to plug into my iMac. What cables do I need to plug in? I need to know this so I can get the correct adapters. Thanks.
