hi, i recently bought this to run my new Mac Pro 2013. i tested it using a Macbook Pro Retina with HDMI. I must say, I was pretty impressed by the brightness and the clarity. the only thing that sucked was that there was a dead pixel in the first one that I received, but Monoprice sent me another one, and had me send the old one back. It was pretty easy. I also bought HDMI cords from them. Overall, I am excited about my Mac Pro whenever it decides to get here. The base of the monitor is kind of ugly, but I mounted my 27" screen to a VESA arm, which makes it look a ton better...
