As said in the title, simply plug it in and it works. But is it really surprising is mastered a technology for quite some time. I tested (27 I5 IMac OSX) Picture in the picture and "Dual Channel" function that works. But my choice is focused on this because I had a DTT signal quality problem (unwanted cuts) With double antenna, more problems. As often with mac products, it is more expensive than PC, it is already the disappointment, but realize that we will have to pay after one year for details of programs while there, c is downright shocked. Also all other functions, the types of software-sharing on Iphone / Ipad etc. are also paid. Big disappointment again. I put three stars because the product itself works, what is the minimum, but for the rest I have the feeling of being a "pigeon"
