The DVD burner is recognized by OS X 10.8.3 with no problems, the reading of media also runs without problems. With "Toast 11" I succeeded, however, no DVD burning, the speed was always very slow and the burning process never successful. With "Burn" but I had no problems here were the DVDs with maximum speed, described in my case 8x.
For just 10 euros for me right here the value for money absolutely.
