After I had studied the part 2 of the series Hands On Ableton Live, I was thrilled by the content. Nils Hoffmann, the points sympathetic, comprehensible and always with reference to the practice is good, his way of speaking, in particular the choice of breaks -. Middle - in - set - is at times getting used to, but it runs on a matter of taste and is certainly not an objective evaluation , So it's more important what he says than how. All in all, part 2 So the reason for me to order part 3. Only unfortunately I had to find that part 3 not running on Mac OSX receipt. Part 2 did so easily. To verify that it is on the computer, I then found in 2 other systems tried (2x OSX 10.9, 1x 10.10) - always with the same result: The application shuts down soon after it starts itself Thus I can not review the content.. The DVD goes back, so I can not do anything. Too Bad.
