Thanks so much for replying.
As far as I have understood, there is no solution on the way. What I cannot understand is how Reloop could release this product in 2013 with such a problem, taking into account the Macs have the USB 3.0 since 2012 and the problem was already known from Jockey ME.
At least Native Instruments announced they are working close with Apple to fix the S4 as soon as possible, but Reloop says nothing.
I need to think about it because I would really like to get the Mac but I really dont like the hub because that means an extra device plus cables plus an extra plug . There ase still many Pcs which come with one USB 2.0.
If somebody else has any other idea/oppinion please let me know.
Thanks!
