Dropping Mavericks was premature. Is Steinberg aware that Apple in their infinite control freakery will not allow an upgrade to Yosemite anymore? So if we upgrade to El Capitan we cannot use our Steinberg hardware MR816s because Steinberg has not made working drivers yet (will they? Who knows? Not the customers who provide Support for Steinberg).
A DAW without inputs and outputs is a curiousity.
