FWIW- I got a very nice email from Marco at M2Tech asking us to be patient. The new drivers were on the way when, according to him, Apple revised something in El Cap that made a month's worth of driver prep worthless.
I'm not saying this is true, but knowing Apple, I would not be surprised.
He says, maybe, 30 more days.
I like my little EVO (one) and I can certainly wait a month for it to be working again. You all should go through this process with Pro Tools. New, super-expensive software means new, super expensive computer control which means new super expensive studio hardware. Oh, and NO support for the few generations old of anything. This is a walk in the park compared to that. That IS a conspiracy
