I have installed firmware and usb flash (latest compatible versions) on my Mackbook Pro Retina 15" using the latest High Sierra OS.
TotalMix is not showing its interface so I cannot start routing my setup. I have tried un- and reinstalling software - nothing happens.

A goog friend, a long time power user of Fireface adviced me to run everything through my USB-3 Mac route. The Mac sports two USB 3.0 ports, two "Thunderbolt 2" ports, an HDMI port, an audio in/out port, and an SDXC card slot.

Is this a cable problem or... Any suggestions?
