I just bought the Fireface UC, installed the newest driver on mac, set the hardware setting to A.P by double clicking the knob.

Still host button is red, Fire face USB Setting only flashes when I try to open it and Total Mix doesn't let me open a new mix window

Ableton recognizes the UC, so USB-cable should work, but I can't get any sound through obviously

Please help, can't manage to find a solution through forums

My setup:
Macbook 2017, 15" A1707
Mac OS Sierra 10.12.5
2,8 GHz Intel Core i7
16 GB 2133 MHz LPDDR3
Intel HD Graphics 630 1536 MB

DAW: Ableton
