Qu series Mixer High Sierra

Stop don't upgrade to high sierra.

There was already a restart glitch between the two before this upgrade. Now you will have to completely setup the QU with logic and it will still have the restart glitch which means you may have to completely redo everything every time you turn off your mixer. Allen Heath has not done an upgrade for this as of today.

I hope I didn't tell you this too late. Too late for me luckily i have the older os on another of my 4 internals.
