Everything seems flawless on my Mac mini (Mojave OSX) with UFX.
It is just that, though the official DigiCheck app works fine, I find the NG preview version's GUI much better, and well-fitting for my iPad (using it as 2nd monitor).

One thing though, when I only run *youtube on Chrome, after some time (like 10 mins), it freezes.
I wonder what the cause is...
I put my 7/8 empty channels as my input source! (*by loopback function, hardly any latency)

Other than that, it is flawless and really good.

So just letting the team know!
