I’m having a weird issue where my OP1 won’t power up if it’s plugged in to either an apple adapter or a powered USB hub. Haven’t tried it through my newer MacBook yet, since I don’t have a USB-C adapter with pass-thru charging.
Even after unplugging it, I have to try TE boot (sometimes a few times) to get it to power up. Once it’s on, I can plug it in and it appears to charge just fine.
I wish there was an option from the TE boot screen to continue to a normal start up.
I noticed something similar last night – I plugged the OP-1 into my iPad Pro charger (it outputs 1A instead of the older 0.5A chargers) and not long after the parameter knobs stopped having any effect when turned. I turned it off and back on, but it didn’t come back to life until I unplugged the USB cable.
