Nope, didn't do anything special to the non functional or the connected macbook I used to update the firmware. I used a USB-C to USB-C cable that came with an (original) charger.

will try again. but every time i connect cable it says " Cannot Use Thunderbols accesory. Thunderbolt accessories are not supported on this Mac."
