Error compiling for board Adafruit Bluefruit nRF52832 Feather.

It is probably due to the pre-built adafruit-nrfutil cannot run on your Mac. The binary is generated on MacOS 10.13, if

your Mac is older than that. Please update your macOS, or you could follow this repo's readme

here https://github.com/adafruit/Adafruit_nRF52_nrfutil to manual install it ( tried with pip3 first, or install from source

if it doesn't work). Then use the installed binary to replace the one in the BSP.
