Not working on new Macbook

Have you installed the latest version of the Arduino IDE? Also try to use an real USB Adapter rather than an USB C Hub.

1.8.12 is the version I got, just downloaded it from the website today so I'm assuming that it would be the most up to date software 

Do you use an Adapter for USB or a Hub?

I've used this adapter (https://www.amazon.co.uk/gp/product/B077FY7831/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1)

and this Hub (https://www.amazon.co.uk/gp/product/B07M7642VW/ref=ppx_yo_dt_b_asin_title_o07_s01?ie=UTF8&psc=1)

When connected the Arduino does get power, the orange "L" light and the green "on" light are both lit up but no TX or RX light

Is OSC over USB enabled on Nomad? Did you use an original Arduino? Can you upload the sketch?

Yes, that seems to have solved the issue, many thanks!
