Pico, Breakout Garden and Development on MacOS

Hi everyone,

I am struggling to find direction on how to get started with development using a Pico and the Breakout Garden. I am using macOS Ventura (I know about the Ventura problem, and have successfully flashed it with the Pimoroni firmware).

I can upload scripts to the Pico using Thonny, which work fine. My guess is it is to do with enabling I2c serial communication on macOS?

Appreciate any help!
