[Microbit-Python] Can't get MU to run on MACbookAir

[Carlos P.A.]

Hi Robert,

MicroPython is a reimplementation of Python 3 that primarily targets
microcontrollers. It is possible to install Micropython on macOS or Linux,
but for the microbit you run MicroPython directly on the target, not your
PC.

What MU does is pack your Python script together with MicroPython for the
microbit and then loads that into the microbit itself. When you click on
the REPL, that is a connection to the microbit and the code you type and
excute there is sent to the microbit with the results sent back to your
computer.

If you would like to run a Python script on your computer that talks to the
microbit, there is a project called microperi (
https://github.com/JoeGlancy/microperi) that implements a Python module
that replicates the same API that the microbit has. However, please do not
confuse these two different approaches, as the general microbit MicroPython
approach is to run micropython on your microbit, not your PC.

Regards,
Carlos
