There was a problem hiding this comment.
I was not able to get this to work on a Mac.
First, following "Install Zephyr SDK" at https://docs.zephyrproject.org/latest/develop/getting_started/index.html gives the following output:
Installing host tools ...
SKIPPED: macOS host tools are not available yet.
Proceeding anyway:
$ west build src-gen/HelloWorld -t run

I found this page: https://learn.adafruit.com/blinking-led-with-zephyr-rtos/installing-zephyr-osx#installing-the-development-toolchain-3056482, which isn't quite right, but the following partially worked:
brew install --cask gcc-arm-embedded
However, this puts the tools in /opt/homebrew and the above command seems to still look for them in /usr/local. Suggestions?

Hi Edward. I have verified that this works on my macOS Ventura. The error seems to be that it doesn't find the SDK that you have installed. This is the output from my machine:
This should not be necessary though... |

Yes, I did all these things. I initially tried putting the SDK installation somewhere other than /opt, but moving it there doesn't help. Note that west seems to be looking in |

That is very strange. Can you try to deleting the build folder between these builds? |

The problem you are experiencing Edward seems specific to your system. I am able to follow this guide on my MacBook and another person was also able to do it on his MacBook: lf-lang/lingua-franca#2064. I will merge this PR since the docs are now out-of-date with |

I am sorry for the all the Zephyr updates. Here is my final proposal which I think is quite macOS compatible also
