Any videos available how to setup a development environment on a Mac?

HI,

because I need to test my PR… I am pointed to https://developers.home-assistant.io/docs/en/frontend_development.html and hence to https://developers.home-assistant.io/docs/en/development_environment.html site

This assumes so much base knowledge of the development Lingo, I feel somewhat lost. Now I do have a spare Mac lying around, so would love to try to set the up as testing environment. And have setup Homebrew as instructed https://developers.home-assistant.io/docs/en/development_environment.html#developing-on-macos.

Id need some help going on. Anyone know of some informative videos on the subject please?
thanks
