Home Assistant Core terminal

Hello world!

This is my first question and I would really appreciate your help. So Im clueless to this all new world but I’m learning . I installed home assistant on my old Mac and its working just fine, the I installed it through Python therefor I’m missing a lot of features. I’m wondering if its possible to do the following:

  1. install HACS
  2. Add ons
  3. how to get into the terminal? is it possible to install SHH terminal?

Thank you!
