Install Homebrew on Mac

The most updated instruction can be found on their website: https://brew.sh

On your Mac, open the Terminal and paste this code:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Your mac will ask password.

Installation will take some time. At the end of the installation, this message will show:

==> Installation successful!

==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics
No analytics data has been sent yet (or will be during this `install` run).

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:

- Add Homebrew to your PATH in /Users/your_user_name/.zprofile:
    echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/your_user_name/.zprofile
    eval "$(/opt/homebrew/bin/brew shellenv)"
- Run `brew help` to get started
