• OS : macOS High Sierra
• Terminal : iTerm2 (Build 3.2.1beta4)
• Font : Meslo LG L DZ Regular Nerd Font Complete (Size: 14pt)
• Color scheme : Material Design

Working terminal:

Homebrew/macport should be installed. If not then install the lates version of homwbrew.

iTerm2 is way better than OS X terminal. I would also recommend to install shell integration for it.

After installation of zsh, set it as login shell in iTerm2. You may need to run this command: chsh -s $(which zsh). Logout from iTerm2 and then again launch it. Type echo $0 and you will see zsh. You can also use macports to install the zsh.
