What I do with fresh Macbook first

Install Homebrew

Homebrew is a free and open-source software package management system that simplifies the installation of software on Apple's macOS operating system and Linux. The name is intended to suggest the idea of building software on the Mac depending on the user's taste. - Wikipedia

Install zsh

ZSH, also called the Z shell, is an extended version of the Bourne Shell (sh), with plenty of new features, and support for plugins and themes. Since it’s based on the same shell as Bash, ZSH has many of the same features, and switching over is a breeze.
