Zsh contains many of the same features that Bash does since it is built on the same shell, and moving over to it is a simple process. Actually, if you have macOS Catalina beta or later, your Mac already uses zsh as the default shell in Terminal, thus you won’t need to transition.

However, for those who still have Bash on their Macs, we will present today multiple ways to install and use zsh as well as Oh My Zsh on Mac.

What Is the Difference Between Bash and Zsh on Mac?

Bash is a command-line interface shell application that is used to a great extent in both Linux and macOS. When a user wants to operate their computer without having to navigate the menus and windows included inside a GUI, they will utilize Bash.

Zsh, commonly known as the Z shell, is an enhanced version of the Bourne Shell (sh). Which includes support for plugins and themes in addition to a plethora of brand-new features. It is both more interactive and more configurable than bash.

Unlike bash, zsh has support for floating-point numbers, offers spelling correction and approximate completion, provides support for hash data structures, and way more. And like we said, starting with macOS Catalina, it is the default terminal shell. You can check which terminal shell you have by typing the echo $0 command.

Zsh is a type of Unix shell that may serve both as an interactive login shell and as a command interpreter for shell scripting. On the other hand, Oh My Zsh is an open-source platform for managing your zsh setup.

It comes pre-loaded with a variety of enhancements to the zsh shell, such as functions, themes, and plugins. Oh My Zsh is by far the most popular and user-friendly zsh framework available, and we’ll show you how to install and use it on your Mac.
