MAC iTerm2 + Oh My Zsh terminal installation tutorial

As a powerful terminal that every developer has, why wouldn’t you?

Without further ado, let’s get to installation.

Install the ZSH

Be sure to run ZSH –version first to check whether ZSH is installed.

Information similar to ZSH 5.7.1 is displayed indicating that you can skip ZSH and install iTerm2 directly.

macOS

The latest macOS comes with ZSH built in, so you probably won’t need to do this.

To install Homebrew, visit: brew.idayer.com/.

brew install zsh
Copy the code

Set to default:

chsh -s /usr/local/bin/zsh
Copy the code

For more details about how to install a platform, see Installing-zsh.

Install iTerm2

ITerm2 is a more powerful alternative to terminals on the macOS platform and currently supports macOS 10.14 and later.

You can download iTerm2 directly from the official website.

Set iTerm2 as the default

Find options: iTerm2 -> Make iTerm2 Default Term
