iTerm2 and ohmyzsh setup for macOS Monterey - 2022

Screenshot 2022-07-10 at 8.35.11 PM.png


  1. Download and install iTerm2
  2. Most of the versions of MacOS comes with zsh preinstalled, check if you it already
    • zsh --version
  3. If the above step fails, install `zsh`, check step 4 if you don't have brew installed and come back to this step.
    • brew install zsh
    • Follow the instructions from the output of the above command
  4. If you don't have brew then follow these steps to get brew installed first
    • /bin/bash -c "$(curl -fsSL"
    • You mostly have to run these steps after brew install, please check the output of the above command as well, I am focusing on M1 Silicon chips,echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/mahendra/.zprofile 11 eval "$(/opt/homebrew/bin/brew shellenv)"
  5. Now install ohmyzsh

Now comes the good stuff

Heads up we will be setting up most used Powerlevel10k theme

  1. Let's install the recommended font
  2. Install Powerlevel10k for Oh My Zsh
  3. You can run, source ~/.zshrc on your terminal to start configure powerlevel10k theme.
    • you can also call p10k configure change the look and feel
  4. Go to iTerm preferences > Profile > Colors to further change the colour profile, there are some default colour themes available. You can also download more presets from here and load them.


We will add some list of plugins that will help with some tools used daily to boost productivity. Please be mindful of how many plugins you add as more plugins means more time it takes to start the terminal. Pick and chose the right ones for your shell.

We will start with yarn, just add yarn to plugins section of .zshrc file,

plugins=(git yarn)

Autojump - a faster way to navigate the filesystem

Directories must be visited first before they can be jumped to.

brew install autojump

Go through the output of the above command, you might have to add a line to your .zshrc file, the example below works for M series MacBooks only:

[ -f /opt/homebrew/etc/profile.d/ ] && . /opt/homebrew/etc/profile.d/

Auto-suggestions while you type a command

Run the following command to clone th repository into $ZSH_CUSTOM/plugins(by default~/.oh-my-zsh/custom/plugins)

git clone ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Add the plugin to the list of plugins for Oh My Zsh to load (inside~/.zshrc):

    # other plugins...

Syntax Highlighting

Run the following command to clone th repository into$ZSH_CUSTOM/plugins(by default~/.oh-my-zsh/custom/plugins)

git clone ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
