Setting Up Terminal 🖥️ for Development on MacOS (Updated 2025)

If you’re setting up your MacBook for development, having a well-configured terminal is essential. This guide will walk you through installing and configuring a powerful terminal setup using Homebrew, iTerm2, and Oh My Zsh, along with useful plugins.

1. Install Homebrew

Homebrew is a package manager that simplifies installing software on macOS.

Open the Terminal and run:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

After installation, add Homebrew to your PATH by running the following commands:

echo >> ~/.zprofile
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

Verify installation:

brew --version

Check here.

2. Install iTerm2

The default macOS Terminal is functional but lacks advanced features. iTerm2 is a powerful alternative.

Install it using Homebrew:

brew install --cask iterm2

Open iTerm2 from your Applications folder after installation.

Check and Install Git

Ensure Git is installed:

git --version

If not installed, install it using Homebrew:

brew install git

3. Install Oh My Zsh

Oh My Zsh enhances the Zsh shell with themes and plugins. Install it with:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Check here.

Configure .zshrc

Edit your .zshrc file:

vim ~/.zshrc

Add useful plugins:

plugins=(git rails ruby)

The default theme is robbyrussell. You can explore other themes here.

Customize iTerm2 Color Scheme

Find and import themes from iTerm2 Color Schemes.

4. Add Zsh Plugins

Enhance your terminal experience with useful plugins.

a. Install zsh-autosuggestions

This plugin provides command suggestions as you type.

Install via Oh My Zsh:

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

Or install via Homebrew:

brew install zsh-autosuggestions

Add to ~/.zshrc:

plugins=(git rails ruby zsh-autosuggestions)

If installed via Homebrew, add:

source /opt/homebrew/share/zsh-autosuggestions/zsh-autosuggestions.zsh

to the bottom of ~/.zshrc.

Restart iTerm2:

exec zsh

b. Install zsh-syntax-highlighting

This plugin highlights commands to distinguish valid syntax from errors.

Install via Oh My Zsh:

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

Add to .zshrc:

plugins=(git rails ruby zsh-autosuggestions zsh-syntax-highlighting)

Restart iTerm2:

exec zsh
