Terminal.app comes built into Mac. iTerm2 is a free alternative with more features. Both run the same shell (zsh) and commands work identically in both.

The difference is in the terminal app itself, not what you can do.

Quick Comparison

When to Use Terminal

Stick with Terminal if you:

• Are just learning the command line
• Occasionally use Terminal for simple tasks
• Want zero setup
• Prefer fewer options
• Use the command line casually

Terminal works fine. It's simple and reliable.

When to Use iTerm2

Consider iTerm2 if you:

• Spend hours in Terminal daily
• Want split panes (multiple terminals in one window)
• Need better search and scrollback
• Want autocomplete suggestions
• Like customizing your tools
• Do heavy development work

Key iTerm2 Features

Split Panes

Divide your window into multiple terminals:

• Cmd + D - Split vertically
• Cmd + Shift + D - Split horizontally

Work on multiple things without switching tabs.

Better Search

Cmd + F opens a search bar. Find text in scrollback history, use regex, highlight matches.

Autocomplete

Type part of a command, press Cmd + ; for autocomplete suggestions based on your history.

Hotkey Window

Set a global hotkey to show/hide iTerm2 instantly from anywhere. Like Spotlight for Terminal.

Profiles

Save different configurations (colors, fonts, startup commands) and switch between them.

Shell Integration

Optional integration that lets you:

• Click to open files
• See command status in prompt
• Better history navigation

Broadcast Input

Type in multiple panes simultaneously. Useful for managing multiple servers.

Installing iTerm2

brew install --cask iterm2

Or download from iterm2.com.

My Recommendation

Start with Terminal. It's already there and works well.

If you find yourself:

• Wishing for split panes
• Wanting better search
• Spending lots of time in the command line

Then try iTerm2. The switch is easy - same commands, same shell, just a different window.

What's the Same

Both apps:

• Run zsh by default
• Execute all the same commands
• Read your ~/.zshrc
• Support custom themes and colors
• Work with all command-line tools

Your shell skills transfer 100%.

Configuration

Terminal.app

Preferences → Profiles. Basic options for:

• Font and size
• Colors
• Window size
• Cursor style

iTerm2

Preferences → Profiles. Extensive options for:

• Everything Terminal has
• Plus: hotkeys, triggers, badges, shell integration, and much more

Performance

Both perform well. Some users report iTerm2 feels snappier with lots of output. Others notice no difference. Try both.

Alternatives

Other terminal apps for Mac:

For most people, Terminal or iTerm2 covers everything.

The Bottom Line

Terminal: Works great, zero setup, good for casual to regular use.

iTerm2: More features, worth it for power users and developers.

You can always switch later. Your commands and configurations work in both.

Keep Learning

The terminal app matters less than knowing commands. The free course teaches Terminal skills that work everywhere.
