iTerm2 is a free, open-source terminal emulator designed specifically for macOS. It replaces the default Terminal app with advanced features that developers and power users need. This iTerm2 review covers everything from split panes to AI chat features. Whether you're managing servers, writing code, or running scripts, iTerm2 offers tools that make terminal work faster and easier. The app has been around since 2009 and continues to receive regular updates. It's become the go-to terminal for Mac users who spend significant time in the command line. iTerm2 requires macOS 10.14 or later and runs on both Intel and Apple Silicon Macs.
Key Features
Split Panes: Divide your terminal window into multiple panes horizontally or vertically. Work in different directories simultaneously without switching between windows. Each pane operates independently with its own session.
Hotkey Window: Set up a system-wide hotkey to show or hide iTerm2 instantly. The terminal slides down from the top of your screen like a dropdown console. Access your command line from any app without disrupting your workflow.
AI Chat: Recent versions include built-in AI assistance to help with commands and troubleshooting. Ask questions about terminal commands or get suggestions directly in iTerm2. This feature launched in 2025 and makes learning command-line tools easier.
Autocomplete and Paste History: iTerm2 remembers your command history and offers suggestions. Command suggestions are available via a shortcut based on your window history, without requiring complex setup. The paste history feature lets you access previously copied text. Search through old commands quickly with the built-in search function.
Profiles and Custom Themes: Create multiple profiles with different color schemes, fonts, and keyboard shortcuts. Switch between profiles for different projects or environments. Import community-created themes to customize your terminal's appearance.
Advanced Search: Search through your terminal output with regular expressions and highlighting. Find specific log entries or command results instantly. The search function works across all your scrollback buffer.
Tmux Integration: iTerm2 integrates with tmux so that native iTerm2 windows and tabs replace tmux's text-based interface, letting you manage tmux sessions more visually. Control tmux sessions through native iTerm2 features instead of keyboard commands.
User Experience
iTerm2 feels native to macOS with smooth animations and standard Mac keyboard shortcuts. The interface is clean and doesn't get in the way of your work. New users can start with default settings and gradually discover advanced features. The split pane system works intuitively with drag-and-drop resizing. The hotkey window feature becomes indispensable once you start using it regularly.
