iTerm2

iTerm2 provides a macOS‑only terminal emulator that serves as a drop‑in replacement for the system Terminal app. It runs on macOS 12.4 and later, offering a modern interface and a set of enhancements aimed at users who spend extensive time in a command‑line environment. The software is distributed under the GPL v2 license and its source code is hosted on GitHub, allowing anyone to inspect, modify, or contribute to the project.

The emulator adds a variety of conveniences such as customizable profiles, split panes, and advanced search capabilities, all designed to streamline workflow without altering the core terminal experience. Documentation, a frequently asked questions page, and a community forum are available to help users configure and troubleshoot the application. Bugs and feature requests can be submitted through the project's issue tracker, and the maintainer can be contacted directly via email.

Because it is free and open source, iTerm2 is suited for developers, system administrators, and power users who need a flexible, feature‑rich terminal on macOS while retaining compatibility with existing command‑line tools.
