iTerm2

iTerm2 is a terminal emulator that replaces the default macOS Terminal application and serves as the successor to the original iTerm. It runs on macOS 12.4 and newer, offering a modern interface for command‑line work. The software is open source, released under GPL‑v2, and its source code is hosted on GitHub.

The program targets developers and power users who spend extensive time in a shell, providing a range of enhancements that extend beyond the capabilities of the built‑in terminal. Features include customizable profiles, split panes, and other visual and interaction improvements that aim to streamline workflow. Documentation, a FAQ, and community support channels such as a bug tracker and forum are available for troubleshooting and feedback.

iTerm2 is distributed free of charge and is considered stable for everyday use. Its open‑source nature allows users to inspect, modify, and contribute to the codebase, while the licensing ensures it remains freely redistributable.
