Part 1. What Is PuTTY?
PuTTY itself is a free, open-source terminal emulator, serial console, and network file transfer application. It supports various network protocols like SSH, Telnet, SCP, and rlogin. These features make PuTTY especially valuable for system administrators and developers working with Linux or Unix servers.
Though macOS includes a native Terminal with SSH support, many users still seek PuTTY for Mac for its GUI-based management features, saved session profiles, and consistent cross-platform interface. For those migrating from Windows to macOS or working in multi-OS environments, it provides a familiar experience that eases the transition.
There is no official PuTTY release from its original developer for macOS, but thanks to open-source communities and package managers like Homebrew, you can install a fully functional version. These versions retain all the core features, including SSH tunneling and key-based authentication. Whether you're connecting to a development server or configuring routers, PuTTY for Mac delivers the reliability and security professionals expect.
Part 2. How to Install PuTTY on Mac?
Installing PuTTY for Mac is straightforward using Homebrew, the most popular package manager for macOS. Follow these steps to get started:
Step 1: If you don't have Homebrew installed, open the Terminal and run: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Step 2: Once Homebrew is ready, install PuTTY by typing: brew install putty
- This command will install PuTTY for Mac along with related command-line tools such as pscp and plink.
Step 3: After installation, you can use PuTTY’s functions directly in the Terminal. For example: putty -ssh user@hostname
For those who prefer a graphical user interface, you can also explore third-party alternatives like iTerm2 or Termius, which serve a similar purpose to PuTTY for Mac but with more modern UI.
