PuTTY Alternatives for macOS: The Top Tools for Secure SSH

Regarding secure remote server access, PuTTY has long been the go-to tool for Windows users. 

However, for Mac users, PuTTY isn’t always the best fit—or even necessary, given that macOS comes with built-in terminal support. Still, many professionals seek advanced alternatives that offer more features, better interfaces, and enhanced security for SSH connections.

In this blog, we’ll explore the top PuTTy alternatives for Mac, focusing on modern, secure, and user-friendly options. 

Attune

Termius

Another excellent PuTTY alternative for Mac is Termius — a modern SSH client with a polished, intuitive interface.

Termius turns SSH from a basic command-line tool into a complete command centre for remote systems management. It offers:
