Turn Your Spare Mac Into a Remote Claude Code Agent: A Step-by-Step Guide

Setting up your spare Mac for Claude Code to control, a step-by-step guide

I built a dedicated spare Mac environment for Claude Code to safely handle risky research and development tasks away from my main machine. By wiping the device, creating an isolated user account, and configuring SSH with passwordless sudo, I can now control this always-on agent from my phone or primary Mac. This setup eliminates security risks while granting full access to Mac-specific apps like Unity, offering a powerful alternative to containerized solutions.

"At the end of the day, running an agent with broad permissions is safer on a machine that has nothing to lose - but you get the benefit of being able to use a full Mac instead of a container."
