OpenClaw Mac Mini Setup: Build a 24/7 AI Server

The Mac Mini M4 is the most popular hardware for running OpenClaw. Low power draw (~15W idle), Apple Silicon performance, silent operation, and macOS reliability make it the perfect always-on AI agent server. This guide walks you through turning a stock Mac Mini into a production machine.

If you haven't decided between Mac Mini and VPS yet, read our complete installation guide first.

What Mac Mini to Buy for an OpenClaw AI Agent

The Mac Mini M4 with 16GB RAM is the sweet spot. It handles a main agent plus several sub-agents without breaking a sweat.

You don't need a monitor, keyboard, or mouse after initial setup. The Mac Mini will run headless, managed entirely through Telegram and SSH.

macOS Security Hardening for Your AI Agent

Plug in a monitor and keyboard for the first 15 minutes. You won't need them again.

Create a Dedicated User Account for OpenClaw

Never run OpenClaw on your personal account. Create a separate user:

1. System Settings → Users & Groups → Add User
2. Name it something like clawagent or marc
3. Make it an Administrator (needed for installations)
4. Log into this account for all remaining steps

Enable FileVault Disk Encryption

System Settings → Privacy & Security → FileVault → Turn On. This encrypts your entire disk. If someone steals the Mac Mini, they can't read your agent's data, API keys, or memory files.

Enable the macOS Firewall

System Settings → Network → Firewall → Turn On. Block all incoming connections except the ones you explicitly allow.

How to Prevent Mac Mini Sleep for 24/7 AI Agent Operation

By default, macOS aggressively sleeps inactive machines. Your agent needs to run 24/7.

# Prevent all sleep
sudo pmset -a sleep 0 displaysleep 0 disksleep 0

# Auto-restart after power failure
sudo pmset -a autorestart 1

Verify your settings:

pmset -g

How to Install OpenClaw on Mac Mini

The fastest path is the interactive installer at installopenclawnow.com.

Or install manually:

# Install Homebrew (if not installed)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Node.js
brew install node

# Install OpenClaw
npm install -g openclaw

# Run the onboarding wizard
openclaw onboard --install-daemon

How to Connect Telegram to Your OpenClaw Agent

During onboarding, you'll set up a messaging channel. Telegram is the most popular choice.

1. Open Telegram, search for @BotFather
2. Send /newbot and follow the prompts
3. Copy the bot token
4. Paste it into the OpenClaw onboarding wizard
5. Send your first message to your bot

Your agent is now live. Message it from anywhere in the world and it responds from your Mac Mini.

How to Set Up Tailscale Remote Access for Your Mac Mini

You need a way to SSH into your Mac Mini when you're not home. Tailscale creates a secure, private network between your devices.

# Install Tailscale
brew install tailscale

# Sign in
tailscale up

Install Tailscale on your laptop/phone too. Enable SSH in System Settings → General → Sharing → Remote Login.

# SSH from anywhere
ssh clawagent@mac-mini.tail1234.ts.net

How to Configure Your OpenClaw Agent's Personality

Your agent's workspace lives in ~/.openclaw/workspace/. The key files:

Start simple. Write a basic SOUL.md and USER.md. Your agent will help you iterate from there.

Unplug the Monitor and Go Headless

You're done with physical access. Disconnect the monitor, keyboard, and mouse. Tuck the Mac Mini somewhere out of the way. It draws about 15W idle, less than a lightbulb.

Compare that to any SaaS automation tool subscription, let alone an actual employee.

Scale Your Mac Mini: From One Agent to a Full AI Team

Once your main agent is stable, you can spin up specialized sub-agents: one for social media, one for research, one for analytics, one for content. All running on the same Mac Mini, coordinated by your main agent.
