Hardware Decision

Dedicated Mac Mini vs. Daily-Driver Laptop

24/7 operation • power consumption • community consensus

Verdict

Recommendation Dedicated Mac Mini M4 ($599)
Annual electricity cost ~$13/year (15W average agent workload)
Can the laptop work? Yes, but with trade-offs
Second laptop option? Works but Mac Mini is better

1. The Community Consensus

The overwhelming recommendation from the "Claws" community (the ecosystem coined by Karpathy, Feb 2026) is a dedicated Mac Mini. The M4 Mac Mini literally went into shortage at Apple due to AI agent setups.[1]

Why Dedicated Hardware Wins

ReasonDetail
Always-on by defaultNo lid-close sleep, no "battery optimization", no interruptions. The agent's value comes from persistence — heartbeat monitoring, cron jobs, proactive reminders.
Physical security boundary"This box runs the assistant." If something goes wrong, shut it down without nuking your primary machine. Most cited reason in community discussions.
No resource contentionAgent containers competing with your work for RAM/CPU is a real annoyance, especially during builds or data processing.
Battery healthRunning a MacBook plugged in 24/7 with continuous workloads degrades battery life. Mac Mini has no battery to degrade.
Thermal designMac Mini has active cooling designed for continuous use. MacBook thermal design prioritizes portability.
Cost$599 one-time + ~$13/year electricity. No cloud bills. Pays for itself vs. any cloud compute within months.

2. Power Consumption

Mac Mini M4 Idle
3–4W

Full CPU Load
~65W
Only during local inference
Thermal throttling: The M4 (non-Pro) throttles under sustained heavy CPU load (10-15 min continuous, temps hit 105C). This is irrelevant for NanoClaw — an API-calling agent mostly idles, waits for messages, and runs occasional shell commands. Throttling only matters for local LLM inference (Ollama). The M4 Pro handles sustained loads better if you plan to run local models.[2]

3. Your Second Laptop vs. Mac Mini

You mentioned having a second laptop. Here's the comparison:

FactorSecond LaptopMac Mini M4
Always-on reliabilityMust prevent sleep (caffeinate, lid open or clamshell), risk of accidental sleep/restartDesigned for always-on, no sleep quirks
Battery degradationConstant charge degrades batteryNo battery
ThermalsFan noise, potential throttling in clamshell modeActive cooling, designed for continuous use
Form factorTakes up desk space, needs lid open or external displayCompact, headless ($5 HDMI dummy plug)
Cost$0 (already owned)$599
Remote accessTailscale + SSH worksTailscale + SSH works, plus Screen Sharing
Apple ContainerRequires macOS Tahoe (16.0+) on Apple SiliconShips with latest macOS
Pragmatic approach: Start with the second laptop now. If it works and you find value in 24/7 NanoClaw, buy the Mac Mini later. The migration is trivial — clone the NanoClaw directory, reinstall dependencies, scan the QR code. No reason to spend $599 before validating the workflow.

4. Setup for 24/7 Operation

NanoClaw's /setup skill handles service registration automatically, but here's what happens under the hood:

macOS (launchd)

NanoClaw generates a plist at ~/Library/LaunchAgents/com.nanoclaw.plist with:
