For most OpenClaw setups the answer is the base Mac mini M6 with 16GB, $899 at Apple and $779 on Amazon as of Oct 23, 2026. If local models are why you're buying, start at 48GB; 24-32GB only covers small 8-14B models.

The M6 24GB has no Amazon-sold listing right now (third-party sellers ask $1,299, same as Apple's price), so that row links to apple.com instead of a `/go/` page.
## Why a Mac mini for OpenClaw (the honest answer)
There are four real reasons, and then one reason not to bother.
First, idle power. Apple's own support page lists the M6 Mac mini at 4W idle, measured at the wall ([Apple](https://support.apple.com/en-us/103253)). That is closer to a Raspberry Pi than to a desktop. An always-on agent box runs 24/7, and at the US residential average of 18.31 cents per kWh ([EIA](https://www.eia.gov/electricity/monthly/epm_table_grapher.php?t=epmt_5_6_a)), the whole year of idling costs about $6.40. More on that math below.
Second, macOS-only integrations. OpenClaw's iMessage channel needs a Mac: it works through `imsg`, a Swift CLI that reads the Messages database and sends through Messages.app automation ([docs.openclaw.ai](https://docs.openclaw.ai/channels/imessage), [github.com/openclaw/imsg](https://github.com/openclaw/imsg/)). The Apple Notes, Reminders, and Shortcuts skills are the same story. If your agent lives in iMessage threads with your family or touches your Apple account's data, no Linux box substitutes cleanly.
Third, it is silent and tiny. The Mac mini is 5 by 5 inches, 1.5 pounds, and rated at 5 dBA at idle, which is functionally inaudible ([Apple specs](https://www.apple.com/mac-mini/specs/)). It sits on a shelf next to the router and you forget it exists.
Fourth, demand says something. When the M6 mini launched, The Verge reported that last-gen Mac minis "became scarce due to higher than expected demand for running AI agents" ([The Verge](https://www.theverge.com/tech/984190/apple-mac-mini-m6-m5-pro-price-specs)). A lot of people already made this exact choice.
Now the counterpoint, because it matters: the OpenClaw gateway itself is a light Node.js process. If your agent talks to Claude, GPT, or another cloud API, the model lives on someone else's hardware and your box just passes messages. A $349 Intel N150 mini PC running Linux does that job for less than half the price, and a Raspberry Pi works too: OpenClaw's own docs call a 1GB Pi the minimum and recommend 2GB+ ([OpenClaw docs](https://docs.openclaw.ai/install/raspberry-pi)). Buy the Mac mini for the macOS features or for local models, not because the gateway needs it.
## What I run, and where 24GB runs out
My own OpenClaw box is a Mac mini M4 Pro with 24GB of unified memory, and I'll be blunt about it: 24GB is too little for local models. The gateway, the channels, and everything macOS-specific run beautifully, but once you point a real model at it the memory ceiling shows up fast. That's why I'm steering you away from calling 24GB "the local-model config" in this guide. Today's 24GB M5 Pro base config has the same ceiling, so treat the $1,599 Amazon unit as a gateway-plus-macOS machine and buy 48GB or more if local inference is the plan.
## What OpenClaw actually needs
The official requirements are short ([OpenClaw install docs](https://docs.openclaw.ai/install/)):
- Node 24.16+ or Node 26.1+, with Node 26 recommended. The installer provisions it automatically.
- macOS, Linux, or Windows.
- Enough disk for the app and your logs.
That's it. There is no CPU floor worth quoting and no RAM floor beyond what the OS needs, because the heavy lifting happens at the model provider. The memory question only appears when you point OpenClaw at a local model server: the managed llama.cpp setup uses recipes with an 8GiB host-memory floor at the small end and checks available RAM and disk before downloading ([local models docs](https://docs.openclaw.ai/gateway/local-models)).
So the decision tree is simple. Cloud models: any Mac mini works, including the cheapest. Local models: memory decides everything, which is what the next section is for. For model picks once the hardware is sorted, see the [OpenClaw + Ollama local models guide](/openclaw-ollama-local-models/) and the [best open-source models for OpenClaw](/best-opensource-models-for-openclaw/).
## How much memory for local models
On Apple silicon the GPU and CPU share unified memory, and macOS caps how much of it the GPU can pin (wire) at roughly 75% by default. On a 24GB Mac that ceiling is about 17.8GiB; a model that doesn't fit under the cap spills layers to the CPU and slows down hard. You can raise it with `sudo sysctl iogpu.wired_limit_mb=`, which takes effect immediately but is undocumented and resets on reboot ([llmconfigurator](https://llmconfigurator.com/en/guides/troubleshooting/increase-metal-vram-limit-apple-silicon), [example measurement on a 24GB M4 mini](https://mac-mini-m4-doc.masterfabric.co/)).
Treat this table as a rule of thumb, not a guarantee. Download sizes are from the [Ollama library](https://ollama.com/library), and real memory use adds the KV cache and context on top, so leave headroom.
| Unified memory | Default GPU cap | Realistic model size | Example Ollama models (download size) | Verdict |
| --- | --- | --- | --- | --- |
| 16GB | ~12GB | Up to ~8B | llama3.1:8b (4.9GB) | Cloud first; small local models fit |
| 24GB | ~17.8GiB | 8-14B | qwen3:14b (9.3GB), gpt-oss:20b (14GB) | Small models only, my own 24GB box tops out here |
| 32GB | ~24GB | Up to ~30B | qwen3:32b (20GB) | Maxes out the M6, still tight |
| 48-64GB (M5 Pro) | ~36-48GB | 30-70B | llama3.3:70b (43GB) | Where local models actually start |
| 128GB (EVO-X2 / Studio) | ~96GB | 70B-120B | gpt-oss:120b (65GB) | Local frontier-class models |
Bandwidth decides speed, not capacity. The M6 gives you 153GB/s at 16GB and 170GB/s at 24-32GB, the M5 Pro 307GB/s, and the M5 Max in a Mac Studio 460-614GB/s ([Apple tech specs](https://www.apple.com/mac-mini/specs/), [Mac Studio specs](https://support.apple.com/en-us/128107)). A 32B model on an M6 runs but generates slowly; on an M5 Pro it runs about twice as fast per token. That is what you pay for above 24GB.
## 1. Mac mini M6 16GB: best for cloud-model agents
**$779 on Amazon** (list $899) · 4.4★ from 49 ratings · #1 Best Seller in Mini Computers · sold by Amazon
Apple announced the M6 Mac mini on August 25, 2026 and it has shipped since September 22 ([Apple newsroom](https://www.apple.com/newsroom/2026/08/apple-unveils-a-more-powerful-mac-mini-featuring-the-all-new-m6-and-m5-pro/), [availability](https://www.apple.com/newsroom/2026/09/the-new-mac-mini-and-mac-studio-are-available-today/)). The base config is a 12-core CPU, 12-core GPU, 16GB of unified memory, 256GB SSD, 2.5Gb Ethernet (10GbE optional), Wi-Fi 7, and three Thunderbolt 4 ports.
The honest pitch for this box: it runs the OpenClaw gateway, the macOS app, iMessage, Notes, Reminders, and Shortcuts integrations, a browser, and whatever [dashboards](/best-openclaw-dashboards/) you watch your agents through, while idling at 4W and making no noise. If your agent uses cloud models, there is nothing here you will outgrow. The 16GB of memory even tolerates an 8B-class local model for cheap background tasks, though I wouldn't buy it planning to do that daily.
Two caveats. The 256GB SSD fills faster than you expect once models, Xcode, and Docker images land (there's a storage section below, the short answer is external NVMe). And Amazon's $779 undercuts Apple's $899 list by $120 as of Oct 23, 2026, which makes this the easy buy.
## 2. Mac mini M6 24GB or 32GB: gateway plus small models
**$1,299** (24GB/512GB) or **$1,799** (32GB/1TB), from Apple
Step up to 24GB and the M6 also bumps memory bandwidth from 153GB/s to 170GB/s. Against the memory table above, 24GB runs qwen3:14b and gpt-oss:20b after you raise the GPU wired limit, and 32GB gets a Q4 30B-class model loaded. Set expectations honestly though: this is the gateway-plus-small-models tier, not the serious local tier. If local models are the reason for the purchase, skip to 48GB.
The catch is availability. As of Oct 23, 2026, Amazon sells the 24GB/512GB config only through third-party sellers at $1,299 and stocks no 32GB config. Buy those from Apple's store instead; same $1,299 and $1,799 prices.
## 3. Mac mini M5 Pro: the local-model tier
**$1,599 on Amazon** (list $1,699) · 5★ from 4 ratings · sold by Amazon
The M5 Pro config is a different machine wearing the same shell: 15-core CPU (upgradable to 18), 16-core GPU (upgradable to 20), 307GB/s memory bandwidth, 24GB standard memory with 48GB and 64GB options, and Thunderbolt 5. Amazon sells the 24GB/512GB config at $1,599, $100 under Apple's price, but that base config shares the 24GB ceiling I complain about above. The config that matters for local models is 48GB or 64GB, both Apple-configure-to-order only: the 18-core option starts at $1,899, the 15-core 48GB/512GB build is $2,299, and a loaded 64GB/1TB runs $3,199.
Against the alternatives for local 30B-70B work:
The [Mac Studio M5 Max](/go/mac-studio-m5-max/) is $2,299 on Amazon for the 36GB/512GB config: double the memory bandwidth at 460GB/s (614GB/s on the 40-core GPU), up to 128GB unified memory, four TB5 ports. If the Mac is also your workstation, the Studio is the better buy. If it sits in a closet running agents, you paid $700 for bandwidth the gateway doesn't always need.
The [GMKtec EVO-X2 128GB](/go/gmktec-evo-x2-128gb/) is $3,649.99 on Amazon (Ryzen AI Max+ 395, 128GB/2TB, ships from Amazon): the x86 answer. Its 256GB/s of bandwidth feeds up to gpt-oss:120b at usable speed, and you get Linux, Docker, and Proxmox instead of macOS. More money than a 64GB M5 Pro, more memory, less bandwidth per dollar. I compared this class of box in the [best mini PCs for local LLMs](/best-mini-pc-local-llm/) guide.
My read: the 48GB M5 Pro at $2,299 CTO is the pick for 30B models, and the 64GB version at $3,199 is where a Mac Studio or EVO-X2 starts making more sense.
## 4. The leftover M4
The 2024 Mac mini M4 (16GB/256GB, Gigabit Ethernet) still floats around Amazon, but as of Oct 23, 2026 the main listing has no Amazon-sold buybox and third-party offers hover near $780, the same price Amazon charges for the brand-new M6. There is no world where that trade makes sense. Micro Center still lists the M4 at $799.99 (sale $679.99) and the M4 Pro 24GB/512GB at $1,599.99 (sale $1,199.99) ([Micro Center](https://www.microcenter.com/site/content/apple-mac-comparison-specs.aspx)); a $680 M4 or a $1,200 M4 Pro are legitimately good in-store deals, and everything else is leftover stock priced like it isn't leftover.
## 5. The cheaper x86 route
If your agent only calls cloud APIs, the gateway's needs are trivial: OpenClaw documents a 1GB Raspberry Pi as the minimum, recommends 2GB+, and the whole point of that guide is that the Pi works because models live in the cloud. A $349 [Beelink Mini S13](/go/beelink-mini-s13/) (Intel N150, 16GB DDR4, 500GB SSD, dual 2.5GbE, 4.5★ from 659 ratings, sold by Beelink on Amazon) gives you a real x86 box that I estimate idles around 8W at the wall, runs Linux, Docker, and Proxmox, and hosts the gateway plus a pile of containers. Compare more options in the [best mini PCs for a home server](/best-mini-pc-home-server/) roundup.
What you lose: iMessage, the Apple Notes/Reminders/Shortcuts skills, the native macOS app, and OpenClaw's Voice Wake. What you gain: normal package management, containers without a VM layer, cheaper memory, and no FileVault-vs-autologin trade-off when it reboots. If you want a local model on this class of hardware, [Ollama in Docker](/ollama-docker-install/) is the straightforward way to run it. The [Beelink SER9 Pro](/go/beelink-ser9-pro/) (Ryzen 7 H255, 24GB/1TB, ~$699) sits a tier up on paper, but 24GB of soldered memory still doesn't load the local models that make the x86 side interesting, so I would not plan around it for OpenClaw.
## Power draw and what it costs per year
The EIA puts the US residential average at 18.31 cents per kWh for July 2026, the latest published figure ([EIA Electric Power Monthly](https://www.eia.gov/electricity/monthly/epm_table_grapher.php?t=epmt_5_6_a)). The math: `watts x 24 x 365 / 1000 x $0.1831`. So a 4W box burns 35kWh a year.
| Machine | Idle watts | kWh/year | Cost/year @ $0.1831 |
| --- | --- | --- | --- |
| Mac mini M6 | 4W ([Apple](https://support.apple.com/en-us/103253)) | 35 | ~$6.40 |
| Mac mini M5 Pro | 6W ([Apple](https://support.apple.com/en-us/103253)) | 53 | ~$9.60 |
| Mac Studio M5 Max | 7W ([Apple](https://support.apple.com/en-us/102027)) | 61 | ~$11.20 |
| Beelink S13 N150 | ~8W (est.) | ~70 | ~$12.80 |
| GMKtec EVO-X2 | ~12W (est.) | ~105 | ~$19.20 |
The mini PC numbers are estimates; N150 boxes land around 6-10W at the wall and Strix Halo boxes 10-15W, by my estimate. The striking part is not that the Mac wins. It's that everything on this list costs less than a month of a mid-tier API plan to leave running all year. Idle power is a reason to prefer the Mac, not a reason it saves you real money.
## Run it headless and keep it online
A Mac mini as an always-on agent host needs four settings and one command. The steps below follow the pattern Mac-server guides like [macrun.dev](https://macrun.dev/mac-mini-server) and [hometechops](https://hometechops.com/mac/mac-mini-home-server-setup) use:
```bash
sudo pmset -a sleep 0 # never idle-sleep
sudo pmset -a displaysleep 10
sudo pmset -a autorestart 1 # boot again after power loss
sudo pmset -a womp 1 # wake for network access
```
Check it stuck with `pmset -g`. In System Settings > Energy, that maps to "Prevent automatic sleeping when the display is off", "Wake for network access", and "Start up automatically after power failure". Turn on Remote Login (SSH) and Screen Sharing under General > Sharing, and you can unplug the monitor for good.
Two real gotchas. First, automatic login is unavailable while FileVault is on, and without automatic login the Mac sits at the login window after a reboot with nothing in your user session running. The trade-off: encryption or unattended restarts. One partial fix exists if your macOS supports it: `sudo fdesetup authrestart` reboots once without stopping at the FileVault unlock screen, which covers planned restarts but not a power cut. Second, OpenClaw itself: install the gateway as a LaunchAgent so it survives reboots independent of login items ([OpenClaw install docs](https://docs.openclaw.ai/install/)):
```bash
openclaw onboard --install-daemon # or: openclaw gateway install
openclaw gateway status
```
For remote access off your LAN, the sane options are Tailscale, Headscale, or Netbird; the trade-offs are in [this comparison](/netbird-vs-headscale-vs-tailscale/). Then harden the gateway before you expose anything: auth is on by default, and the [OpenClaw security guide](/openclaw-security-guide/) covers the rest.
### The UPS question
An agent box that reboots dirty after every blip eventually corrupts something you care about. For the Mac mini plus router and modem, the right size is the [CyberPower CP850PFCLCD](/go/cyberpower-cp850pfclcd/) at $169.95: 850VA/510W of pure sine wave output, which matters because modern PSUs with active PFC can shut down on the stepped "simulated sine" cheap UPSes output. It gives you roughly 30 minutes at a ~100W load and far longer at the Mac's actual 4-15W draw. The full reasoning, including the pure-sine rule and runtime math, is in the [best UPS for home servers](/best-ups-for-home-server/) guide.
If you only want the router and modem on battery (so your WAN stays up through short cuts), the cheap option is the [APC Back-UPS BE425M](/go/apc-be425m/) at $62.50, 4.5★ from 11,415 ratings. Its output is a stepped approximation to a sine wave per APC's spec sheet, which is fine for wall-wart network gear and exactly what you should not feed a computer's PFC power supply. Keep the Mac on the CyberPower.
## Storage: 256GB fills up fast
The base M6 ships with a 256GB SSD, and model downloads eat it: llama3.1:8b is 4.9GB, qwen3:14b is 9.3GB, gpt-oss:20b is 14GB, and one 70B pull is 43GB before context. Add macOS, Xcode if you build anything, and Docker images, and 256GB is gone. Two fixes:
- Buy the [16GB/512GB config](/go/mac-mini-m6-16gb-512gb/) for $949.99 on Amazon. It is $170 over the 256GB model and the boring correct answer if you know you'll pull models.
- Bolt storage on afterward. The [UGREEN Mac mini dock and stand](/go/ugreen-revodok-mac-mini-dock/) ($54.99, 4.3★ from 146 ratings) puts an NVMe enclosure plus front ports in a stack matched to the mini's footprint; it's updated for the M6/M5 Pro chassis. For faster external SSD options, see the [TB5 NVMe enclosures](/best-tb5-nvme-enclosures/) roundup.
## What I'd buy
- **Cloud models only:** the [M6 16GB at $779](/go/mac-mini-m6/). Amazon undercuts Apple by $120 and nothing here gets outgrown.
- **Gateway plus small 8-14B models:** the [M6 24GB at $1,299 from Apple](https://www.apple.com/shop/buy-mac/mac-mini/), or the 16GB/512GB at $949.99 on Amazon if storage matters more than memory.
- **Local 30B-70B models:** the [M5 Pro configured to 48GB or 64GB from Apple](https://www.apple.com/shop/buy-mac/mac-mini/) ($2,299 for 48GB/512GB), or the [EVO-X2 128GB](/go/gmktec-evo-x2-128gb/) if you want Linux and 128GB.
- **A workstation that also runs agents:** the [Mac Studio M5 Max at $2,299](/go/mac-studio-m5-max/).
- **No macOS needed:** the [Beelink S13 N150 at $349](/go/beelink-mini-s13/), and spend the savings on the [CP850PFCLCD](/go/cyberpower-cp850pfclcd/) UPS.
If none of these fit, the [OpenClaw alternatives](/openclaw-alternatives/) roundup covers other agent stacks, and the same logic applies to most of them. Hermes users should start with the [Hermes agent setup guide](/hermes-agent-setup-guide/) and the [Hermes dashboards](/best-hermes-dashboards/) post; the hardware math above is identical for that stack.
## FAQ
The base M6 with 16GB ($899 at Apple, $779 on Amazon as of Oct 23, 2026) covers anything running cloud models. For local models I start at 48GB: my own 24GB box tops out at small 8-14B models, so 24-32GB is only a gateway-plus-light-local tier.
Three reasons: it idles at 4W and is silent, so it costs about $6 a year to leave on; OpenClaw's iMessage channel and the Apple Notes, Reminders, and Shortcuts skills only work on macOS; and it's a reliable little always-on box. If none of that matters, a $349 N150 mini PC on Linux runs the same gateway.
Node 24.16+ or 26.1+ on macOS, Linux, or Windows, per the official install docs. There's no meaningful CPU or RAM floor for the gateway itself since models run in the cloud. Local models change that: OpenClaw's managed llama.cpp recipes start at an 8GiB host-memory floor and scale with the model.
Yes for cloud-model agents, with room for an 8B-class local model occasionally. It is not enough for serious local inference, because macOS caps GPU-wired memory near 75% of RAM and the KV cache adds on top of the download size. If local models are the plan, go to 48GB or more rather than 24-32GB.
Yes, and for cloud-model setups it's the cheaper answer. An N150 box like the Beelink S13 at $349 runs Linux, Docker, and the gateway fine. You lose iMessage, the Apple ecosystem skills, and the native macOS app; you gain Linux tooling and much cheaper hardware. A Raspberry Pi works too.
The Mac Studio M5 Max makes sense when you need more than 64GB of unified memory (it goes to 128GB) or more memory bandwidth (460-614GB/s vs the M5 Pro's 307GB/s), or when the machine doubles as your workstation. For a headless box that only runs agents and a 30B-class model, an M5 Pro mini at $1,599-1,899 does the job for $700 less.
