I did not expect to be recommending a Mac for this. But the Mac mini with
Apple's M4 chip has turned into one of the best-value ways to run AI at home,
and the reason is the way it handles memory.

## The one thing that makes it good at this

In most computers the processor has its own memory and the graphics chip has
its own, and they copy data back and forth. Apple puts both on one shared pool
of fast memory — think a studio apartment instead of two rooms down a hallway.
AI models love this, because the model has to sit in memory that the graphics
chip can reach, and on a Mac that's just... all of it.

The practical result: a Mac mini with 32 GB can comfortably run models that
would need an $800 graphics card in a PC. And it does it while drawing about as
much power as a lightbulb.

## What it's like to live with

Silent. Genuinely — there's a fan, I've never heard it. It sits on the corner of
my desk and draws about 4 watts doing nothing, maybe 30 under a heavy model.
Over a year of running around the clock that's under ten dollars of electricity.

The software caught up in the last year. The same tools people use on a PC —
Ollama, LM Studio — run natively on the Mac now, and setup is the same twenty
minutes: install the app, download a model, start chatting.

## The catch, and it's a real one

You pick your memory when you buy it and you can **never change it**. Not "it's
hard" — it's soldered to the board. So the decision at checkout is the whole
decision.

The base Mac mini has 16 GB. For normal computing that's fine. For AI it's
tight — you'll be limited to smaller models. Moving to 24 GB is $200 more, 32 GB
is $400 more, and for this purpose that money is well spent. Buy the memory you
want for the next five years, because there's no second chance.

Storage is the other soft spot. 256 GB disappears once you've downloaded a few
models, each of which can be 5–30 GB. Apple wants a lot to give you more
internally. Don't pay it — a $100 external SSD holds your model library fine.

## Who should buy it — and who shouldn't

**Buy it if** you want the simplest, quietest, cheapest-to-run way to have your
own AI, and you're willing to spend around $800–1,000 to get a version with
enough memory. This is the one I'd hand to someone who just wants it to work.

**Buy something else if** you want to run the very largest models — a
[128 GB AMD machine](/guides/best-way-to-run-ai-at-home-2026/) will hold things
the Mac mini can't — or you're on a tight budget, where the
[Beelink SER8](/reviews/beelink-ser8/) gets you most of the way for $520.
