The Cheapest Mac, One Month In: a Terminal, an Agent Box, and a Number That Lied
I bought Apple's cheapest laptop as a dumb SSH terminal. It turned out to be a good box to hand an AI agent — and the benchmark I reached for to explain its limits pointed the wrong way.
- hardware
- benchmarks
- agents
My development environment lives on a desktop. Builds, Docker, anything heavy — all of it runs there. So the laptop only ever had one job:
SSH into the desktop from anywhere, and feel good to type on.
Once you accept that, the buying criteria invert. Raw CPU and GPU stop mattering. Screen, keyboard, battery, silence, weight — the terminal experience — is the whole product. The MacBook Neo (¥119,800, A18 Pro, 8GB soldered) is built for exactly that person and nobody else.
A month in, the thesis holds. Two things surprised me anyway.
It is a good box to hand an agent
This one I did not plan. When you let an AI agent run shell commands, doing it on your primary machine means the blast radius is whatever the agent decides it is. The simplest containment is not a sandbox — it is a separate physical machine you can afford to lose.
As that box, a cheap Mac beats a cheap Windows box. macOS gives you a real Unix shell out of the box, which is what agents implicitly assume; on Windows you insert WSL, and every extra layer is a new place to get stuck. Add silent operation and low idle power, and it happily lives on a shelf.
Last year, when OSS agent harnesses got popular, a lot of people bought used MacBook Airs for this. New, warrantied, and roughly the same money, the Neo mostly removes the reason to shop used.
The number that lied
FF14's launcher never opened on this machine, so I started writing that the GPU was simply too weak. Then I looked the figures up:
| Machine | FP32 |
|---|---|
| Steam Deck | 1.6 TFLOPS |
| Switch 2 (handheld) | 1.71 TFLOPS |
| MacBook Neo | ~2.1 TFLOPS (estimated) |
| Switch 2 (docked) | 3.07 TFLOPS |
It beats the Steam Deck, and the Steam Deck runs FF14 fine. Cross-architecture FLOPS is a rough guide at best, but "not enough compute" is not the explanation. The 8GB shared with the GPU — against 16GB on the Deck — is the likelier ceiling. Unverified, and still on my list.
Who it is for
If you already own the machine that does the work, this is a very good terminal and a very good box to isolate an agent in. If you want one laptop to do everything, 8GB you can never upgrade will find you fast.
And the mistake to avoid is the one I nearly published: reading a benchmark and stopping there.
