AI on Mac

For Ollama, LM Studio and MLX

Macs for local AI

Choose by the model size you actually want to run: 7B, 13B, 20B or larger. Unified memory is shared, so the Mac needs enough headroom for the LLM, browser and IDE at the same time.

Short list

The core rule: do not buy by chip name. Buy by the largest local model you will use regularly. Small models are cheap. From 13B, RAM matters. From 30B, memory headroom becomes the product.

Three Mac configurations that actually make sense for local AI

Which local model is your target?

7B → Mac mini M4 with 16 GB13B–20B → Mac mini M4 Pro with 24 GBMobile + 13B–20B → MacBook Pro M4 Pro with 24 GB30B+ → Plan 48 GB or more
01

Cheapest useful Mac 16 GB RAM7B daily range

Mac Mini M4 (16 GB)

The lowest sensible entry point if you use small local models and accept that 16 GB is the lower limit.

For you if
You test small local models, work mostly in the browser and want the cheapest Mac that is still reasonable.
Why this configuration
16 GB works for smaller models and normal daily work as long as you do not keep larger models, IDE and many browser tabs active together.
Not ideal if
9B or 13B should run smoothly beside browser, IDE and other apps.

02

Best desk choice 24 GB RAM20B daily range

Mac Mini M4 Pro (24GB, 512GB)

The stronger desk buy when 13B models will run regularly and you need reserve for normal work.

For you if
You mostly work at a desk and want 13B to 20B local models without making every browser tab a memory problem.
Why this configuration
24 GB gives the LLM, browser and development tools more shared memory than the 16 GB entry Mac, while staying far below workstation pricing.
Not ideal if
30B is the real target. Then 48 GB is the cleaner choice.

03

Mobile first 24 GB RAM20B daily range

MacBook Pro M4 Pro (24 GB)

The mobile choice when local AI matters away from the desk.

For you if
You need a notebook and still want enough memory for small and medium local models.
Why this configuration
24 GB gives 13B to 20B models enough room for real use without making every browser tab the problem.
Not ideal if
The Mac almost always stays on a desk. Then the Mac mini M4 Pro is usually the clearer buy.
Why this pick

Start cheap

For 7B everyday work. 16 GB is the lower limit once macOS, a browser, editor and model share the same memory pool.

More headroom

For 13B to 20B as the everyday range. You pay for memory headroom, not for a nicer badge in the spec sheet.

Storage

Put model files on an external SSD

This will not speed up inference. It keeps Ollama, LM Studio, MLX models, datasets and backups off the internal SSD.

External SSD · 2TB NVMe · USB-C · up to 1,050 MB/s

SanDisk Extreme Portable SSD 2TB

Concrete recommendation when local models quickly fill the internal Mac SSD. The SanDisk Extreme Portable SSD 2TB is a USB-C NVMe portable SSD rated for up to 1,050 MB/s reads and 1,000 MB/s writes, with IP65 dust and water resistance.

ASIN B08HN37XC12TBUSB-CNVMeIP65

  • For large Ollama, LM Studio and MLX model folders
  • Keeps datasets and backups off the internal Mac SSD
  • Adds storage without replacing the Mac; inference still runs on CPU/GPU and unified memory
