Mac Studio M4 Max: review for local AI
Apple's desktop for local AI - caught by the 2026 shortage. We look at what matters for running LLMs locally — memory, bandwidth, speed, price — and who it is (or is not) the right buy for.
Where to buy
The button names the configuration offered. A mini PC is a complete PC alternative: check usable memory and software support. It does not replace macOS/MLX or CUDA.

macOS creators/devs targeting large models, if you can find stock.
Pros and cons
Pros:
- 546 GB/s: ~2x a DGX Spark's bandwidth
- macOS + MLX highly optimized for LLMs
- Quiet, compact, ~160 W
- Excellent MoE inference
Cons:
- 2026 shortage: 128 GB+ configs pulled, 4-5 month lead times
- Expensive
- 96 GB now caps the very largest models
- New stock scarce - check refurbished
Verdict
On paper the best Apple desktop for local AI, but the 2026 shortage pulled high-memory configs and tightened stock. To run a 70B today, a Strix Halo mini PC (128 GB) is more accessible; otherwise watch refurbished or the MacBook Pro M4 Max 128 GB.
