Can I run Qwen3 30B-A3B on Apple M4 Max (64GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated

Yes. Qwen3 30B-A3B runs on Apple M4 Max (64GB) at Q4_K_M (~20.7 GB of ~48 GB usable).

Needs ~20.7 GB Device usable ~48 GB

Runs at Q4_K_M using ~20.7 GB of ~48 GB usable. You have room for Q8_0 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M4 Max (64GB) leaves ~27.3 GB of headroom, room to step up to Q8_0 for higher quality.

FAQ

Can Apple M4 Max (64GB) run Qwen3 30B-A3B?

Yes. Qwen3 30B-A3B runs on Apple M4 Max (64GB) at Q4_K_M (~20.7 GB of ~48 GB usable).

How much memory does Qwen3 30B-A3B need?

Apple M4 Max (64GB) has room to spare. At Q4_K_M the weights are ~18.6 GB; with KV cache and runtime overhead, budget ~20.7 GB at a 4k context. It is a Mixture-of-Experts model (30.5B total / 3.3B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Qwen3 30B-A3B on macOS?

LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

Sources

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
