Can I run Llama 4 Maverick on Apple M4 Max (128GB)?
No. Llama 4 Maverick needs ~231.7 GB even at Q4_K_M, but Apple M4 Max (128GB) only has ~96 GB usable.
Needs ~231.7 GB even at Q4_K_M, but only ~96 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 135.7 GB: Llama 4 Maverick needs roughly 231.7 GB at Q4_K_M and Apple M4 Max (128GB) leaves only about 96 GB usable for a model. No single tracked device has enough memory; Llama 4 Maverick needs a multi-GPU or high-memory rig.

FAQ
Can Apple M4 Max (128GB) run Llama 4 Maverick?
No. Llama 4 Maverick needs ~231.7 GB even at Q4_K_M, but Apple M4 Max (128GB) only has ~96 GB usable.
How much memory does Llama 4 Maverick need?
Apple M4 Max (128GB) does not have enough memory. At Q4_K_M the weights are ~226.09 GB; with KV cache and runtime overhead, budget ~231.7 GB at a 4k context. It is a Mixture-of-Experts model (400B total / 17B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Llama 4 Maverick 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.

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.
