Yes — the MacBook Pro M1 Max 64GB (64 GB LPDDR5) can run Qwen3.5-27B. At Q4 with the default 8K context it needs ≈ 16.53 GB VRAM (weights 14.85 GB + KV cache 0.68 GB + 1 GB runtime overhead), which fits within 64 GB. Decode at Q4/8K: ≈ 9.4 tok/s (estimated, batch 1). FP16 (≈ 55.67 GB) also fits, at ≈ 2.6 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	16.19 GB	Yes	9.4 ± est.
Q4	8K default	16.53 GB	Yes	9.4 ± est.
Q4	32K	18.55 GB	Yes	9.4 ± est.
FP16	4K	55.34 GB	Yes	2.6 ± est.
FP16	8K default	55.67 GB	Yes	2.6 ± est.
FP16	32K	57.7 GB	Yes	2.6 ± est.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
