Common Mistakes on M4 Max
- Forgetting macOS uses 6-10 GB. Treat 36 GB as 26-30 GB available, 48 GB as 38-42 GB, etc.
- Running 128K context with 27B Q8. KV cache eats 20+ GB. Cap at 64K.
- Trying to push 70B on the 36GB variant. Q4 70B needs 42 GB just for model weights — not enough headroom. Stay with Qwen 3.6 27B at Q6.
- Comparing tok/sec to a 4090 and feeling slow. M4 Max bandwidth is roughly half — that’s the trade for silent + portable + 36-128 GB unified.
