Primary sources for local LLM inference on Apple Silicon: memory limits,
quantisation, KV cache behaviour, kernel panics, and benchmark methodology.

## Key measured facts

- Metal reports `recommendedMaxWorkingSetSize` = 17.76 GiB on a 24GB M4 Pro,
  about 74% of unified memory. Apple defines this as an approximation of how
  much the GPU can allocate without affecting runtime performance.
- Raising `iogpu.wired_limit_mb` made kernel panics worse, not better. Wired
  memory cannot be paged out, so raising the limit removes headroom.
- `IOGPUGroupMemory.cpp:528` panics are a GPU driver fault, not out of memory.
  The compressor was at 4% of its limit when it happened.
- Qwen3.8-27B `UD-Q3_K_XL` (12.2GB) runs at 12.60 tok/s on an M4 Pro with 16k
  context and a q4_0 KV cache. Q4_K_M (15.3GB) does not fit.
- Decode speed on Apple Silicon is memory bandwidth bound: roughly bandwidth
  divided by active weight size. 273 GB/s on an M4 Pro predicted 12.2-15.2
  tok/s and measured 12.60.
