Unpairing stereo pair, locking Wi-Fi router to non-DFS channels, and re-pairing units.

1. Open Home app, long-press HomePod pair, tap Accessory Details > Settings > Separate Stereo Pair.
2. In your Wi-Fi router admin panel, assign a fixed 5GHz channel (e.g. Channel 36 or 44) instead of Auto-DFS.

Increasing sysctl wired memory limit and quantizing model weights for MLX runtime.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

1. Increase sysctl wired unified memory limit:

   sudo sysctl iogpu.wired_mem_limit=180000

2. Load models using 4-bit or 8-bit quantization (e.g. mlx-lm.generate --model mlx-community/Llama-3-70B-4bit).
3. Flush system unified cache before heavy inference passes:

   sudo purge

Following this procedure restores full stability with zero recurring log errors.
