MacBook Desktop Mode
A holistic configuration guide for running a MacBook as an always-on-AC desktop workstation. Solves two interconnected problems: USB devices (especially USB 1.1 audio) disappearing during sleep/wake cycles, and unnecessary battery degradation from constant charge cycling.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
When to Use This Skill
- USB microphone or audio device disappears after sleep/wake
- Battery is cycling unnecessarily on a plugged-in Mac
- Setting up a MacBook as a permanent desktop workstation
- Configuring

Root Cause Diagnosis Framework
Before applying fixes, diagnose the specific failure mode. This framework was developed from empirical analysis of a MacBook Pro M3 Max with an Antlion USB Microphone (VID 0x2F96, PID 0x0200).
