Show HN: 'Adrafinil' Keeps a Lid-Closed Mac Awake Only While Agents Are Working (113 pts)
GitHub / Hacker News·medium signal
A Show HN tool, Adrafinil, drew 113 points and 72 comments by solving a very specific builder pain point: keeping a lid-closed MacBook awake only for the duration that background coding agents are actually running, then letting it sleep. It's a narrow utility, but the engagement reflects how many people now run long-lived local agents and hit the macOS sleep/power-management wall. The comment thread is effectively a field guide to running overnight agent jobs on Apple hardware.
