Adrafinil Keeps Mac Awake for AI Agents, Prevents Sleep

Engineers often face a challenge when running AI agents locally on their MacBooks: closing the lid forces the machine to sleep, interrupting ongoing tasks. While existing solutions like `caffeinate` or Amphetamine prevent sleep, they require manual management and can lead to battery drain if forgotten. Adrafinil offers a targeted solution by intelligently keeping a MacBook awake only when specific AI agents, such as Claude Code or Codex, are actively processing. It achieves this by installing hooks to detect agent activity and using `pmset disablesleep 1` to override lid-closed sleep behavior, even without external power or display. The application provides visual feedback in the menu bar and an audio chime upon lid closure to confirm its active status. Crucially, Adrafinil automatically re-enables sleep (`pmset disablesleep 0`) once agent activity stops or if the device begins to overheat, preventing unnecessary power consumption. It's open-source, notarized, and includes a root helper for necessary system-level control while keeping core logic unprivileged.
