Keep Mac Awake for Mac

Keep Mac Awake keeps a MacBook awake with the lid closed, with no external display, keyboard or mouse, so AI coding agents, builds and downloads keep running while you are away. You start each session from the menu bar or the keepmacawake command; a session never starts by itself.

Features

• Sessions with no limit, 1 hour, 8 hours or a custom number of hours up to 168. A timed session ends on time and normal sleep returns.
• AC power by default: if you unplug, the session waits until power is back. Battery use is optional, down to a floor you pick.
• A separate watchdog restores the normal sleep setting if the app's background service or the system service stops or hangs.
• For AI agents: the keepmacawake command answers in JSON with documented exit codes, and a free plugin teaches Claude Code, Codex, Cursor and Copilot CLI to use it.
• No account, no analytics, no logs. On its own the app goes online only for updates, which install by themselves when no session runs.

The installer asks for the administrator password once, because the sleep setting is system-wide. The trial runs 3 days, with sessions up to 8 hours and no card.
