About
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: 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; a session never starts by itself.
Sessions run on AC power by default and wait if you unplug. 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 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. Any Mac with Apple silicon and macOS 26 or later. Free for 3 days with no card, then 9 USD once per Mac, tax included.
