01
Agent runs
Start the run. Walk away.
Keep the Mac awake while the run is active.
FOR OVERNIGHT VIBE CODING
Your agent can work all night.
Your MacBook can stay closed.
Claude Code, Codex, and terminal agents often need hours. Lid Awake keeps macOS awake during the run. Closed-lid mode uses an approved helper so the MacBook can stay closed.
Close the lid · Keep the run alive · Pause to restore sleep
FEATURES
For the overnight part of vibe coding.
02
Overnight sessions
Wake up to progress
Keep the Mac available so Codex, Claude Code, or a terminal agent can continue.
03
Battery guard
Stop before the battery is low
Optionally set a cutoff so Lid Awake pauses before the Mac drops too low.
04
Display control
Display off, Mac still awake
Turn the display off to save battery while the Mac stays awake for the job.
05
Lock on close
Security still matters
Optionally ask macOS to lock the screen when the lid closes.
06
Guardrails
Not an always-on hack
Battery cutoff, Low Power Mode, pause timers, and one-click restore keep it reversible.
HOW IT WORKS
Made for the moment you want to close the laptop
You start an agent run, realize it needs hours, and do not want to leave the MacBook open on your desk. Lid Awake holds wake assertions; closed-lid mode also needs the approved helper.
The workflow
- Start Claude Code, Codex, or another long-running coding agent.
- Turn on Lid Awake from the menu bar and set up the helper if you need closed-lid mode.
- Close the MacBook. The display can turn off to save battery while the Mac stays awake if closed-lid mode is active.
- Pause or quit Lid Awake when you want macOS to return to normal sleep behavior.
