Lid Keeper for MacBook
Close the lid.
Keep going.
Keeps your MacBook awake with the lid shut — no external display, no power adapter required. One switch, right in the notch.
Claude, Codex, vibemaxxing. They shouldn't stop because you shut the lid.
It lives in the notch. One switch. Engaged.
Temperature, uptime and fan, in view. Runs hot? It hands the Mac back to normal sleep by itself.
Why it exists
macOS puts your Mac to sleep the moment the lid closes. Lid Keeper gives you the choice.
Apple's clamshell mode works only with an external display and power connected. Lid Keeper works with neither — on a train, at a café, on the sofa — with the same conservative safety rules a careful engineer would insist on.
Features
Small app. Serious guardrails.
One switch. Then close the lid.
Flip it in the notch and shut the lid. Open it again and Lid Keeper shows you the session: how long it ran, how hot it got, how much battery it used, and whether anything tripped a limit.
Thermal guard
Watches the hottest sensor and fan speed the whole time. Under serious thermal pressure it stands down and lets macOS sleep — no app can override that.
Fans stay with Apple
Lid Keeper never sets a fan speed. macOS keeps full control of cooling, lid open or shut — exactly the behaviour Apple ships.
Battery aware
Works on battery or power. At 5% unplugged it lets the Mac sleep rather than run it flat.
Independent watchdog
A separate process holds the keep-awake lease twelve seconds at a time. If Lid Keeper ever stops, normal sleep comes back by itself.
Mic handoff
Apple disconnects the built-in mic in hardware when the lid closes. Lid Keeper hands your call to AirPods, a USB mic or your iPhone automatically, and puts it back when you reopen.
Private by design.
No account. No analytics. No background licence checks. Activating connects to lidkeeper.com once to register your Mac; after that everyday use works offline. The app is signed and notarized by Apple so macOS opens it without a fuss. Universal binary: Apple silicon and Intel, macOS 15 and later.
Setup
Ninety seconds from now, you're done.
Buy
$2.99, once. Your licence key is on screen and in your inbox the moment the payment clears.
Install
A notarized installer. You'll enter your Mac password once — keeping a Mac awake with the lid closed is a system setting, so it needs an administrator.
Flip the switch
Click the notch, turn it on, close the lid. Lid Keeper says so out loud, so you know it took.
Safety
Normal sleep is the fail-safe. Every path leads back to it.
Lid Keeper is deliberately conservative. Anything unexpected — a thermal event, low battery, a missed heartbeat, a state it can't verify — points the Mac straight back to ordinary lid sleep and Apple's own fan control.
- Install, update and uninstall all finish with closed-lid sleep verified back to normal.
- The keep-awake lease lasts twelve seconds. A separate watchdog process expires it if the main helper goes quiet.
- Serious or critical thermal pressure restores normal sleep. A closed-lid stop also asks the system to sleep directly.
- 5% battery unplugged, a 45-second missed heartbeat, or failing telemetry: the Mac sleeps.
- Fan speed is never touched. There is no manual mode, no RPM target, no curve — only Apple automatic.
- Engaging is refused unless the watchdog, lid monitor and power monitor are all ready.
Sound
It tells you when it's on.
Close the lid and Lid Keeper says so — a spoken line in the voice you choose, or a sound from the library. Turn on Shuffle and every close draws a different one.
And when you open it again,
you get the session instead of a log: duration, battery used, peak temperature, time at full fan, and a temperature/fan graph.
Versus clamshell mode
macOS can do this too. With conditions.
Apple's built-in closed-display mode is great at a desk. It just needs a desk.
