Hold Option.

Close the lid.

Stays awake on AC or battery.

No need to stay plugged in. It survives power transitions without dropping the session.

The screen goes fully dark.

The built-in display sleeps. Saves power, and hides your work when you walk into a room.

Wakes the instant you open it.

A clean wake every time. No relaunch, no hang, no black-screen guessing game.

Free for 7 days.

One-time. Yours forever.
Will it drain the battery or overheat? +
Your Mac runs as it normally would with the lid open. Idle work sips power; heavy work draws what it always draws. Nothing is forced to stay busy.
Does it need admin access? +
No. Clamshell runs as a normal menu bar app. It does not install a kernel extension, driver, daemon, or privileged helper, and it does not ask for sudo.
Which Macs and macOS versions? +
Apple Silicon Mac laptops on macOS 14 or later. The Option-close gesture needs a lid angle sensor: MacBook Air M2 (2022) or later, or 14-inch / 16-inch MacBook Pro (2021) or later. M1 MacBook Air, 13-inch MacBook Pro, and Macs without that sensor use the menu-bar toggle.
What if I quit Clamshell or it crashes? +
Your Mac returns to normal lid-close behavior. Nothing is left in a stuck state.
Can I get a refund? +
Yes. If it is not for you, refund details and contact are available through support.
