Keeps an Apple Silicon MacBook running with the lid closed. No external display, no admin password, no Terminal. One click in the menu bar.
Closing a MacBook's lid sleeps it, stopping AI agents, downloads and remote sessions. Most lid-closed apps need an admin password or helper and turn the screen off. Clamshell needs neither and keeps the screen usable for computer-use agents.
Audience
Mac power users: developers running AI coding agents, remote Mac users.
Pricing
$9.99 for Lifetime, $19.99 for Lifetime, 3 Macs.
