Tool Open source
macTilt is a native macOS application that renders a 3D clamshell-fold animation as a MacBook lid closes. It reads the lid angle sensor and uses the live display, wallpaper, or other captured desktop content as the folding surface; the image remains fixed in space while the screen hardware moves through it, progressively blurring and fading to black. When the lid is open, the overlay is hidden and click-through, with no stated CPU or GPU activity.
On Macs with a continuous lid-angle sensor, the animation follows the hinge angle directly; on machines with only a binary clamshell switch, it plays a time-based opening animation with an adjustable duration. The app uses Metal shaders, is written in Swift, supports Apple silicon and Intel Macs running macOS 14 or later, and requires Screen Recording permission to capture the desktop. It can also provide an interactive preview on desktop Macs, while external-display clamshell mode suppresses the hinge animation.

Uses a MacBook's lid-angle sensor and Metal shaders to create a live 3D folding animation when the laptop closes. The effect can use the desktop, wallpaper, or bundled artwork and remains inactive while the lid is open.
