Duo screen-fold animation
for your MacBook.

Duo is the default finish. Your desktop stays in place while progressive blur and shadow follow the lid movement, then gently settle.

SCREEN FOLD, IN MOTION

This real MacBook recording shows Duo’s progressive blur and shadow as the lid lowers and opens again.
What the demonstration shows
A MacBook displays a landscape desktop. As its lid lowers, the visible desktop stays in place while blur and shadow deepen toward the top. Opening the lid clears the effect. Screen Fold is optional and normal lid-close sleep stays the same.
A different feel. The same Mac.
Choose Duo, Plane, Silk, Shade or Frost in Settings → Screen Fold. Duo keeps content in place with progressive blur and shadow. Preview the other finishes in the app to compare how they feel.

CHECK BEFORE YOU DOWNLOAD
Made for a supported MacBook.
The Keyko app supports Intel and Apple Silicon Macs running macOS 14 or later. Screen Fold additionally needs a supported MacBook lid-angle sensor.
App compatibility alone does not guarantee live tracking. A desktop Mac has no MacBook lid. In the app, check the lid status in Settings → Screen Fold before enabling the effect.
A tested model-by-model compatibility list is not available yet. An untested model should not be assumed supported or unsupported.
A few steps. A softer close.
- Open Settings → Screen Fold in Keyko and turn it on.
- Choose Allow Screen Recording, enable Keyko in macOS System Settings, and follow Quit & Reopen if prompted.
- With your lid at its normal working position, choose Use current angle.
- Lower the lid slightly and reopen it. Adjust the finish, blur, shading and smoothness to your liking.
Press Control–Command–F to pause or resume. Normal lid-close sleep stays the same.
Follow the setup guide with screenshots →YOUR DISPLAY. YOUR MAC.
A clear view of the permission.
Live frames can contain anything visible on your built-in display. They stay in memory on your Mac to render the effect; they are not saved to disk or uploaded. System audio is not captured.
You can turn off Screen Fold or revoke its Screen Recording permission in macOS System Settings.

Duo animation questions.
What is macOS Duo animation in Keyko?
Duo is the default style of Keyko Screen Fold, an optional MacBook lid-responsive desktop effect. It changes progressive blur and shadow while keeping desktop content in place.
Is Screen Fold built into macOS?
Screen Fold is a feature of Keyko, not a built-in macOS setting.
Does it work on every MacBook?
Live tracking requires a supported MacBook lid-angle sensor and macOS 14 or later. Meeting the general app requirements does not establish that your MacBook supports live tracking. Check the lid status in Settings → Screen Fold.
Does it keep my Mac awake with the lid closed?
No. Normal lid-close sleep stays the same. Screen Fold is a visual effect, not a keep-awake feature.
Do I need to enable Screen Recording?
Yes, for the live Screen Fold effect. It is separate from Input Monitoring, which is used for keyboard sounds across apps.
Can I pause it quickly?
Yes. Press Control–Command–F to pause or resume the effect.
Are there other styles besides Duo?
Yes. Plane, Silk, Shade and Frost are also available in Settings → Screen Fold.
Can I use it with keyboard sounds?
Keyko includes both features. Keyboard sounds across Mac apps require Plus and Input Monitoring. Try the sound collection in the free online playground before choosing a plan.
