Mac Duo updates

Version 1.3

27 September 2026 · Build 443

The biggest update yet.

Mac Duo 1.3 is here. We rebuilt the experience around a smoother, cleaner fold.

A cleaner start

The fold now starts cleanly after a capture session ends, without briefly showing the previous animation frame.

A cleaner sleep

Mac Duo now stops screen capture when your Mac sleeps and stays stopped while the lock screen is visible.

A smoother experience

Further improvements make folds and transitions feel cleaner and more polished.

External displays

With an external display connected, closing your MacBook lid now leaves that display completely alone. The fold stays on the built-in screen, where it belongs.

A cleaner reopen

Reopening your MacBook lid now returns to your desktop cleanly, instead of briefly showing the fold again.

Reset animation when paused

A new option in the menu bar and in Feel settings. Pause the lid part-way and the animation smoothly returns to normal, then starts fresh when you carry on closing.

A steadier hold

Holding your MacBook lid still part-way now keeps the animation perfectly still, at any angle.

Onboarding comes first

New users now start with a short welcome to Mac Duo, instead of notes from earlier updates.

Easier to catch up

Missed a few updates? What's New now shows the most recent changes in a compact window that scrolls when there's more to read.

Clearer onboarding

The welcome screens now read more clearly in both Light and Dark Mode.

A smoother restart

Fixed an issue that could cause Mac Duo to freeze while restarting after you allowed Screen Recording.

Version 1.2

A more native Mac Duo

Mac Duo now feels more at home on your Mac, with a more consistent interface, a calmer preview and an experience that adapts to the macOS you're running.

One interface

Every window now shares the same surfaces, spacing and buttons, so Mac Duo feels like one app wherever you are in it.

Suited to your macOS

The interface takes on the look of whichever macOS you are running, with a refined finish on newer systems and a properly native one on earlier releases.

Light and Dark

Mac Duo follows your Mac's appearance and reads clearly in both.

A calmer preview

The Settings preview plays through once when you open it, then waits. Scrub it by hand, press Play to loop it, or Pause to hold a frame. It also stops rendering when you're not using it.

A cleaner exit

Mac Duo now properly finishes an in-progress screen capture when you quit, preventing the system from incorrectly showing Mac Duo as still sharing.

A smoother fold

The fold now fades in from the moment it becomes visible, making fast lid movements feel smoother.

A smoother interface

Mac Duo's interface now stays visible while the fold animation is running, instead of disappearing until the animation finishes.

Version 1.1

14 September 2026

More control over your fold

Finer control over when the fold responds, what it does while the lid is still, and how clearly Mac Duo tells you what it found on your Mac.

Minimum movement

Set how far the lid has to move before the fold responds, so small adjustments while you work are less likely to trigger it.

Resting angle

Recalibrate your resting angle and Mac Duo remembers it, including between launches.

Stationary frame rate

Choose 15, 30, 60, 90 or 120 FPS for when the lid is still. Moving the lid returns the fold to full rate, and a lower stationary rate can reduce battery use.

Sensor detection

Mac Duo is better at finding the lid-angle sensor. Some Macs do not expose the continuous sensor the fold needs, and Mac Duo now explains that clearly when it cannot find one.

Settings preview

The Settings preview now stops when the Settings window is closed, reducing unnecessary background work.

Update checks

Mac Duo checks macduo.co.uk for a newer version. It is the app's only network connection, and you can turn it off from the menu bar.
