Your Mac, on every screen in the room.

Share your Mac screen, grant remote control, or extend your desktop to another device—all over Wi-Fi.

macOS 15 or later · Every device runs the same app

One app, and two quite different jobs.

Local screen sharing, both ways. Any Mac can send. Any device in the room can receive — including another Mac.

Share

Show what is on your screen

Pick a display and it appears on every device that joins. Your pointer moves on their screen the moment it moves on yours.

  • Any display, chosen per person
  • Pointer replayed on your clock
  • Pinch to zoom in on their end
Extend

Or gain a screen you did not have

ExtendPilot can create a display macOS treats as real hardware, then send it to an iPad, or to the Mac already open beside you. Windows and the desktop extend onto it.

  • A real display to macOS, not a mirror
  • HiDPI, so small type survives the trip
  • Arrange it like any other monitor

Everyone can point. One person can drive.

A shared screen that nobody can touch is a video. These make it a meeting.

Point

Tap and hold to put a coloured dot on the screen, in your colour.

Draw

Sketch over the picture. Strokes travel reliably, so a line never arrives with a hole in the middle.

React

Raise a hand, agree, disagree, or say the text is too small to read.

Control

Hand someone the pointer and their taps become real clicks on your Mac. Touch your own mouse to take it back.

One finger

Move, click, drag. Hold for a right click.

Two fingers

Scroll and pinch to zoom, at the same time.

Three fingers

Mission Control, app windows, and the next space.

Your screen never leaves the room, because there is nowhere for it to go.

This is not a policy. There is no server in the middle of a session to send it to.

  • No account, ever

    There is nothing to sign in to. Open it and share.

  • Your screen stays on your Wi-Fi

    Devices find each other over the local network and talk peer to peer.

  • Your screen is never recorded

    Frames are encoded, sent, drawn, and dropped. No file is written.

  • Approved device by device

    A host approves each device once, remembered by a key in the Keychain.

Measured, not claimed

Wi-Fi is a hostile place to put a screen.

AWDL — the radio Apple devices use to talk directly — goes quiet in windows of roughly half a second, and loses packets while it is awake.

97.3%was 78.3%

Frames that reach the screen

Alternate frames ride a layer nothing references, so losing one costs exactly that frame.

2.7%was 50%

Frozen pointer frames

The pointer is replayed on the sender's clock, behind an adaptive hold.

0.8%was 23.5%

Lurching pointer frames

Interpolating between two real samples instead of easing toward one.

10was 360

Recovery requests per 107s

Asking for repairs is how a struggling link becomes a dead one, so the interval now backs off geometrically.

Why 5% loss froze 22% of frames

Video is a chain of differences, not a series of pictures. Lose one link and every frame after it decodes against something that never arrived, so the picture stops.

Questions

Does ExtendPilot need an internet connection?

No. Devices discover each other and stream directly over your local network using Apple's peer-to-peer radio. It works with the router unplugged, and on a plane.

Is this a mirror or a real second display?

Both, and you choose. Share mode mirrors a display you already have. Extend mode creates a new display that macOS treats as real hardware, so windows and the desktop genuinely move onto it.

Can someone control my Mac?

Only if you hand it to them, one person at a time, from your Mac. Moving your own mouse pauses them immediately, the grant is never remembered between sessions, and it ends the moment they disconnect.

How many devices can watch at once?

Seven. That is the peer-to-peer session's limit rather than your Wi-Fi's — eight devices including the Mac doing the sharing. Devices watching the same display share one encoder, and each person can be pointed at a different screen.

Can a Mac watch another Mac?

Yes. Every device runs the same app and either side can take either job, so a Mac can share to a Mac, extend onto a Mac, or watch one. A laptop open beside you is a second display you already own.

Is there an Android version?

Not yet—we’re working on it. An Android viewer for watching a shared Mac screen is coming soon. Sharing and extending a desktop will remain Mac features; we do not have a release date yet.

What does it cost?

Nothing while it is in beta.

What do I need to run it?

A Mac on macOS 15 or later to share. To watch: another Mac on macOS 15, or an iPhone or iPad on iOS 18. Every device runs the same app and can do either job. All on the same Wi-Fi.

What it costs

Free.While in beta

Not an introductory offer, and not a trial with a date on it.

  • No servers to pay for

    Devices talk over your own Wi-Fi, with no infrastructure in the middle charging by the gigabyte.

  • Nothing to sell

    No account, no advertising, and your screen never leaves the room.

  • Not finished yet

    Beta means rough edges, and things that change under you.

If that ever changes, it will change here first.

Put it on the screen
already in the room.

Share your Mac screen, grant remote control, or extend your desktop to another device—all over Wi-Fi.
