How to share one Mac window with a phone or browser

What you need

Install the free Remote Window preview on an Apple silicon or Intel Mac running macOS 14 or later. The viewer needs a supported modern browser on a phone, tablet, or computer. They do not need a Remote Window account or app.

On the Mac, grant Screen Recording so Remote Window can capture the selected window. Grant Accessibility only if you want to allow remote control. You can share on local Wi-Fi or over the internet; the Mac and viewer may be on different networks.

Share a window in six steps

1. Open Remote Window on your Mac. Choose Internet for a viewer on another network, or Local Wi-Fi for someone on the same network.
2. Select one window. The app captures that window rather than switching to whole-screen sharing.
3. Choose a duration. Pick 1, 2, 3, 5, or 24 hours, or keep the session open until you end it.
4. Set permissions. Enable app audio or Allow Control only if you want those capabilities.
5. Create the session and send the link. Your viewer opens it in a browser or scans the QR code.
6. Approve the viewer on the Mac. One viewer joins at a time, and each new join needs your approval.

Try the interactive app preview to see this flow before installing.

What the viewer can do

After approval, the viewer sees live video of the selected window. If you enable Share App Audio, they can unmute the app's sound. That capture can include other tabs or windows belonging to the same application, so check what the app is playing before enabling audio.

If you separately allow control, the viewer can tap or click, scroll, drag, type, and use an on-screen trackpad. Keep the shared window in front while using remote control. Some keyboard shortcuts, protected input fields, or covered areas may pause or limit control.

What Remote Window does not do

Remote Window is not a full remote desktop or a Windows host app. It does not capture your entire Mac screen. The preview is locally signed but not Apple-notarized, so macOS may show a security prompt when you install it. Internet sharing depends on the connection between the devices and may use a relay when a direct connection is unavailable.

The Mac owner can end the session at any time. The invitation stops working after its chosen duration or when the host ends sharing.
