Support

Most problems come down to one of a few settings. If none of these help, write to support@metahuman.network and tell us which iPhone or iPad and which Mac you’re using.

Set up

1. Install Duo Screen Host on your Mac and open it. It lives in the menu bar. Get it here.
2. Connect your iPhone or iPad and the Mac to the same Wi‑Fi network.
3. Open Duo Screen, tap your Mac, check that the 6‑digit code matches on both screens, and click Allow on the Mac.

You need macOS 26 or later on the Mac, and iOS 26 or iPadOS 26 or later on the iPhone or iPad.

Fixes

My Mac doesn’t appear in the app

• Check that Duo Screen Host is running: its icon is in the Mac’s menu bar, and its menu says your Mac “is ready on this network”.
• On the iPhone or iPad, turn on Local Network for Duo Screen in Settings › Privacy & Security › Local Network.
• On the Mac, allow incoming connections for Duo Screen Host if the firewall is on (System Settings › Network › Firewall), and allow Local Network access when macOS asks.
• Some networks, such as guest or office Wi‑Fi, keep devices apart. Use a home network, or pair by address: in Duo Screen, tap ••• › Pair by Address and enter the Mac’s IP address (System Settings › Wi‑Fi › Details) or its name, such as my-mac.local.

The app says pairing is closed on the Mac

• Your first device pairs right away. To add another, click Pair New Device in Duo Screen Host’s menu: pairing then stays open for five minutes.

The trackpad or touch doesn’t move the pointer

• Give Duo Screen Host Accessibility permission: System Settings › Privacy & Security › Accessibility. Without it you can still watch the screen.
• Check that “Allow control from devices” is on in Duo Screen Host’s menu.

The screen stays black

• Give Duo Screen Host Screen Recording permission: System Settings › Privacy & Security › Screen & System Audio Recording. Quit and reopen Duo Screen Host afterwards.

The picture is choppy or blurry

• Choose Balanced or Battery Saver in the stream’s ••• menu, under Quality. Sharp needs fast Wi‑Fi.
• Move closer to the Wi‑Fi router, or use its 5 GHz or 6 GHz network.
• Show Stats in the ••• menu shows the frame rate, bit rate and delay as you go.

Text is too small or too large in Extend

• Choose Larger Text, Default or More Space under Text Size in the ••• menu. Your Mac makes a new display at that size.

My windows moved back to the Mac

• Your Mac keeps an extended display for a minute after the device disconnects, for example when it locks. After that, macOS moves its windows to the main screen. Reconnect within the minute and they stay put.

I want to use it away from home

• Pair at home first, on the same network. Then, on the Mac, turn on Remote access in Duo Screen Host’s menu and tick Remote next to the device.
• On the iPhone or iPad, open Settings › Paired Macs, choose the Mac, and turn on Use the relay when away. The two connect directly when they can, and through our relay when they can’t, encrypted end to end either way (see the privacy policy).
• The Mac must be awake and online, with Duo Screen Host running.

I want to unpair a device

• In Duo Screen: swipe the Mac in My Macs and choose Forget, or touch and hold it and choose Forget This Mac.
• In Duo Screen Host: open Paired devices in its menu and click Remove next to the device. Remove All Devices also replaces the Mac’s keys, so every old pairing stops working, at home and away.
