Getting started
1. Install QiuDisplay for Mac
Download QiuDisplay for Mac (free, version 1.0.0). Open the DMG, drag QiuDisplay to Applications, and open it. QiuDisplay lives in the menu bar. The iPad app works only together with the Mac app.
2. Allow permissions on the Mac
- Screen & System Audio Recording — required. When asked, turn on QiuDisplay in System Settings → Privacy & Security → Screen & System Audio Recording, then reopen QiuDisplay.
- Accessibility — optional, only needed to control the Mac by touch.
- Local Network — allow it so your iPad can find the Mac automatically.
3. Connect
- Wi-Fi: put the iPad and the Mac on the same Wi-Fi network. Open QiuDisplay on the iPad and allow Local Network access. Your Mac appears in the list.
- USB: connect the iPad to the Mac with a cable. The first time, unlock the iPad and tap Trust. QiuDisplay connects over USB automatically and prefers USB while the cable is connected.
4. Pair
Tap your Mac on the iPad, then click Allow on the Mac. The iPad becomes an extended display — you'll see it in System Settings → Displays. Next time it reconnects without asking. Two-finger tap on the iPad opens the QiuDisplay menu (Display Size, Quality, Frame Rate, Sound, Disconnect).
Requirements
- Mac with Apple silicon, macOS 15 or later
- iPad with iPadOS 15 or later (including iPad Air 2)
- The same Wi-Fi network, or a USB cable
Troubleshooting
Can't find my Mac
- Make sure QiuDisplay is running on the Mac (its icon is in the menu bar).
- Put both devices on the same Wi-Fi network. Guest networks and some office networks block devices from seeing each other.
- On the iPad: Settings → Privacy & Security → Local Network → turn on QiuDisplay. On the Mac: System Settings → Privacy & Security → Local Network → turn on QiuDisplay.
- If the macOS firewall is on, allow incoming connections for QiuDisplay (System Settings → Network → Firewall → Options).
- Connect by address: on the iPad tap Enter IP Address and type your Mac's IP address (System Settings → Wi-Fi → Details on the Mac).
- Or use a USB cable.
USB doesn't connect
- Use a cable that carries data (some charging-only cables don't).
- Unlock the iPad and tap Trust This Computer. If no prompt appears, select the iPad in the Finder sidebar on the Mac to trigger it.
- Check that the Mac sees the iPad in the Finder sidebar.
- Make sure USB Connection is turned on in QiuDisplay's settings on the Mac, and that QiuDisplay is open on the iPad.
Black screen or no picture
Turn on QiuDisplay in System Settings → Privacy & Security → Screen & System Audio Recording, then quit and reopen QiuDisplay on the Mac.
Touch doesn't work
Turn on QiuDisplay in System Settings → Privacy & Security → Accessibility. If it is already on but touch still doesn't work, use Repair Permission in QiuDisplay on the Mac. Also check that touch is enabled in the iPad's QiuDisplay settings.
No audio
- Two-finger tap on the iPad and choose where sound plays: Mac, iPad, or iPad + Mac.
- Sound capture uses the Mac's Screen & System Audio Recording permission — make sure it is on.
- Check the iPad's volume and silent mode.
Text is too small or too large
Change Display Size from the iPad menu or the Mac menu bar. macOS needs a desktop of at least about 800 × 530 points, so the largest text sizes may stop at that limit on smaller iPads; zoom inside the app you're using if you need more (for example ⌘+ in a browser).
Send diagnostics
On the iPad, open Diagnostics and tap Copy Diagnostics, then paste it into an email to us. Diagnostics stay on your device unless you send them.
