Which way should you use to access your Mac?
Start with what you need: switch-based navigation nearby, a file, or the Mac’s actual desktop. This guide walks through RemoteDuo’s Safari controller for iPhone, with iPad as a larger-screen option.
| Method | When it fits | What you need |
|---|---|---|
| Apple Switch Control | Navigate a Mac using an accessibility switch setup on the same Wi-Fi network. | Both devices on the same Wi-Fi and signed in to the same Apple Account. Enable platform switching on the Mac and Switch Control on iPhone. |
| File sync or file sharing | Read or download a document when you do not need to operate a Mac app. | The file must be available through the service you choose. Account, network and sharing conditions depend on that service. |
| Chrome Remote Desktop | View and control a prepared Mac using Google’s remote desktop service. Google also documents an iPhone browser access route. | Set up the host software on the Mac, then use the configured Google account and remote-access PIN. Follow Google’s device and network requirements. |
| RemoteDuo in Safari · beta | Use your Mac’s screen, apps and touch controls from iPhone or iPad. A native iPhone app download is not required for this route. | A supplied Mac beta, host permissions, device ID and PC connection password. Keep the Mac awake and logged in. A direct network route is required; relay fallback is unavailable. |

iPhone Mirroring goes from Mac to iPhone. Check the connection direction.
Check the essentials before you start
- Mac: the supplied RemoteDuo desktop beta on macOS 14 or later, with Screen Recording and Accessibility allowed.
- iPhone: Safari, the host’s six-digit device ID and PC connection password, plus account sign-in if prompted.
- Host readiness: awake, logged in, online and accepting incoming connections. Test the network you intend to use.
This walkthrough is for testers who already have the Mac beta. Public Mac downloads are in preparation, and the current client interface is Korean. Check beta availability and setup.
Prepare the Mac before you leave
Run the supplied RemoteDuo desktop beta on the Mac you want to reach. This can be a MacBook, iMac or Mac mini running macOS 14 or later. Allow Screen Recording and Accessibility, enable incoming connections, and leave it awake, online and logged in. A development build must already have been supplied to you; public download is still being prepared.
Your iPhone is the controller. It does not wake a sleeping Mac, unlock FileVault, or control the macOS login screen in this beta. Check host permissions.
Open Safari and connect to the host
Open the mobile controller in Safari on your iPhone. Follow the sign-in prompt if one appears, then enter the host Mac’s six-digit device ID and PC connection password. The account password and PC connection password are separate. Opening the controller page alone does not begin a remote session.
Open mobile controllerThe current client interface is Korean. The public App Store release and a native iPhone download are not offered on this website. Safari browser access is the route described here.
Use trackpad gestures on a small screen
Slide one finger to move the remote pointer, then tap to click at the pointer’s current position. This behaves like a trackpad; tapping an arbitrary location does not directly place the cursor there. Use the right-click button or enable drag mode when needed.
Move two fingers together to scroll. Pinch to zoom, and move three fingers to pan a zoomed view. The zoom percentage button returns the screen to fit. Try landscape orientation when a wide Mac window is difficult to read; the Mac’s app layout itself is not automatically redesigned for the phone.
Type and use the shortcut toolbar
Tap the bottom text field to open the keyboard. Use the on-screen shortcut menu for commands such as Command-Tab, copy, paste, Escape and arrow keys. For composed text, finish the character composition before expecting it to appear on the Mac. Browser tools differ from the desktop app; desktop PNG clipboard sharing is not an iPhone browser feature.
Keep the controller visible and test the network
You can add the controller to your Home Screen from Safari’s Share menu. It still needs the network and a prepared host Mac. Keep it visible during a session: locking the phone or switching apps can cause Safari to suspend the connection. Return and follow the reconnect prompt if the session stops.
Test Wi-Fi and the cellular connection you intend to use before depending on it. Carrier NAT, guest Wi-Fi and company firewalls may block a direct route. RemoteDuo has no relay fallback. A local-network success does not prove cellular reachability. Connection troubleshooting.
This is the reverse of iPhone Mirroring
Apple iPhone Mirroring lets you use an iPhone from a Mac. This guide describes the other direction: using an iPhone to see and control a Mac. It is also more than using the phone as a local mouse, because the controller displays the Mac’s screen.

iPhone to Mac not connecting? Start with the symptom.
Find the closest symptom, make one check, then try the same connection again. Screen capture, input permission and network reachability are different stages.
| What you see | Check first | Next step |
|---|---|---|
| Mac is offline | Is the Mac awake, logged in and online? Is RemoteDuo running with incoming access enabled? | Check the host Mac first. Retry from iPhone after the host is ready. Remote wake and pre-login control are outside this beta. |
| ID or password is rejected | The account password and the host’s PC connection password are different. Check the host’s six-digit device ID. | Review credentials and any lockout message. Follow the displayed message before trying again. |
| Connected, but screen is blank | Start with Screen Recording permission on the host Mac. A connected session does not prove that capture is available. | Open the Screen Recording steps. If macOS requests an app restart, do this when it is safe to end the active session. |
| Screen visible, but no click or typing | Check Accessibility and whether the session has control access. On iPhone, move the pointer by sliding before tapping. | Review input permissions. Check trackpad gestures. |
| Wi-Fi works; cellular fails, or connection times out | Host readiness and direct-route restrictions are separate checks. Carrier NAT, guest isolation or firewalls may prevent a route; a timeout alone does not identify which one. | Understand direct connection limits. Compare the same devices on the intended networks. Reconnecting requires an available direct route. |
| Stops after phone lock or app switching | Safari may suspend a background session. Return to the controller, keep it visible and check that the Mac is still ready. | Follow the on-screen reconnect message. If the session has ended, connect again with the host credentials. |
Finish a small task, then end the session
For a first session, try a small change in a document you can safely edit, then check the result on your Mac’s screen.
- Move the pointer, open the document and zoom until the text is readable.
- Use the text field to enter a short phrase, finish any text composition, then save in the Mac app. Check the saved result on screen.
- Tap “종료” (End) in the controller to disconnect. This ends the remote session and does not shut down the Mac.
For a longer document or several Mac windows, continue on iPad for more room. Set up iPad access.
