Help

When it won't work, narrow it down step by step.

Narrow it down in the order power → discovery → firewall → pairing → input & return. For Mac, the current public support path uses the same local Wi-Fi or LAN.

Start with these two

Lost your cursor? → Press Ctrl+Alt+Backspace and the cursor returns to your own PC (center of the monitor).
Connected but input isn't working? → Re-enable OneMouse under Android Accessibility, or allow Accessibility for OneMouse on the Mac.

Troubleshooting order

Check one step at a time, in this order.

Power and permissions

Make sure OneMouse is running on Windows and on the target device. Android needs its Accessibility Service; a Mac receiving input from Windows needs Accessibility. Local Network appears on macOS 15+, while macOS 13/14 may not show it.

Same network & discovery

Check that Windows and the phone or Mac are on the same Wi-Fi or LAN. On macOS 15+, confirm OneMouse has Local Network access; on macOS 13/14, that settings item may not exist.

Firewall & isolation

If the phone can see the PC but the PC can't see the phone, it may be a Windows firewall inbound issue (whether the network is set to "Public" or "Private"). Office and café Wi-Fi can also block it with client isolation.

Pairing & connection

Confirm that pairing is finished and that the device shows as connected in Devices. For Mac, select the Mac in Windows and enter the 6-digit code displayed by the Mac. Before pairing, the input and file channels don't open.

Input & return

Push the mouse toward the arranged edge to see if it crosses over; if it doesn't, check the arrangement. If the cursor ends up somewhere odd, bring it back with Ctrl+Alt+Backspace.

Transfer

When files and clipboard won't go through.

Confirm the selected device is correct — a transfer goes to the target you selected.
Desktop-to-desktop drag requires the target Windows PC or Mac to be connected and arranged. Mac edge drag currently uses LAN.
Keep holding the file, cross the arranged screen edge, and drop it on the target to start the transfer.
If the clipboard doesn't come through, check that both apps are connected and whether a screen is off and idle.
Bluetooth is slower than Wi-Fi — send large files over Wi-Fi.

Mac · Troubleshooting

Checks for the public macOS 13+ app.

Install the public Apple Silicon build and start the LAN connection from OneMouse on Windows.

The Mac does not appear in Windows Devices.

Put both computers on the same Wi-Fi or LAN. On macOS 15+, allow OneMouse under Privacy & Security → Local Network; macOS 13/14 may not show this item. Return to OneMouse and refresh Devices in Windows.

The Mac is connected, but mouse and keyboard input do not work.

Allow OneMouse under macOS Privacy & Security → Accessibility, then return to the app so it can recheck the permission. Basic input receiving does not require Input Monitoring.

The Mac screen is blank in the Windows remote-control window.

Allow OneMouse under macOS Privacy & Security → Screen & System Audio Recording. This optional feature is LAN-only and is not provided over Bluetooth; OneMouse does not capture system audio.

Can Windows and Mac connect over Bluetooth?

Yes, as a beta: enable Bluetooth in the Mac app settings (off by default). LAN remains the officially supported path. Mac screen and window sharing is LAN-only.

Where do I start a Mac connection?

Connections are started and managed from OneMouse on Windows 10/11. Select the Mac in Windows Devices and enter the 6-digit code shown on the Mac.

Frequently asked questions

The most common problems.

It keeps disconnecting about every 10 seconds.

There are four common causes: ① client isolation on guest/office Wi-Fi, ② battery optimization cutting off the phone's background connection, ③ Windows firewall inbound blocking, and ④ Wi-Fi going into power-saving (sleep) when the screen turns off. Turn on the battery exception, allow OneMouse inbound in the firewall, and use a private Wi-Fi when possible.

The phone can see the PC, but the PC can't see the phone.

This is usually a Windows firewall inbound issue. If the current network is set to "Public", inbound may be blocked, so switch it to "Private" or allow OneMouse inbound in the firewall.

It works at home but not on office or café Wi-Fi.

Public/guest Wi-Fi often isolates device-to-device communication (client isolation) for security. In that case, devices can't find each other even on the same Wi-Fi. Use a Bluetooth connection or a personal hotspot.

It says connected, but the mouse and keyboard don't respond.

The Android Accessibility Service was most likely turned off or restarted by the system. Go to Android Settings → Accessibility and re-enable OneMouse.

The cursor is stuck on the phone, another PC, or Mac and won't come back.

Press Ctrl+Alt+Backspace to force the cursor back to the center of your own PC's monitor.

The connection drops when the screen turns off.

When the screen turns off, the phone's Wi-Fi can go into power-saving or the app can go to sleep due to battery optimization. Setting OneMouse as a battery optimization exception on Android keeps it stable. Also check the keep-screen-on option while connected.

Remote screen control over Bluetooth doesn't work well.

Mobile remote screen control moves a lot of data, so it's not recommended over Bluetooth. Use Wi-Fi for remote control. Bluetooth is well suited to mouse, keyboard, clipboard, and files.
