Two Macs. One input path.

Your cursor doesn’t stop at the edge.

OneMouse lets your pointer cross from one Mac to the other. Basic keyboard input and scrolling follow the screen you are using.

Configured desk layout

PointerKeyboardScroll

One physical setup,
two working screens.

Free. No extra hardware.

How it works

Set the desk.
Then cross it.

  1. 01

    Place the two Macs

    Choose the left, right, above, or below layout that matches your desk.

  2. 02

    Connect the route

    Give the Macs a path over your network or a direct cable.

  3. 03

    Keep moving

    Move past a configured screen edge to use the other machine.

Connection modes

Use the link
you already have.

01

Wi-Fi

For Macs on the same reachable network.

02

Ethernet

For a wired network path between your Macs.

03

Thunderbolt

For a direct cable connection between two Macs.

04

VPN

Use a directly reachable VPN address when the VPN routes between Macs and permits UDP.

Direct-cable measurement

~12 ms there and back.

In a direct-cable test, a small message reached the other Mac and came back in about 0.012 seconds.

Connection measurement only — not full input-to-display latency. Results vary by Macs, cable, and display.

Today’s release
