A menu bar app for macOS

Switch to your other Mac from the keyboard.

I use two Macs with one monitor. Other Mac lets me switch the monitor input with a keyboard shortcut, so I don't have to fiddle with the buttons underneath it.

Ready when you are.

See you on the other side.

I was tired of reaching under my monitor.

Why I built it

Switching computers shouldn't mean poking at monitor buttons.

01

One shortcut

Choose a key combination once. Use it from any app whenever you want to switch.

02

Quiet by default

Other Mac lives in the menu bar and doesn't show in the Dock. You can hide the menu bar icon too.

03

Everything stays local

There's no account and nothing is sent anywhere. The app only remembers your display and shortcut settings on your Mac.

How it works

It changes the input your monitor is already using.

Most external monitors support DDC/CI, a standard that lets apps change settings such as brightness and input. Other Mac uses it to choose the input connected to your second computer.

  1. 1

    Open the app

    Other Mac finds the compatible displays connected to your Mac.

  2. 2

    Pick an input

    Choose the HDMI, DisplayPort, or USB-C port used by your other Mac.

  3. 3

    Set a shortcut

    Record a key combination. Pressing it changes the monitor input.

Keyboard and mouse

A monitor with a KVM can switch those too.

Other Mac only changes the video input. If your monitor has a built-in USB/KVM hub, set it to follow the active input and your keyboard and mouse will move with the picture. A multi-device keyboard and mouse work too.

Free and open source

This is a small app I made for my own desk.

I'm not selling it and there's no paid plan. I put the code on GitHub because other people might have the same setup, and because I like sharing the little tools I make. Use it, change it, or send a fix.
