See it and use it
Its screen, live, with your keyboard and mouse — or a finger on a phone, working like a trackpad.
Every machine you own, from anywhere.
Union shows you the screen of your Mac — and soon your PC — on another computer or in any browser, and lets you use it: keyboard, mouse, sound, clipboard and files. Straight across your own network at home, and over the internet when you’re away.
Windows is coming soon.
Your machines, as if you were in front of them
Just the window you need
Show the whole screen, one app or one window, and switch while you watch. Several machines, or several windows of one, side by side.
Hear it
The machine’s sound comes along with its picture.
Copy here, paste there
One clipboard across your machines — and the recent ones of another machine, a click away.
Files both ways
Send files, browse another machine’s folders and take what you need — or right-click a file in Finder to send it to whoever is using your Mac.
At home and away
Directly across your own network when you’re home. Over the internet when you’re not — through a relay when nothing else gets through.
Wake it up
A Mac asleep at home can be woken from another machine on the same network, or through one that is.
Yours only
Your machines find each other through your account and no one else’s. Over the internet, connections are encrypted end to end, and what you see and send goes between your machines — it is not stored on our servers.
