More screen. Less stuff.
Everything you need.
Nothing you don’t.
xmac.space creates a real virtual monitor on your main Mac and sends only that display to the Mac beside it.
Wireless or wired.
Connect over your local network, or use Thunderbolt when every frame matters.
Native by design.
Built in Swift with hardware video encoding for low overhead and a truly Mac-like feel.
Actually free.
No trial clock, subscription, or proprietary hardware to buy.
Up and running in minutes
Two Macs. Three steps.
No accounts or new hardware. If your Macs can see each other, you’re almost there.
Choose each Mac’s role.
Set your main Mac to Host and your spare Mac to Display.
Connect them.
Enter the Host IP over Wi-Fi, Ethernet, or Thunderbolt.
Start creating.
Arrange your new display and move your windows right over.
Simple by design
Control every detail.
Position your display, choose a resolution, pause the stream, and see live performance—all from one clean native app.
Your next monitor is already on your desk.
Give your spare Mac
a second act.
