Your PC, like a second screen of your Mac

No second keyboard on the desk, no reaching for another mouse.

Move the pointer straight onto your PC

Push the pointer off the edge of your Mac’s screen, on the side where your PC sits, and it carries on onto the PC. Your keyboard and trackpad follow. Come back the same way.

Copy on one, paste on the other

Copy text on your Mac with ⌘C, paste it on the PC with Ctrl+V, and back again. Whatever you last copied is ready on whichever computer you’re using.

Hear your PC through your Mac

The PC’s sound plays on your Mac’s speakers or headphones while you’re connected, and the PC goes quiet. Disconnect and its speakers come back as they were.

Paired and encrypted

Pair once like Bluetooth: both screens show the same 6-digit code. Everything is encrypted, and your PC only accepts Macs you approved on it.

Set up in two minutes

A setup guide walks you through it: one macOS permission, the free PC app, pairing, and which side your PC is on. No config files, no IP addresses.

Windows and Linux

Windows 10 (2020 or later) and Windows 11, and Linux with the GNOME desktop such as Ubuntu. Pair as many PCs as you like and switch between them from the menu bar.

Install

CommandDesk on your Mac, and the free PC app on your Windows or Linux PC.

Pair

Your PC appears in CommandDesk. Click Pair, check both screens show the same code, click Allow on the PC.

Point

Tell CommandDesk which side your PC sits on, then move the pointer off that edge of your screen.

Questions

What do I need on the PC?

The free CommandDesk PC app, from smartinggoods.com/commanddesk/pc: Windows 10 (version 2004 from 2020, or later) or Windows 11, or Linux with the GNOME desktop (Ubuntu 24.04 or later, for example). Other Linux desktops such as KDE or Cinnamon aren’t supported yet.

Which Macs work?

Any Mac with macOS 13 Ventura or later, Apple silicon or Intel.

Do the Mac and PC need a cable?

No. They just need to be on the same network, Wi-Fi or wired. A wired PC feels snappiest; on a busy public Wi-Fi the pointer can lag at times, as with any tool like this.

Is it safe on a shared network?

Yes. You pair each PC once by checking that both screens show the same 6-digit code. After that the connection is encrypted, your Mac only talks to the PC it paired with, and the PC refuses any Mac you didn’t approve.

How does the sound work?

While your Mac is connected, the PC’s sound plays through your Mac and the PC’s own speakers are muted. When you disconnect, they come back exactly as they were. On Windows versions before 2020 the PC keeps playing too.

Can I control two PCs at the same time?

One at a time. Pair as many as you like and switch between them from the CommandDesk menu.

Is it a subscription?

No. $19 once for your Mac, including updates. The PC app is free.

What is the refund policy?

If CommandDesk can’t connect to your PC, refund it yourself within 14 days from Manage my order (link below and in your licence email). It’s immediate.
