Prepare your Windows host and Mac
The Windows PC runs your work as the host; the Mac displays and controls it. Connect both devices to the internet and install AirDesk. Choose the Windows x64 or ARM64 installer that matches the host's system type.
Open Apple menu → About This Mac to check the chip or processor. Select Apple Silicon or Intel on the download page and check the available installer and supported OS. Open the DMG, move AirDesk to Applications and launch it.
Sign in and enable sharing
Sign in to both apps with the same email account. Turn on sharing in Share My PC on Windows and check its readiness. The host should appear online in the Mac app's computer list.
To access someone else's computer, ask its owner to share access. Accepting a friend request does not automatically share a computer.
Open the remote screen and check input
Select the Windows computer in the Mac app and connect. Test clicking and typing in a simple app such as Notepad. Input and audio depend on the permissions and settings allowed by the host.
Sessions open in the installed app. The website manages accounts, computer lists and sharing. You do not need to configure Windows Remote Desktop (RDP) separately.
Connecting from Windows to a Mac instead
In the Mac app, open Share My PC → Permission troubleshooting and review Screen Recording, Accessibility and Remote Desktop. Select Open Settings for any required permission and allow AirDesk in macOS System Settings, then return to the app and select Refresh status. Restart the app if the status does not update or a restart is requested.
Screen Recording is needed to share the screen; Accessibility and Remote Desktop allow remote keyboard and mouse control. Allow Microphone and Input Monitoring when using the features that need them. Check readiness, turn sharing on and select the online Mac in the Windows app.
If the connection or screen fails
Check host power, sleep settings, app status, account and sharing permissions. Update both apps and check that the firewall allows their traffic.
The service uses a direct connection, which some company networks may restrict. Look up any displayed error code and record the time, both operating systems and app versions when contacting support.
