Plenty of Mac users still need a Windows PC from time to time – for software that has no Mac equivalent, a work machine left in the office, or IT support on someone else’s computer. RealVNC Connect lets you view and control that Windows PC from your Mac, without needing to be on the same network.
Why access a Windows PC from a Mac
Typical scenarios include running Windows-only software your Mac can’t, reaching a desktop PC you’ve left at the office, or helping a colleague on Windows while you work from a Mac. Because RealVNC Connect works the same way across platforms, the setup is nearly identical no matter which OS is on each end.
What you’ll need
- A Windows PC to control, either on the same network as your Mac or reachable over the internet
- A Mac to connect from
- A RealVNC Connect account and licence – a free trial is available
- About 10 minutes to complete setup on both devices
Step 1: Set up RealVNC Server on your Windows PC
On the PC you want to control:
- Download the RealVNC Connect setup app from the RealVNC website.
- Click Download for Windows.
- Click Accept and Install.
- Once installation completes, choose Start my free trial if you’re new to RealVNC Connect, or Sign in to continue if you already have an account.
- Your browser will open automatically. Follow the on-screen prompts, then click Open to return to the RealVNC Connect Setup app.
- Review the settings shown, then click Launch. If you keep the default VNC Password, make a note of it – you’ll need it when you connect from another device.
Step 2: Install RealVNC Viewer on your Mac
On the Mac you’ll be connecting from:
- Download the RealVNC Connect setup app.
- Click Download for Mac.
- Click Accept and Install, and follow the on-screen instructions.
- Choose Start my free trial or Sign in to continue, using the same RealVNC account you used on the other device.
- Your browser will open automatically. Follow the on-screen prompts, then click Allow to return to the RealVNC Connect Setup app.
- Review the settings shown, then click Launch.
Your Windows PC will now appear automatically as a connection in RealVNC Viewer, listed under your team.
Step 3: Connect to your PC for the first time
In RealVNC Viewer, double-click the PC you want to connect to.
Verifying the connection with Identity Check
The first time you connect, RealVNC Viewer shows an Identity Check screen with a Catchphrase and Signature. Compare these against the values shown in RealVNC Server on the remote computer to confirm you’re connecting to the right machine. RealVNC Viewer remembers this identity and will warn you if it ever changes on future connections.
Authenticating
Enter the VNC Password you noted during setup. If you chose Windows Password authentication instead, use the username and password of a Windows user account.
Controlling who can connect to your PC
If you set up authentication using Windows Password, only members of the Administrators group can connect by default. To add other users, see Managing users and session permissions for RealVNC Server – otherwise they won’t be able to connect remotely, even with valid Windows credentials.
Mass deployment for teams
If your subscription includes mass deployment, IT teams can deploy, license and configure RealVNC Server across multiple Windows PCs at once using Group Policy – useful when several people need Mac-to-Windows access to a shared pool of office machines. See Deploying and licensing VNC Connect using Windows MSIs and Setting up Group Policy under Windows.
Troubleshooting common issues
- PC doesn’t appear in RealVNC Viewer: confirm both devices are signed in to the same RealVNC Connect account and team.
- Can’t authenticate: verify you’re using the VNC Password noted at setup, or valid Windows account credentials.
- Connection blocked on a corporate network: check with IT that outbound access for RealVNC Connect isn’t restricted by a corporate firewall.
Keeping your connection secure
RealVNC Connect encrypts cloud connections end-to-end, and every new connection is verified using the Identity Check described above. For extra protection, turn on two-factor authentication on your RealVNC account and use session permissions to control exactly who can view or control the PC.
