There are a number of ways to use Screens to connect to another computer, depending on the operating system installed on that computer and your intended usage scenario. Stripped down to its basics, Screens is a VNC client, so it can connect to any standards-compliant VNC server (including macOS's built-in Screen Sharing feature). As long as there is a properly configured VNC server on the other end of the connection, and your network is configured to allow Screens traffic, Screens can connect.
We abstract the underpinnings for many use-cases by offering Screens Connect and Screens Express to simplify the preparation of a computer you wish to connect to, and its network. If you're unable to use either, you always have the option of configuring everything manually (see Alternative Method).
Screens Connect: When you don't have the time or inclination to configure your network for Screens, consider Screens Connect. It's the easiest way to set up a computer for remote access, and is available for macOS and Windows. See our user guides for more information.
Screens Express: If you have ever had to assist a client, a relative, or a friend with a Mac problem, Screens Express will be a revelation. Gain remote access to another Mac as a guest user with Screens Express for macOS. Screens Express is perfect for those times when you need only one-off access to a remote computer and personnel on the other end aren't comfortable with configuring network settings.
Alternative Method: It may sometimes be necessary to use an alternative configuration method to set up your computer for remote access. This may apply under conditions such as:
- You choose not to, or are unable to, install Screens Connect on the computer.
- You’re using an operating system not discussed in this guide.
- Automatic router configuration isn’t possible.
To make the computer available outside the local network, you may use a third-party dynamic DNS service such as No-IP to configure Screens with a publicly accessible URL pointing to the computer to be accessed.
