Set up Luna Display on a Mac

Luna Display extends your Mac’s screen to an iPad or Mac Computer, turning your Apple Device into an external display for your primary Mac. This guide will walk you through our installation process.

Primary Mac computers will use either a Thunderbolt Compatible USB-C or Mini-Display Port Luna Device.
