Connect your computers with Computer-to-Mac Mode
What is Mac-to-Mac Mode?
Luna Display's Mac-to-Mac mode allows you to use a Mac as a second display for your primary Mac.
- Luna Display currently supports the iMac as a non-retina display when using it as a secondary Mac in Mac-to-Mac mode.
- Luna Display supports the new M1 Apple Silicon chip on Mac, though there are some hardware limitations on the number of external displays allowed. Check Apple's device technical specifications to see what is compatible with your device.
Connect your Macs using Wi-Fi
If the Macs are using different networks, they will not be able to find each other. You may connect via Wi-Fi or with an Ethernet or Thunderbolt connection.
The Luna Primary app has an icon with a grey and white cat.
- For macOS Catalina or later: enable Screen Recording. Luna Display does not record or save the contents of your screen.
Open the Luna Secondary app on your Secondary Mac.
The Luna Secondary app has an icon with a black and grey cat.
Connect your Macs using Ethernet or Thunderbolt
Connect an Ethernet or Thunderbolt cable directly between your Macs. You can also connect the Ethernet cable directly to your router. You will still need to plug the Luna Display hardware into your Mac.
Using Wi-Fi Manual Connect
If the Macs do not automatically connect:
- check that both Macs are connected to the same network
- check that both Macs are connected to the same network bandwidth (5GHz or 2.4GHz)
- check that the correct apps are open on each Mac
- try Manual Wi-Fi Connect
- try connecting with Ethernet or Thunderbolt
