Quick Answer
🐞 Bug Alert: Can’t Connect in Computer-to-Mac Mode?
If you're unable to connect Luna Display in Computer-to-Mac mode, it might be due to a known bug where your secondary Mac switches to an incompatible connection filter.
Try this 3-step workaround:
Check the connection filter on your primary device
Reset Luna on your secondary Mac
Plug in your cable before launching Luna to make sure it's used as the main connection.
Relaunch Luna on both devices and try connecting again
Note:
This workaround may not work for everyone, but it's a great step to try if you're having trouble connecting or are getting a "Connection Attempt Failed" error message in Luna Display.
