Using an Apple Watch with Luna Display

If you use your Apple Watch to unlock your Mac, it may not work while apps like Luna Display are running. Apple blocks Auto Unlock when screen sharing or similar software is active.

If you rely on unlocking your Mac with Apple Watch, we recommend disconnecting from Luna Display first.

As noted in Apple’s support article about using Apple Watch to unlock a Mac, screen sharing and similar apps can prevent Auto Unlock from working:

Luna Display uses Apple’s public APIs and requires Screen Recording permission to stream your Mac’s display to another device. Luna does not record or store your screen data. We follow Apple’s security rules and cannot change this behavior.
