Computer-to-Mac — Sleep Mode | Secondary Mac

If your secondary Mac isn’t going to sleep while using Luna Display, a few macOS settings may need to be adjusted. Here's what to check:

Check your macOS sleep settings

On macOS Ventura or later:

• Go to Apple Menu > System Settings > Battery > Options…
• Turn off: "Prevent automatic sleeping on power adapter when the display is off."

On macOS Monterey 12:

• Go to Apple Menu > System Preferences > Battery > Power Adapter
• Turn off: "Prevent your Mac from sleeping automatically when the display is off."

Turn off Exclusive Fullscreen Mode

Disabling Exclusive Fullscreen Mode makes it easier to return to macOS and put your secondary Mac to sleep.

• Quit Luna Display on your primary Mac
• Open Luna Secondary on your secondary Mac
• Click the Luna Display menu (top-left corner) and choose Preferences

• Uncheck: "Exclusive Fullscreen Mode"

• Quit and reopen Luna Secondary for the change to apply
• Once Luna is open again, use Command + Tab to return to macOS and manually put your Mac to sleep

Still not sleeping?

If sleep mode still isn’t working, try quitting Luna Display on both Macs when not in use.

Extra tip: If Luna reopens automatically when your Mac boots up, you can remove it from System Settings > General > Login Items to prevent it from interfering with sleep mode.
