macOS High Sierra

Use the screen curtain for privacy

Prevent people from seeing what’s on your screen by using the screen curtain, which turns the screen black.

Note: VO represents the VoiceOver modifier.

  • Press VO-Shift-F11, or triple-tap with three fingers on the trackpad.

    To turn off the screen curtain, repeat the command or gesture.

If you turn off VoiceOver while the screen curtain is on, the screen curtain is also turned off.
