NewErebos
Display Blackout for Mac
Inspired by Erebus, the primordial Greek deity of darkness, Erebos helps you maintain focus, enhance immersion, and protect privacy with a single click. Black out secondary monitors for movies, follow the cursor in Focus mode, or blank every display when you step away. Optional DeepVoid uses DDC/CI and Apple backlight control for hardware-level blackout on compatible displays.
