Nightfall provides a simple way to toggle macOS dark mode directly from the menu bar. Left-clicking the icon switches between light and dark modes instantly, while right-clicking opens an options menu with additional settings. (Free, open-source)
The app supports a configurable keyboard shortcut—defaulting to Control+Option+Command+T—enabling dark mode toggling from any application without reaching for the mouse. An optional animated transition feature smooths the visual change between modes, though this requires granting screen recording permissions due to how macOS handles the transition effect. The app can also be hidden from the menu bar by Command-dragging the icon away, keeping it running in the background without occupying menu bar space.
Nightfall checks for updates automatically a few times per day, notifying users via the options menu when a new version is available. Updates require manual download and installation. The app is distributed under an MIT license and can be installed via direct download from the GitHub releases page or through Homebrew Cask with brew install --cask nightfall. Resource usage is minimal, making it suitable for continuous background operation.
System requirements: macOS Catalina (10.15) or later. Version 3.1.0 is signed and notarized, eliminating the need to bypass Gatekeeper on install. App size is small (under 5 MB).
Pricing: Free and open-source under the MIT license.
Limitations: Animated transition feature requires screen recording permissions to function. Updates are not applied automatically—users must download and install new versions manually. The app offers only dark mode toggling with no additional display customization options.
Alternatives: One Switch (paid, $4.99, toggles dark mode alongside other system settings), macOS built-in keyboard shortcut via System Settings, Lungo (broader system utilities with dark mode support).
Suitable for users who want fast keyboard-driven dark mode toggling without additional overhead, particularly those who switch frequently between light and dark environments throughout the day.
