Nightfall
A menu bar utility for toggling dark mode in macOS, written in Swift
...Because of how this feature works, you’ll need to grant Nightfall screen recording permissions. If you’d like to hide Nightfall from your menu bar without quitting the app, you can do so by holding the Command key and dragging the icon out of the menu bar. To reveal Nightfall again, re-open the app while it’s still running. If “Check for new versions” is enabled in preferences, Nightfall will look for updates a few times per day.
