  • New To Mac
    I use dark mode, but there are some apps which are (IMO) just plain ugly in dark, like the calendar and mail. You could use an app like NightOwl. But there is a command for that. It's got two steps, firstly find the app's bundle id, using osascript -e 'id of app "App_Name"'. Then pass this result into: defaults write NSRequiresAquaSystemAppearance -bool Yes.

  • Mac won't switch to dark mode
    I had this issue a lot - instead of relying on the auto mode I went ahead and installed NightOwl. Now the theme changes correctly at the appropriate time. Source: about 4 years ago
  • Automatic Dark/Light Mode based on sunset/sunrise?
    Sadly, this functionality isn't built-in to Windows and (unlike macOS) there doesn't appear to be any decent third-party utilities to sort this out for you. To date, I've been using an Open-Source offering named Luna. Source: over 4 years ago
  • No "Night Shift" in preferences for my Mac Mini M1?
    For changes at exact times, use a third party util like NightOwl. Source: almost 5 years ago
  • [macOS 11.4, MBP M1] Been dark for a while outside, but the auto appearance still goes to light mode, but it works correctly on iOS.
    I just gave up with the default Mac settings downloaded NightOwl. Night Shift works as normal but NightOwl ensures that dark mode turns on at sundown. Source: about 5 years ago
