Is there a way to have total black at night?

There are several options you have to save you from covering the monitor with a pillow :)

  1. The best is to use our helper to sleep your mac. Please read our FAQ about the Helper Application
  2. You can turn the brightness down to zero. (don’t worry when the time comes, the sunrise effect will turn it back on)
  3. You can also use System Preferences / Energy Saver window to set your Display Sleep time
