I want to keep it turned on until I turn it off, not until some fixed date. How to achieve this?

(I know about the option to use f.lux, but I'd prefer to not depend on it now that macOS is so close to being able to do it itself)

In the preferences (System Preferences > Display > Night Shift) do the following:

  • set 'Schedule' to Custom
  • set 'From:' to 00:00
  • set 'to:' to 23:59
  • adjust the Color Temperature as desired

Now night shift will be enabled all the time. Disable it using the Notification Center or using the 'Manual' toggle in the preferences pane.

    doesn't work. apparently it decides that the "night" part is the 1-minute interval. Commented May 28, 2017 at 6:13
  • In this case please try it with two other times like 'from 10:00 to 09:59'. This will activate it for 24:00 hours. The larger time value (10:00) should be in the left. Otherwise it will be activated for just two minutes. :)

  • hmm, maybe it doesn't apply the schedule setting immediately and I have to wait 1-2 days Commented May 28, 2017 at 7:13
  • Is there a solution for that? How to make custom Night Shift settings remain stick forever indefinitely on Mac Sierra?

    For the latest version of Catalina, if I don't tick "Turn On Until Tomorrow" (BTW, the word 'on' should not be uppercased, Apple), it doesn't work. If I do tick it, the next day it's gone. So, this is still a fail. Commented Feb 28, 2020 at 18:06

open Notification Center, swipe down and manualy change.

  • That doesn't keep it on forever...
