Because macOS is bloody useless with external monitors, one of my monitors never obeyed night shift. I tried to resolve this with f.lux like I have on my Linux machine but it never really worked out.
Today, I discovered Nocturnal: https://github.com/joshjon/nocturnal/
Not only does this thing actually work for both monitors, but it also allows me to control the brightness for both too! Amazeballs!
