f.lux overview

f.lux makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen? During the day, computer screens look good - they're designed to look like the sun. But, at 9 p.m., 10 p.m., or 3 a.m., you probably shouldn't be looking at the sun. It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.

What’s new in version 42.2

  • Fixes for "fullscreen disable" on Ventura
  • Fixes for "dim on disable" on Monterey and other OSes
  • Native support for Apple Silicon
  • Support for DCI-P3 wide-gamut displays. Previously, they looked a bit greenish and oversaturated, but now they look better than standard gamut displays.
  • Darkroom fix on M1/Apple Silicon

Will this work on an M1 Macbook Air when connected to a single monitor?

It's kinda frustrating because Mac has almost the same built-in feature (I can't remember exactly...something from sunset to sunshine) Maybe it still useful with older Macs

It helps at night, but every morning it switches the appearance on Mac back to "light mode" when I always have it on dark mode. Super annoying.
