for what you are telling us seems the problem is cause for flux itself and not by the MacOSX automatic brightness.

Interesting. :-/

@Elhem-Enohpi Wow, you've really got it down! I'm very impressed. I wonder just how many people do things like this, I wish more people were aware of the effects, but until then, this is still awesome!

@lvpjl look near your clock for an outline of the f.lux icon!

I have the same issue! Running OS X El Capitan on a 2013 MBP 13" retina.

Movie mode is definitely not almost the same as having f.lux disabled, or set to 6500K. I think it's basically 4000K but a little brighter overall. It's very close to the 4100-4200K setting. You have to look very hard to see any difference. If you set your Daytime and Sunset to 4100K, and Bedtime all the way up to Sunset Only, that should be close enough for "permanent movie mode".

@theejimpee It's not available yet, but if you click the search icon on the forum and search for "single display" or similar terms, it has been discussed. The team is very busy, and it may take a while, but there is probably a good chance that it will be implemented in the next version.

Thanks, guys - I'll d/l Chrome and use it for watching Netflix with f.lux, in that case.

Cheers!

I think we should look into the effects on vision with screens 2" away from our face. I just don't like the idea.

You have to turn off automatic brightness in System Preferences > Displays.

Another thing, what model apple laptop / computer are you using?

@matthewalexander we don't have an option to go that red all the time. You could try darkroom but it inverts colors so it can make your pictures look very strange.

Sometimes changing one colour will change one of the other ones too. Try to pick your Daytime colour (usually daylight), then Sunset, then Bedtime - in that order. When you're setting the Bedtime colour, be careful not to set it higher than the Sunset colour, even for a moment, because that will change the Sunset colour. It can be frustrating. Check all the colours again before you click Done. Make sure your location and wake-up time is set appropriately.

There's a lot of help in the Quickstart Guide.

Do you have a dual GPU computer? Does locking to one card or the other help? (You can use gfx.io.)

And which version of f.lux do you have, which version of Chrome do you have?
