@TheFooFighter You have the option to automatically switch to dark mode for OS X, in the f.lux preferences at sunset. Uncheck this option in f.lux.

@UNOwen The list you linked to is not of vulnerable applications, it specifically says:

this [list] has nothing to do with security. Applications are listed here just because they use Sparkle and we think they're cool.

There's a script you can run to check all your applications for vulnerability. Here's what it says about f.lux:

ok: Flux 36.6 uses HTTPS for updates - safe

Netflix can't wait ;)

And f.lux is a great App that saves me from sleep deprivation :)

Unfurtunately Netflix does the opposite 😂

But f.lux makes it less worse :)

Thanks again!

Yes this is a bug in the video driver - really the OS should load the profile when you switch users. You could do some kind of Automator to load the profile at login?

Also, if nothing else works, you could try running f.lux under her account but with all the settings set to 6500K...

Aha, perfect! Thankyou!

I tried again this morning on both an Early 2015 macbookpro and a Late 2013 macbookpro. The 2015 worked right away, the 2013 started working after a system crash (needed to force reboot after screen went dark-grey and wouldnt respond). Feel free to close this.

Which OS/ f.lux version?

@delanorochan yay, thanks for the update!

@DLackie Ha! Sorry I should do less forum support from my phone! Glad it helped.

Little up ;)

@apieringer You need to read the manual, here:

Welcome to f.lux for OS X

@Elhem-Enohpi I want to thank you, again. You really helped me adjust my monitor. Today is a cloudy day with the sky full of white clouds, and you are right. They do send a lot of light through my office window, and I need a brighter, bluer monitor rather than a dimmer, yellower or redder one. So, I tried disabling Flux, and I could see the monitor more clearly. Then I turned up the brightness a little, and this helped, too.

Thanks, again.

You might try Options > Expanded Daytime Settings

We assume people will try out the highest and lowest value, and we try to make those make sense at different times.

The published research on retinal hazards says that you need to see >1000x as much light as a really bright monitor makes to do any harm. The amounts of light seem to be too dim to matter.

Usually I say this:

One minute outdoors on a sunny day gives you as much blue light hazard as 12 hours at a computer screen.

Nobody really knows exactly what increases the risk of macular degeneration, but currently it's hard to draw a line from display exposure to retinal hazards, which is how people usually think about this.

I guess the good thing is -- f.lux still removes >90% of these frequencies by default, so there's some extra protection if it proves to be an issue.

One additional thing: if you believe you are seeing a light that puts you at some risk of retinal hazard, you'd want a filter that removes 90 or 99% of those frequencies. It makes little sense to me that people are making filters that remove 5-20% and claiming that they would help in a case like this.

Using our f.luxometer tool you can use "blue light hazard" as an action spectrum and get a visualization of the amounts:

@raj.seshadri You need to have the app, i.e. Safari, running, and in the foreground, to see the option to enable or disable f.lux for it. For example if you're in the Finder, you won't see the option for Safari. Does that help?

@GlowingApple oh well that makes sense.

Yeah, I couldn't tell you. Times like this make me wish I knew more about computers, because I am really curious why these things happen.

But anyway, thank you so much! Im glad I was able to get this resolved without having to use terminal. That always make me nervous.

@Adam-Michael-Sasine Make sure you have "automatically adjust brightness" in Display system preferences turned off. Other than that I don't know, but in an emergency you can run RedScreen for Mac OS. You have to quit f.lux first, otherwise exactly the same thing will happen! It can be a symptom of two different things trying to adjust the screen at the same time.
