Thanks for the report - is f.lux not working at all on 10.7? Or the UI is not appearing?

We are definitely trying to build for 10.7, but the oldest test machine we have is 10.8. (Also our updater, Sparkle, says it supports 10.7 too.)

We can downgrade you also, but I would love to fix what's going on.

What version are you running? There is a way to do this on all the current versions. If you are on Mac, make sure you have "Expand Daytime Settings" option checked, then set your daytime color. You will need to change the other colors.

We do not recommend sunset mode for use before bed as it still lets a lot of light through. If that's the mode most comfortable to you and you are concerned about light that can affect sleep, dimming your screen as far as you can will help a lot. See https://fluxometer.com/rainbow for some interactive charts.

@natemorales Thanks for the detailed notes, hope this gets worked out soon.

I found an INEXPENSIVE solution: use a min-DisplayPort -> DisplayPort cable. BOTH external displays are controlled by F.lux.

More details:
I discarded the USB to a DisplayLink to VGA cable, and replaced it with a mini DisplayPort to DisplayPort cable. You can find cheaper cables elsewhere. The Thunderbolt port on a Mac is a Mini DisplayPort.

If you use Recommended Settings, f.lux will not change your default system color temperature until local sunset.

I wanted to precise that it's using High Sierra, with a GeForce GT 640.

@lorna

Thanks for the information. It's great to be able to pin down the culprit at last, and to know the issue is not on your side. I'm sorry for implying it most likely was.

Do you know if 10.10.5 would indeed fix this Flux issue ? :astonished:

I get this as well - for me, it's the Flux icon itself and the Microsoft OneDrive icon. Both Flux and OneDrive have gone through updates themselves and the OS has gone from 10.13.2 to .3 to .4 while this issue has been apparent. I've also performed a Time Machine restore in that time and had to setup Flux again from scratch,

Presently, macOS 10.3.4 with Flux 39.984.

Like you, my morning workaroud is to go into Preferences > General, uncheck the Dark Theme and then uncheck again.

@herf Would it be possible to make the notification dismissable by a two-finger swipe to the right? Most notifications can be dismissed this way. For some reason, the flux one can't.

It sounds like another app is in conflict with it. Do you have Iris installed?
