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?

I have mid 2012 MacBook Pro, and I'm using the macOS High Sierra. When I moved the sliders nothing happens. I've tried custom colours and changing settings but nothing changes the screen colour temperature.

Yes, I have a similar issue on High Sierra, I'm told a fix deleting a file (credit to user bobzippymail). I know this is an olf thread but pretty high up on google so hopefully this helps someone.

Delete "backgrounditems.btm" file under this path, and then restart your mac.

My issue is similar that it flashes on for a second and then breaks and stays off. When I reboot it starts up and works fine, but then it'll turn off, usually triggered by pressing one of the function keys like volume, brightness etc.

If anyone has a fix for this PLEASE help me, I can't really live without flux :(:(

Oh also it seems that when it randomly turns back one for a second, it's triggered by moving the mouse, but I can't turn it on by moving the mouse, it's just occasionally (every 5-10 minutes?), moving the mouse flicks it on.

What happens if you open the f.lux menu to the left of your system clock? Are you able to access it? Can you quit from there? Pics of what I mean are here: https://justgetflux.com/news/pages/macquickstart/

If you're on a dual-GPU Macbook, I made a note in a related thread about disabling our ICC profile writer, which may help:

See if this stops the crashes?
