@herf Thanks!!! I totally understand, but meanwhile could the a workaround. :)

@diogenes I don't understand... if you want to have the dark menu all time, just disable the flux one and that's it...

Yes this is in all versions. Check for the Disable menu (which is "for an hour" but you can of course toggle it back earlier).

On Windows you can use alt-end too.

Sorry there have been several requests to use a REALLY low orange in the daytime--but your post isn't this.

If you want a bit of orange glow maybe just slide the daytime slider around the 4700K mark. That may be near what you are looking for.

I meant to run at 6500K (or I actually recommend 5800K as that is direct sunlight on a white object at noon) in the daytime.

@seekingbuddha It is a one man operation--and it's also a one wonan operation! It's an awesome husband and wife team, and they are really cool people!

I fixed it.

You can do this at Terminal and relaunch after:

defaults delete org.herf.Flux SULastCheckTime

We have a button in the next version. :)

We kinda designed this for Photoshop users, who don't want a 30 second delay when they activate.

Probably we should do automatic movie triggers where more gradual changes are what you want anyway!

Found the issue - AWS is not serving files that can be installed on 10.11.1 basically. Fixing now. You should have the update soon.

Do you have a dual-GPU Macbook Pro?

We are trying to reset the system profile at exit, and it takes a few seconds to do it. So I guess the updater isn't handling a "slow exit" very well. It will probably be faster during the day.

Great, thanks for the responses guys

I just registered about a similar feature request... and found this post.

It's really not up to us.

El Cap has a new feature called Automatic Brightness that's not playing nicely with f.lux yet - under Settings > Displays you need to uncheck it for now, and if that doesn't fix you try a reboot.

It usually works well with two monitors - what's your system like? We can help you debug the flickering, just make sure you're using the latest build at www.justgetflux.com

In "Preferences" - is there any chance the daytime slider is moved to the left? (It is usually all the way to the right.)

If you use "recommended colors" in the menu (top-right) does it fix things?

36.5 has a partial fix for this, but some machines also require that you turn off "Automatically adjust brightness" in Display settings.
