<![CDATA[Build 37.7 for El Capitan]]>There's a new build for El Capitan users - now the main download after a few days of testing. This build will not work on 10.6.

Most people will get an update in the next few days.

What's new:

  • Fix for a battery drain issue on some machines
  • Fix for flashing with "movie mode" on some machines
  • Updated Sparkle (automatic updater)
  • Now 10.7 minimum (and 64-bit only) due to the Sparkle update
  • Support for "big" latitudes where the sun doesn't set or rise some days
  • A "check for updates" button, by popular demand
  • Some fixes for darkroom mode

What's not fixed on all machines (because it's outside our control):

  • White spots on video with Intel video

Machine was up, I could SSH to it, but the screen was dark and flickering. Rebooted and checked the system.log. This may be a GPU failure issue, but I figured I would throw this in for those with similar errors and a LOT of Flux messages, but the more I dug the more it seemed like the issue was my GPU and not Flux.

I've now updated my NVIDIA card with their drivers, maybe it is a GPU issue and not a Flux issue. Wait and see FTW!

El Capitan, 37.7, automatic brightness enabled. It keeps flipping back to a late evening one all morning, even after I quit flux.

It didn't seem to have made a flux color profile, just standard LCD.

https://www.dropbox.com/s/nfrsc2asli2fphj/Screenshot 2016-10-09 09.56.20.png?dl=0 for my system details.

I think another contributing factor is I always have the monitor not on full brightness, normally just a couple up from the bottom. 4 blocks up from the bottom.

If I move the mouse to make the screen react, the colors will go back to the right tones, however when the time marking and stuff goes away the color goes stupid, for clear tones.
My software is up to date
All of that bluea is poorly rendered white.

(flux enabled after quitting app; turning night mode on and off randomly, etc.)

Only been using the 37.7 patch for about 10 minutes but night mode has turned on then back off once already.

Love the app even with the current problems, just wanted to provide more feedback.

Even the "Disable for an hour" doesn't work anymore. In both cases a notification is displayed, saying that it's deactivated, unfortunately it's not. Reinstalling F.lux, restarting of Mac didn't help. Furthermore, the change between active and disabled state of these versions is abrupt. Previous versions had a smooth transition in both directions, activating and inactivating F.lux, now its instantaneous.

https://justgetflux.com/mac/Flux37.6.zip

And then if you want to disable the time-based behavior:

defaults write org.herf.Flux flushSeconds 0

It's not impossible to work with but every once in a while your cursor just ends up where you didn't intend to put it.

The bug that has been breaking us on El Capitan is when the OS reports that nothing has changed, but it actually has. Will make an option to do a little less.

So it's a bit of a special case. But I remember having the same issue on my old iMac as well. An option to disable the checks would be nice, but I understand that you don't want to clutter the UI. Is it possible to check if the system has the wrong color profile and only change it when it actually does have the wrong profile?

Previously: El Capitan's automatic brightness has been restoring old f.lux profiles and not letting us know, so we made this build to try to actually make the screen come back to daytime mode. We can do a little bit less though.

Did anything get added that checks the color profile every once in a while? I'm having an issue with my video card drivers where every time the color profile is changed my cursor jumps a little. It's not so much of a problem with flux since I can just enable fast transitions. But if I don't my cursor will be jumping around the screen like crazy during a transition. But I noticed that after this update my mouse jumps a little every 10 minutes or so. Is this correct or could it be caused by another application?

So I don't need to update, but if I do there are some small fixes that would work/help EVEN on older OS X versions as well?

Sorry for the bugging. :)

Our updater isn't sophisticated enough to say "If you're on Yosemite and have a really old version, offer an upgrade, but if it's a minor change, don't say anything" but that would be nice, huh?

If not, I shouldn't be getting continual notices to update.

This shouldn't be noticeable, and it should be a lot more efficient than 36.6 was.

EDIT: Updated to 37.5

Hope this fixes everyone. Let me know.
