@levitation This works perfectly. As much as I appreciate the limitation for typical users, some of us want a simple feature to disable any time-based screen adjustment. Thanks! Absolutely saved me from having to look into alternatives that won't throw off my automation every morning at sunrise.

@herf Hi! I came here to add my +1 to this feature… Even though it wouldn't figure out sunset and sunrise times, I was quite happy with having added two cron jobs that pointed to two shell scripts that pointed to two Shortcuts (quite convoluted, I know) that toggled colour filters on macOS, as a bit of a workaround for this shortcoming in f.lux, only to find out about this limitation.

I would much prefer for this to be an option in f.lux as well, as a lot of people who use it and Night Shift seem to be turning to greyscale mode as well. On the iPhone and on the iPad, they mostly use Night Shift, as sideloading f.lux hasn't been an option for years, but on the Mac, having the option to use f.lux, I reckon it would be quite popular as well. As a matter of fact, with alternative app stores and sideloading on the EU, maybe f.lux could come back to iOS and iPadOS?

@generalKenobi thanks - the first one is 42.1 and the second is 42.2 - the untrusted certificate is quite unexpected but now appears to affect all builds from 2022 and before - must be some new security changes in macOS.

We've updated the website to point to 42.2, so builds going forward will have proper signatures.

@cowboyzed right now it is applied for all the displays equally. We have a per-monitor disable on Windows, which we will look at adding to macOS too.

Edit: it looks like Mac was hiding icon overflow on my top bar on smaller screens. When I connected my computer to an external monitor with a bigger screen, the icon appeared! There may be a way to fix this on the mac side (closing programs in the top bar that aren't flux should be a good start for users who don't have access to a bigger screen), but just wanted to share in case this is helpful to people!

There should be an icon in the menubar

Hi!

This is exactly what I am looking for too. Making everything monochrome red is great. But why does it inverts everything at the same time? That should be a separate thing. All my icons look odd, all shadows are wrong, photos are useless, faces cannot be recognised, basically everything looks bad. So instinctively I've tried to use MacOS built in inversion feature to "fix" it, but unfortunately macOS inverts the image after it is tinted red by f.lux, so in inversion mode it becomes cyan. (My brain froze when I switched. I didn't expect the amount of blue light into my face.)

I'd assume it could be very hard or almost impossible to make f.lux filters come after OS level filters, so it'll never play nicely with macOS built in inversion feature I think.

But that should not mean that the red filter should only be available with inverted luminance. Can we gat a mode / option to use red filter without flipping dark and light parts of the screen please?

I had the "glowing cursor" issue on a (Samsung widescreen) external monitor in Mac OS X. The solution turned out to be turning off the "High Dynamic Range" setting for the external monitor (after which the picture in general seemed better too).

work! ty

@jeffb the main thing to check is that the "correct" color profile is used for the mac monitor (it should say "Color LCD" the System Preferences > Displays > color)

Also, we did make an update a few years ago to support DCI-P3 displays (like the new Macbooks), so make sure your f.lux build is up to date also.

@Lions23 open f.lux preferences and look for the word "Location:" in that panel
