Hi,
This is not happening since yesterday morning - I installed Onyx and gfx.io and now it seems better. Now I think it was not used to f.lux but to other factors:

overheating leaving my computer sleeping instead of shutting it down when I'm finish...
Thanks for your help!

@ravanelli check out instructions here:

Maybe you have a "f.lux profile" if f.lux was force quit.

Again, it's a bug in macOS, and because we're not running we cannot fix it.

The fix is to reboot or to turn off automatic brightness.

For now I added this to the FAQ:

@lorna I would like to +1 the request from @Jeroen , I am experiencing the same issues. Thanks

Well, you didn't really say very much at all in your original post. Sorry. If you had explained everything like you just did, then I wouldn't have replied because then I would have known that I don't know what the answer is. Judging from your original post though (and only your original post), it sounds like normal results from f.lux doing its thing. Judging from your reply here, yes, I can see what you're saying now but you didn't say anything like this in your original post.

I could only go by what you said.

No, most screens are not bright enough to replace a light box for theraputic use.

The screenshots do show scale as uW/cm^2/nm (spectral irradiance) in the top corner, but for spiky spectra that is not the most useful number.

We might be more interested in the total irradiance for each photoreceptor, which you can find in the "non-visual" tab on our site. It shows the "equivalent illuminant E" irradiance, as well as total power.

Our models and sources are on the pages too.

Hi there,

Just wondering how to disable ''uncheck for currrent app''. Can someone help me? Can't figure it out.

Thanks in advance
