Same issue for me, black screen after wake up, I see the mouse pointer moving, sometimes I can get back to the desktop when pressing the power key several times, mostly I need to reboot the hard way.
MacOS Sierra 10.12.2
F.lux 37.7
MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Port)

This method works.

@herf I use a MacBook Pro (Retina, 15-inch, Mid 2014) and it doesn't have this f.lux Profile present in Displays > Color. There are a bunch of others there, however, presumably installed by default by macOS.

Interestingly, when I change to any of the Color Profiles in that list, the system does hang for a few seconds, just like when f.lux changes the color temperature.

Since I don't have a f.lux Profile in there, however, should I still try any of the suggestions in that article that you linked to?

Thanks,
John

Thanks SO much. For some reason the icon disappeared from my menubar, so I couldn't click on it to stop flux, so I could re-install. I tried for quite a while to find a solution. Yours was simple and quick. Thanks again.

Thanks for the note on "working late" - I hadn't found that before. I'm another northerner, in Minnesota, and being able to set it based on working hours, bedtime, or something like that would be very very nice.

@herf Working good so far! It would be great if f.lux could make Notification Center dark as well (a function that Apple decided to disable this in Sierra)

After following this thread, I went to Settings > Displays > Automatically adjust brightness and disabled that feature. So far so good after 15m.

@auctoris Dimming is already a feature... alt + page up.

@herf @lorna Hey! So i downloaded the app but I'm on a 13-inch 2016 MBP without touch bar. I'm getting a message that says I have only 1 GPU so it can't do its thing. The system restarts randomly only when Safari is open and f.lux is running. I looked for a pattern but there really isn't one. I've been using Chrome for the past couple of days and haven't had any issue. My uneducated guess would be that there exists some disconnect between Safari and f.lux. Any assistance would be more than welcome.

The machine specs are: MBP 2016 without Touch Bar; Mac OS Sierra 10.12.2 beta.

@yawpstang64 Oh, that would make a hell of a lot more sense with the full color smiley faces etc. Sorry about that! I hope the function is opened up to match display settings too.

Same thing here. Running on MacBook Pro with El Capitan. No icon visible in the menu bar, and when I click on the app itself in the directory, nothing happens. When I tried to open another copy, I got a notice that the first copy was running. I can't interact with it at all.
