Night Shift not working on Mojave solved

Hi everybody!

I have a multimonitor configuration, and once the NightShift has stopped working on one of the monitors. I read many articles and posts with a similar problem, but did not find a solution.

Alternative software solutions did not suit me, so I decided to dive deeper.

And I managed to solve my problem - it was associated with a mess in color profiles.

Here is all I did to solve the problem:

• deleted unnecessary profiles from "System Preferences->Display->Color";
• got rid of duplicated file names in folders ~/Library/ColorSync/Profiles and /Library/ColorSync/Profiles;
• assigned an unique description to each of my profiles in the ICC "desc" tag (using ColorSync Utility.app);

All these actions concerned only my own display profiles, I did not touch the "default" system profiles.

Good luck, everyone! Sorry for the bad English ...
