Night Shift & Flux not working on MacBook Air 6,2 (early 2014) since macOS 10.13.2 Hope anyone might have an idea how to troubleshoot this problem:

Since I updated my MacBook Air 6,2 (early 2014) to macOS 10.13.2 both Night Shift and Flux have completely stopped working. Meaning no matter how often I start or restart or (re-)install Flux (or change any of the settings), or no matter how often I change the Night Shift switch, I am not getting any kind of red shift whatsoever anymore.. Both used to work fine before.

I've found a lot of discussions online regarding similar problems but all seem to boil down to either:


Too old hardware, which shouldn't be the case for a 2014 MacBook Air.
Deleting ~/Library/Application Support/com.apple.backgroundtaskmanagementagent/backgrounditems.btm as discussed here.


I tried the solution mentioned by point 2 but unfortunately it didn't do anything for me. 

Does anyone know a way to pinpoint more closely what might be the cause of this problem?
Go to the 'Display' tab and check the 'Scaled' option instead of 'Default for display' (or vice-versa). Then, simply select whichever text option fits you better.

Once you select one, the display will reset automatically and you'll be having the correct display profile along with Night Shift working again.

Added the solution to Apple forums as well.
