MacBook Air Display Color Temperature Changes After Logging In Since I can remember, my MacBook Air's Display has been behaving strangely. Every time I log in, the color temperature of the display changes to a warmer tone and it's very noticeable and annoying. I tried to fix it by reinstalling macOS High Sierra, but the problem is still there so the problem is at a system level, instead of my settings, maybe?

I'll inset two photos where you can see the before (bluish tone) and after (yellowish tone).

How can I prevent my display from changing to that warmer tone?

This is normal.

When macOS is booting it will access your settings and see if you have specified the color temperature. Or enabled Night Shift.

If you have enabled FileVault this change will happen after you are logged in.

I think you need to put Color Temperature on Less Warm instead of in the center. And/Or turn off the Night Shift option.
