night shift not working on Mojave

Hi guys,

I just upgraded from Sierra to Mojave and now, Night Shift isn't working anymore on my MBP early 2013.

I tried several workarounds enabling location services for the setting of the zone, switching displays, unchecking and checking the boxes in the privacy settings, I also tried the "custom" and "sunrise to sunset" setting, nothing seems to work.

Weirdly, Night Shift works perfectly on my external monitor but not on the MBP itself when its disconnected from the external display (I tried a reboot as well).

Did I miss something here?

Cheers and thanks for your feedback,

Alexander

MacBook Pro with Retina display, macOS Mojave (10.14)

Thanks pedro d,

Yesterday I called Apple Technical Support and we tried your steps as well (none of them worked, not even Safe Mode or the new admin user account). Appears to be a bug of Mojave or this particular install (this build still has some performance issues, e.g. startup takes forever). I'll wait a couple of days, hopefully technical support gets back to me. Otherwise I'll reinstall Mojave and see then what happens.

Best.

Unfortunately, Night Shift still does not work after Mojave update (10.14.1) and neither do the the isolating steps (I should have stuck to HS). I guess I have to reinstall the Mojave from the scratch. This is very annoying stuff Apple!

Hi again, I just re-installed the OS from the scratch (erased everything and recovered from Time Machine) and the problem persists. What do I have to do? Reinstall every app one my one without my Time Machine backup?

I did a fresh re-install from the recovery partition. Night shift still does not work... I have to erase everything and install from the scratch. This is very painful as I will lose half of my settings and configuration (especially the network drivers) despite the fact I use Time Machine 😔, ugh.

Hello, pinguch!

Thanks for using Apple Support Communities, it's great to have you here. I'm glad to give you a hand getting Night Shift to work as you're expecting.

It sounds like you've done a ton of really great troubleshooting but I'm wondering if you've tried testing this issue in a new user account? This can sometimes help isolate an issue to the root cause which in turn makes it easier to resolve. If you haven't had a chance to try that, I'd recommend giving it a shot by following the steps here: How to test an issue in another user account on your Mac

Another great isolating step is using safe mode to isolate issues with your Mac , as seen in that support article. To boot into Safe Mode:

Start up in safe mode

To start up in safe mode:

Start or restart your Mac, then immediately press and hold the Shift key. The Apple logo appears on your display. If you don't see the Apple logo, learn what to do.

Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.

To leave safe mode, restart your Mac without pressing any keys during startup.

I hope you find this helpful.

Best regards.
