Always when i try to turn on night shift nothing changes and i can see following error messages in the logs:

ColorSync: ColorSyncProfileCreateWithDisplayID failed to get profile for kColorSyncDisplayDeviceClass

Does anyone else have this problem or knows how to fix it? Thanks in advance!

  • Try using the Colorsync application first aid to repair and verify the profile. – Unassuming Guy Mar 19 '18 at 19:31
