About Calibration Issue on macOS Sierra (10.12.4)

2. Cause

New function, “Night Shift” is available from macOS Sierra 10.12.4 (Night Shift is compatible with 2012 and newer Macs). This function changes color temperature of the monitor automatically, so it might affect monitor adjustment. When you calibrate the monitor, above object monitors display color patches by software. Therefore, ColorNavigator cannot adjust gray balance correctly due to color temperature change by Night Shift.

3. Countermeasures

This problem can be avoided with the following two setting change.


3.1. “Night Shift” Off

  • Objective Mac: 2012 and newer (“Night Shift” tab is displayed.)

Select “Off” in the Schedule pull-down menu in [System Preferences] – [Display] – [Night Shift] tab (Default setting: Off) and uncheck [Turn on Until Tomorrow].


  • Objective Mac: 2011 and older (“Night Shift” tab is NOT displayed.)

The Night Shift function is not available with old Macs. You do not need to change the setting.


3.2 Change ColorNavigator setting

  • Objective Mac: All

Even when you set the Night Shift function to Off, this problem is caused by monitor’s color changing due to OS’s problem (*). At this time, we cannot avoid it by the setting of OS side, so please change priority setting of gamma adjustment of ColorNavigator to “Contrast”. Preset targets of ColorNavigator 6 are “Gray balance” or “Standard” and you have to create new target.

*There is a possibility that the problem may be improved by updating the OS in the future.
