When I enter Display Settings on a Mac after hardware calibration is completed by PMU (Palette Master Ultimate), the error message “Settings Error” pops up, and no additional information is shown in the Display Settings page. Why does it happen and how can I fix it?


Please note that when PMU completes hardware calibration successfully, the ICC profile on your OS will be updated when you switch to calibration mode. 

Mac OS may cause this settings error message, but it is not related to the hardware calibration. Please contact Apple for further assistance or search "com.apple.extensionkit.errorDomain error 15" for more information.
