When I enter Display Settings on Mac after hardware calibration is completed by PMU (Palette Master Ultimate), no information shows in the Display Settings page. Why does it happen, and how can I fix it?


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

If Mac OS shows blank page in Display Settings, it may be that the ICC profile count has reached the OS upper limit. This does not affect hardware calibration results.

We suggest you enter the ICC profile folder (/Users/USER NAME/Library/ColorSync/Profiles) and delete all of the old ICC profiles that PMU produced.
