I am a user of DisplayCal 184.108.40.206 and Argyll 2.0.1 on a Mac with macOS
10.13.6. I am trying to characterise the built-in display of my Mac laptop.
There is a black crush bug reported that means we must use special
profile only: single curve + Matrix with black point compensation.
Florian Hoch tells us this is a fix.
But some of us are seeing and reporting that even this profile is not
working now, and Florian Hoch is not able to offer a new bug fix suggestion.
Now I am having problems with all profiles except the default profile,
and this one is not good for viewing multimedia or editing photos.
Apple I don't think have fixed this bug now even in macOS 10.14.3.
Do users of Argyll CMS have any suggestions.
