    I am using Mac OS and created profile with ColorMunki Photo + DisplayCAL3.35

    Please take a look at the screenshots

    When viewing images by “Apple Preview” APP
    The BLACK POINT on “Apple Preview” is DIFFERENT from
    the BLACK POINT on “Finder Preview” (Correct Blackpoint)

    The BLACK POINT on “Apple Preview” is much darker,
    Any Less than 4% on image is already Completly BLACK
    but on “Finder Preview” it can still identify the differences between 1.6% & 4%

    BUT created profile with ColorMunki Photo + Official APP

    When viewing images by “Apple Preview” APP
    The BLACK POINT on “Apple Preview” is SAME AS
    the BLACK POINT on “Finder Preview”

    which is normal

    Because the new version of Lightroom Classic CC, use the black point as same as the images on “Apple Preview” APP
    which is way too dark, so I can not use the profile created by DisplayCAL anymore.

    I have tried to check and uncheck the “Black level drift compensation” on the DisplayCAL, but it does not work.

    Also, I had tried to set custom gamma and black output offset setting on DisplayCAL, it does not make any difference

    This is not only happening just on one mac, My Mac Pro with an external monitor and my iMac, Macbook Pro, with different OS version also have the same problem.

    Did I set anything wrong? or it is a bug on Mac? Thanks a lot.

    This is a macOS bug in Preview and some other macOS applications. There are already a few threads discussing the issue, although there is unlikely to be a solution until Apple fixes the underlying bug(s).

    Thanks Florian, but if it is a bug, why it does not happen when using  ColorMunki Official App to create profile? it may be some setting in the profile file itself right?

    From what I’ve seen, literally coincidence. I’ve it seen with i1 Profiler, basICColor, and others (which is no surprise since it’s potentially a bug somewhere in the Apple CMM, not in the generated profiles).

    There is a link to send a bug report to Apple in one of the other threads I mentioned.

    The important thing is that it is a rendering bug related to Apple’s color management implementation (doesn’t happen with e.g. Photoshop, only happens on mac). Just give them as much and as detailed info as possible.

    is that possible can you provide the threads’ link? thanks a lot

    SOLVED

    In my case…
    I use EIZO display with its calibration software “ColorNavigator” and calibrated profile.
    When a profile made with an option, “reflect black level in tone curve” is checked, shadows get too dark.
    Uncheck the option and re-calibrate (= renew profile) fixed the issue.

    about
    “reflect black level in tone curve”
    is DispCal has this option?

    We don’t even know if the person really had the same problem, neither do we know what “reflect black level in tone curve” does in the EIZO software. Discussion should continue in the other thread I linked above, I’ll close this one shortly to avoid redundancy.
