Hello, I am a new Macbook user. recently I was changing display colour profile and somehow I find out there it's file call ITU-2020.icc can't fix with ColorSync utility. Please help Thank you
/System/Library/ColorSync/Profiles/ITU-2020.icc
Header message digest (MD5) is not correct.
The file is locked. Could not be fixed.
MacBook Pro 13", macOS 10.15
Go to Macintosh HD/Aplications/System/Librabry/ColorSync/Profiles/ Scroll down to ITU-2020.1cc Select the profile, Right click on it, Get Info, Change Permissions To Read and Write for wheel and for everyone. Run ColorSync Utility, Verify. Problem solved!
when I spoke to apple support the told me to delete browsing history. you can go make an appointment to speak to them about your problems. I don't work for them.
Any update on this? I am facing this issue as well.
Did the steps help you?
No, I am still having the same issues. Let's hope Apple will fix this problem for the next update.
Sorry for a typing mistake Go to Macintosh HD/Aplications/System/Librabry/ should be Library.
I have the same issue, I followed the Safe boot process but the error is still on. Apple should do something about this...
Hm. I have the same LG 4K monitor, but the problem (a blueish cast) is still there after the 10.15.5-uprade ... :-( . How can I find out if the ITU-2020.icc file has been updated?
@GeorgeMartini,
I can't seem to find 'high dynamic range' option anywhere in my system prefs. Could you please share the screenshot?

I have only following options and have tried turning all of them on/off. Still no luck.
Yes, I went though this step. But when I wanted to change permission, I encountered this:
The operation can’t be completed because you don’t have the necessary permission.
Tried to change to admin mode by doing this: https://www.imore.com/how-turn-system-integrity-protection-macos
But still can't change the wheel!
Nicely done. I hope it help others here. I ended up upgrading my MacBook Pro (from 2019 to 2020) for other reasons, migrated my old MacBook data, and the problem disappeared. I hope this works for others.
Same issues as everyone else. The "fourth, go to history and clear history" step is super confusing.
Thanks. Yes I did. But it doesn't let me to change it even as Admin for Macintosh HD. I think they really messed up with this new update.
Colorsync utility can't fix the icc file ?
