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
I think I might have found a solution.
Open a new Terminal window and type this into the prompt:
sudo /System/Applications/Utilities/ColorSync\ Utility.app/Contents/MacOS/ColorSync\ Utility ; exit;
This will then ask you to enter your macOS password. Enter it and hit enter. This will open up the ColorSync Utility app using root privileges. Be sure to leave the Terminal window open while you're working with ColorSync Utility!
Within ColorSync Utility click the "Verify" button like normal and let it report back the issues it found. Then click "Repair" like normal—it should fix the issues and will say so next to the files it has fixed. To confirm click "Verify" again. You should get a message saying "Verifying done. No problems found."
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!
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!
Check your Permissions for your Macintosh HD first. If needed, change to Read and Write for wheel and for everyone. Restart. Go back and try to change permissions as described in previous post. Should work without problems. Good luck.
With 10.15.5 update .icc files has been fixed. However, I'm still having blank/black screen issue on my extended display monitor (Dell U2412M).
My display is connected through apple's HDMI to DVI-D connector device. I'm getting blank/black screen on extended display. Tried almost every single hack I could find on internet.
This $ucks!
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 issue. Updated to Catalina 10.15.4 this morning.
I have the same issue, I followed the Safe boot process but the error is still on. Apple should do something about this...
I have only following options and have tried turning all of them on/off. Still no luck.
This also just happened to me after upgrading to 10.15.4. Must've been introduced in the update.
I have the exact same problem, /System/Library/ColorSync/Profiles/ITU-2020.icc appears in Profile First Aid and it says checking for 24 profiles. Is there a way to bring it back and get a new one
Can I have a new update to fix this update?
I have the same problem on Catalina 10.15.4.
Resolved
I too have the same problem. Do we have any solution for this ?
Colorsync utility can't fix the icc file ?
