Question: How to fix colorsync errors ?

I was using my macbook air on routine basis that suddenly a layer of distorted colour appeared. Then i went to the colorsync utility and found six errors. i tried to fix them many times but unsuccessful. These profiles were locked. but i tried to find them in finder by

1. pressing shift+cmg+g

2.then pasting in go to finder.

3.then opening "get info".

4. then i tried my best to change the privilege of every one to read and write so that the profile may be unlocked and repaired but get the error that i don't have permission to do this. ?

Please help me.

MacBook Air (13-inch, Early 2014), OS X El Capitan (10.11.1), just used for one year

As I said, it sounds more likely to be a hardware issue.


I realize such screen issues can be difficult to descibe in a post, but "layer of distorted colours" doesn't tell us much. Can you take a picture of the screen and post it here? Use the camera icon to upload a photo, or drag and drop it into the editing window. If the digital camera you use takes large images, size it down to no more than 1000 pixels wide, first.

Thank you for the image. Yes, it's definitely a hardware issue. Profiles cannot create such breaks in the display no matter how corrupt one may be.


Take it in to an Apple Store if there's one near you. Expect it to be a rather expensive repair. Being just over a year old, they may, or may not give you a pass and repair it for free, but don't count on it.


If you purchased AppleCare for the Mac before its first year beyond the purchase date was up, then it will be covered for two more years and the repair will be free. If you don't have AppleCare, you can't purchase if after the fact. And the Mac is over a year past its purchase date, so you won't be able to get it anyway.

but it disappeared by its own now … I let is shutdown for two days and it was removed.

I would suspect the problem will return. If not, consider yourself fortunate.

but still i can't fix the errors.

Again - ColorSync profiles cannot in any way cause these kinds of screen display issues. A profile is an overall control of color. It can't, and doesn't manage device color in pieces or strips. Again - ColorSync reports all kinds of things as "errors" that aren't errors. There are all kinds of ways to build profiles, and they still work as expected. Some methods are deprecated, but are still functional, not errors. Here are my supposed "errors":

Note the third item, my current monitor profile of EIZO 11-4-15.icc (besides others) has the same "error". There's nothing wrong with it. A couple others are those I created with X-Rite's i1 Profiler software. I'm quite sure EIZO and X-Rite know what they're doing.


You also have to consider which profiles you're actually using. If none of the ones you have listed are being used, then it doesn't matter if they're the most corrupt .icc profile anyone has ever seen. "Not in use" = "can't do anything to the system". It's just a file taking up space on the drive.
