Q: Screen colour temperature changes (bluer) when running web video, iDVD

I have the same problem. OS X 10.8.2 on MacBook Pro 15 "Early 2011.

When I switch from onboard video to the discrete changes the color temperature. Using GFX card status the problem is obvious.

I tried all the steps in the previous post, I thought I had resolved but now the problem has come back!

Has anyone found a solution?

i created a new profile and there isn't the issue, then i see in this profile there isn't the ColorSync folder.

so i back to my original profile and i remove the ~/Library/ColorSync folder, restart and i fixed.

sorry for my english.

I did as you said but it does not work. Once off and on again the problem returns.

The issue is Adobe AIR! Uninstall it! Worked for me.

Unistallung adobe air and restart works for me! I have macbook pro mid 2010 with mountain lion!

You can reinstall the latest version of Adobe AIR without any problems. I no longer have the problem.

I think the bug was only present in previous versions.

If it does not go you can always uninstall it!

I thought the problem solved but it didn't, it comes and goes

its really annoying

APPLE FIX IT!!

The problem has come back to me! It's getting very annoying!

I have this problem too, I managed to find the error in the console here https://discussions.apple.com/message/20162986#20162986

Since then I have tried to fresh install to find if an app was the problem, as Apple Geniuses were suggesting: it's not. I installed only Byword over 10.8.2 and it becomes blue.

Using a different Color Profile than the native one solves the problem, but they are blue!

Any updates on how to solve it?

Hello everybody,

Thanks for the feedback.

Didn't work for me..

This is definitely a problem with the switching to the discrete Nvidia card.. gfx status helps by not allowing it to use the discrete card, but this is not an ideal solution..

For me, this tutorial works perfectly.

Since, I have no problem (color temperature) with automatic switching.

And for a colleague's MacBook Pro, it works too.

With 10.8.3 the problem persists!

I'm on 10.8.3.  My path was a clean install to 10.8, migrate user settings, then upgrade to 10.8.2, then 10.8.3. MacBook Pro 6,2.

Here's what fixed it for me.  Shut down.  Start in Safe Mode; when the system comes up, shut down again.

I've been using my MacBook Pro for a couple weeks and so far the fix seems permanent.  (You can verify that the system is switching the graphics cards by looking at About this Mac - the active card will say Main Display)
