On my mid-2010 MBP (nVidia GT 330M), when switching to the discrete card the color rendered becomes "cooler" (more bluish, greenish) than the one rendered by the integrated Intel card. This does not happen everything but 8 of 10 times it will happen, and when it does happen it is very noticable as if I look at the screen through a light blue transparent film. I suspect it is a driver issue.

 

Anyone with the same symptom?


Macbook Pro 15-inch 2010, Mac OS X (10.6.7)

    I have a MBP 17" early 2011 with integrated Intel graphics and a AMD Radeon HD 6750M graphics card. Since I upgraded to Mountain Lion today I have the same symptoms. Every app that uses the Radeon card changes the screen to this more bluish colors. It is reproducable by opening System Preferences -> Save Energy -> and select "automatic change of graphics mode" (the setting, which always uses the high performance graphics card). I think it is a bug in Mountain Lion and will be fixed with the next update. At least I hope so...

    I have the same issue with yours.

    My MBP is mid-2010 with Intel graphics and Geforce GT 330M. After I install the mountain lion ver. 12A269, when i switch to GT 330M graphics, the dispaly will be bluish.

    It's very  strange!

    UPDATE: After installing Mountain Lion I did not reboot the computer and I encountered this issue. But after a cold restart the issue is gone at least for now. I'll have to watch this....

    Same issue and this has made it so that I am unable to do my job.  I am a photographer and I depend on the color temperature of my display.  I am not able to properly edit photos as the hue keeps changing between warm and cool as the video graphics are flipping back and forth.  Is there any offical word from Apple on this??

     

    I have tried to reboot and the issue still persists.  Very easy to make it happen.. just have to open photoshop.

    I've got a mid 2010 Macbook Pro and I also have the exact same issue with the blue tint when running Photoshop CS6.

     

    Doing a forced restart (holding the power button) temporarily solves the problem.

    I found out that if you turn off automatic graphics switching and restart, the color temperature is correct. You can then turn on AGS and switching between integrated/discrete card does not cause this issue anymore... until you restart your computer that is. So in a word, if the Mac *boots* with the discrete card, it behaves correctly when switching between cards; if it boots with the integrated card, it *usually* changes color tempeature when switching.

    This works for me too. I'm sure Apple will address this in one of the next updates of ML.

    Same problem here with Mid-2010 15" MBP. Has anyone tried to reinstall Mountain Lion? It seems to have fixed the problem for a few persons. I will try tonight.

  • jianglai Level 1 Level 1 (0 points)

    update?

  • amadex Level 1 Level 1 (0 points)

    This is also happening to me, at least on Chrome and Adobe Illustrator... any update?

    Apple will only resolve this issue if they a.) know about it and b.) know that enough users are having the same issue. So thought I'd add myself to the list of users having this problem.

     

    Jianglai is right. What a strange issue. Basically, the workaround is to always uncheck "Automatic graphics switching" from Energy Saver in System Preferences whenever you need to restart your computer. Then re-check it after the restart. If you restart with it checked, the color temperature of the display will go blue whenever the discrete graphics is turned on. The colors are as they should be when the integrated graphics is turned on.

     

    I have a late-2010 MacBook Pro 15", and this issue has only occurred with Mountain Lion (did a fresh install). Any application that uses discrete graphics will trigger the problem, such as iPhoto or Quicktime/iTunes with 1080p content.

     

    Anyone who has tried reinstalling Mountain Lion please tell us whether it has fixed the problem or not.

    the problem is for macbook pro 2010 with ssd installed.

    mountain lion cannot load the discrete graphic driver well and it mistakes when it switch to this using some programs (like chrome, ps, Transmission and so on)

    by now u can just logout and login after every restart to fix this.

     

    i hope they'll fix it forever in the next update.

    Mine doesn't have an SSD and does the same thing.
