The screen color of my 2011 17" Macbook Pro changes to blue-ish every time the discrete graphics card is used! That started to happen only after I upgraded to OS Mountain Lion!

 

Whenever I open any app that use Discrete graphics card by default, the screen becomes blue and looks terrible.. Applications include, VLC, Chrome (20.0) and I guess quite a few others!

 

So now efectively my Macbook Pro has just one usable video-card - the buit in one, because the discrete card (AMD Radeon HD 6750M) is not usable!

 

Here's some other forums set up about this problem, so it's not just me:

    I have exaclty the same issue. Whenever I start VLC or some other app that provokes the switch to the dedicated graphics, the internal display turns blue.

    Needless to say this also happens when I plug in an external display. In this case the external display looks just fine, again the internal one is blue, though.

     

    Looks to me like something is going wrong with the color management.

    Same issue for me; whenever the GPU switches, the color switches too (same color profile)!.

    I did the monitoring with "gfxCardStatus".

    The latest update released for Mac OSX solves the problem for me. I updated august 23rd.

    Hi! Great news... how did u updated? With a clean install or just via Software Update?

     

    My MBP is still at assistance waiting for repair, but if you solved the problem I think they will solve too.

    hello,

    version 10.8.1 (12819) solves this for me.

    MBP late 2011

    In mountain lion you can update via the mac app store, or the old fashioned way via the apple icon in the upper left corner and then software update Hope this helped!

    My case is the same with the first one of this thread I can't boot anymore... I have to try a force install

    Thank goodness!  I just updated to 8.1 and this is correct: fixed the problem 100% for me too.  SO glad this is fixed! Running Early 2011 MBP.

    Well, not such a good new after all guys.. at least for me.. After the update this appeared to be fixed for a while, however I just restarted my Macbook and the old problem has returned! The screen again becomes blue as soon as the computer switches to discrete video card!

     

    Apple - comon, fix this annoying thing!!!

  • diederikb Level 1 (0 points)

    Too bad, the same here. After a couple of reboots the problem is back..

    Same problem here, also after updating. I'm currently using gfxCardStatus to force the integrated gpu at all times as a workaround, but I really would like to see this problem fixed by Apple. Dedicated gpu is unusable right now...

  • Rodrigo Morbey Level 1 (0 points)

    after install 10.8.1 my MBP can initiate the OS (after some tries), but if I install gfxCardStatus and select one of it options a new yellow screen appears and I have to force shutdown. Again, after some tries the MBP can initiate but I don't feel free to try install any other software because I don't know when will be the next crash.

    Same here, the the issue was temporarely gone after isntalling the update to 10.8.1. One reboot later the issue reappears.

    I've got a 2010 MBP with intel SSD, and I've been having this problem ever since upgrading to ML.  The recent update to 10.8.1 didn't seem to work either.  One thing I havent had a chance to check with 8.1 is that if the blue tint appears when connected to power.  On battery mode it definetly does appear, but need to check when plugged in.

     

    Also, I think it happens because the MBP with the SSD is so fast on bootup that ML doesnt have time to fully load the colour profile?

     

    I've found a workaround that works all the time without fail.

     

    1. Once ML is loaded simply log off and then log back in. - This is what I do and it works everytime - no more blue tint
    2. System Prefs > Users & Groups > Login Options > Automatic Login = OFF. -  This will then prompt you to enter your password when starting up, therefoe slowing down the ML load process, which in turn loads the colour profile.  I don't like this method as I usually have automatic login, so I usually just log off and on again (1).
