Macbook Pro screen becomes blue every time a discrete graphics card is used!

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.

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...

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).

My problem just disappeared - can't recall if I was running Lion or Mountain Lion at the time. I do use gfxCardStatus and just set my card to discrete only and it worked - then one day I set it to dynamic and the problem was gone. It does seem to be a software glitch - but one that was mysteriously 'fixed' for me.

Now, even on battery or adapter, I can dynamically switch with no blue tint. I don't know why, though, nor why some more users are having the problem.
