Blue tinted screen after mountain lion

new game, new luck... 10.8.5. beta 1 released.

Are you going to try 10.8.5?

I'm getting ready, for an unrelated troubleshooting issue, to setup a test version of 10.8.4 on an external drive. This might be a good place to check if 10.8.5 fixes the color issue, with reasonably low risk of screwing up other things. Hmmmm.....

Not yet publicly released beta OS versions should not be discussed in these forums.

If someone were to find out & share with us that it fixes a longstanding bug like this one, what's the harm?

Anyone already tested 10.8.5 final?

I tried everything and finally my logic board just gave out. Puff. Doesn't work any more. Apple will not replace it, even though it is obviously an issue that hundreds if not thousands of MacBook Pro of this generation have. So, I ended up buying a new logic board. No problem now. All is fine. It is a HW issue that can't be fixed unless you replace your logic board.

I can't believe this should be a HW problem, because the problem doesn't exist with 10.8.1 or 10.7.

With 10.8.5 it still exists. I give up and wait for Mavericks.

That is what I thought. If you read in the comments, there are quite a few of us that have had to change their logic boards. So either the HW is faulty or one of the Firmware or OS updates made by Apple, caused the second graphics to overheat and crash and burn.

10.8.5 does not fix the problem here. Hard to believe it's a hardware problem when it happened with the change in OS (for me, change from 10.6.8 to Lion, IIRC), and specifically now is triggered by particular programs like Citrix.

With me the Problem is triggerd by programs that are using the external graphics.

I don't believe it is a hardware Problem at all. Logout / loin fixes the problem temporarly, so this wouldn't work if it is a hardware problem.

I don't think Apple gonna fix this in ML, maybe with Mavericks the problem will be gone.

That is exactly why it is a HW problem. As soon as you triger the external graphics card it happens. If you download software for managing the graphic cards, and you disable the external via software you will see that the problem with the programs you use will not exist any more. But, this means that one day your HW will fail, like it happend with me and many, many others.

Good luck man.

How could this be hardware problem, if you do logout / login and the problem never appears until next reboot?

When you log out the processes that use the external card stop working until they are triggered again by another software. Look, I learned this the hard way. I paid for my logic board and now I am ok.

Good luck man!

I think you don't understand me. I log out, log in again, start a program that uses the external graphics and the problem never appears until next reboot. So there is a situation using the external graphics without having a blue tinted screen. Ergo i can't be a hardware problem.

I have been there mate. I have done it as well and I thought the same. Then one day puff!

Anyway, I wish you luck man
