Blue tinted screen after mountain lion

so maybe you had a different problem as I have, maybe with the same impact.

I really hope so my friend. Because I paid €600 for the new logicboard

uh, that's a lot of. but now you don't have any problems with a blue tinted screen? Do you use Filvevault and a SSD?

I use an SSD

With Filevault 2 activated?

No

ok then you definitively have a different problem.

I just ran into this problem. I replaced my old HDD with two SSD (in RAID0) for my mid-2010 2.66Ghz 15'' MBP, and reinstalled Mountain Lion.

It seems entirely software based and not hardware based, since turning off switching between mobo/discreet graphics (in Energy Saver) solves the problem permanently, and you don't have to do that every time you reboot if you lock the changes. The downside is that by always using the discreet graphics card, you use more battery... ho hum.

It seems like many people experiencing this problem have installed an SSD prior to the issue. I wonder if there's a correlation? It could be SSDs themselves (I went with Samsung 840 Evos), or more likely the fact that they probably installed Lion via the internet/installation helper, and not via an upgrade...?

Best of luck figuring it out!

Very similar setup/situation here: just upgraded my Early 2011 2.0 i7 MBP to the exact same SSD (840 Evo) and am having this problem with certain websites using Chrome (I tried the same sites on Safari and could not reproduce). I'm crossing my fingers the problem doesn't persist on 10.9.

EDIT: oh and I tried resetting the PRAM and it didn't fix it.

You have this issue with chrome because chrome is using the external graphics, too.

I pray Mavericks will fix this bug, hopefully they will release it today. 😉

There exists a workaround: beforce shutting down your Mac, untick "automatically switch external graphics" in system preferences, energy savings. After reboot, tick it again. Until next reboot, error is gone.

I wrote a little Apple Script, doing this automatically. You just have to run it manually beforce shutting down and put it in autostart for running automatically after reboot / login.

tell application "System Preferences"

activate

set current pane to pane "com.apple.preference.energysaver"

tell application "System Events"

tell process "Systemeinstellungen"

tell window "Energie sparen"

tell group 1

tell checkbox 1

click

end tell

end tell

end tell

end tell

end tell

quit

end tell

quit

Reset PRAM!!!

didn't help.

With Mavericks 10.9. the error is gone! Thanks Apple!

Excellent news!

I may be an early adopter of this OS.

Not sure if this is the same problem you all are having, but I'm getting a weird blue tint *just to certain windows* only AFTER upgrading to Mavericks. The dock, menubar, background are unaffected. Here's a screenshot: https://drive.google.com/file/d/0ByIfappGbi6iUk5xZ0RTUjRSOFE/edit?usp=sharing

Anyone else getting this? Any fixes?

Thanks, all.
