MacBook Pro: light blue screen while closing programs

Hello to everybody!

I bought the MBP last July. Mac OSX 10.6.8 Leopard.

Until yesterday everything was ok.

I updated the software some days ago as requested. Every program is updated.


Here's the problem: closing the programs with cmdQ, the screen goes light blue. Forever. Yesterday twice: closing Outlook 2011 and, few minutes after rebooting, closing Google Chrome. I did the reboot and continued working, using also Outlook and Chrome. Nothing happened.


This afternoon, it happened again! This time closing Firefox. I didn't reboot, but I closed the screen as for standby, then re-opened, and the screen was ok again. Only Firefox was closed (as I pushed cmdQ before).


I have no idea of what's wrong with this Mac. Everything else seems to work perfectly. I am (was?) very happy to leave Windows for Mac...


Please help me!

I don't have strange programs and I'm so careful with it... (I have VMWare Fusion, but never used).

Please consider I'm new to Mac world, so I don't know what I can do by myself, I truly need someone to solve this!


Thanks in advance... I'd love to be still happy with my MacBook Pro!

Firmware Update 2.3 didn't fix it for me. Provided feedback to Apple 3 times. I don't know if they are doing anything about it. This problem has been viewed over 1700 times. If you are having the problem and want it fixed, please provide feed back directly to Apple. With the number of recent problems Apple's having, I'm starting to wonder if Apple has hired to many former Microsoft employees. When you spend more when you buy a computer, you expect more! 15" Macbook Pro Early 2011 OS 10.6.8.

I have a 15 inch MacBook pro that I bought this past April. I've also been experiencing this issue over the past few weeks. I get the blue screen sometimes when exiting an application. It isn't a specific app. It's happened with Firefox, Photo Booth, iTunes etc. I'm so annoyed that I spent $1800 on computer and get a blue death screen when I close an app.

You can temporarily correct the problem by turning off graphic card switching under apple, system preferences, energy, uncheck the box, until Apple hopefully fixes the problem. I don't know if Lion users are having the problem. I think it may only be a Snow Leopard problem. I'd switch to Lion but to many of my applications won't work under Lion and Lion users seem to have a lot more problems.

Correction...it is normal until the mac switches back to integrated graphics card. Download an application called gfxCardStatus and you can see every time your graphics card is changed. If you want you can leave the integrated graphics card in use and you will save battery life, if you want to leave the discrete graphics card it wastes more energy but some processes need it.


The reason why the blue screen comes when closing specific applications is because some automatically switch the graphics card to the discrete one (such as firefox or chrome, you can figure this out with the gfxCardStatus) and when they are quit the blue screen comes up because the system has switched to integrated.


Only the video, audio still works. So I believe that switching back to the Integrated Graphics Card sometimes results in a blue screen.


You can test this out by installing the application, setting it to "Dynamic Switching" (this just automatically ticks the box in system preferences) and open and close an application which automatically sets graphics card to discrete, such as photobooth. You will see a pattern in the menu bar in which it switches to "i" (integrated graphics card) when quiting and "d" (discrete) when opening. One time when you expect the "i" to show a blue screen comes up.
