My Macbook Pro (15" early 2011) got blue screen every i normally booted it. It only can enter the OS when it's in safe boot. Solution please.

My Macbook Pro (15" early 2011, Mountain Lion, but after reinstall i change it to snow leo) got blue screen every i normally booted it. It enter the OS only when it's in safe boot.

I've tried any solution that i got from the internet, such as:

-Reinstalling the OS X (normal install & clean install)

-Reset PRAM and SMC

-Repair Disk Permissions and Repair Disk from Disk Utility (the result is OK. There's no problem)

-Repair Disk Permissions manually (with Command + S at the beginning of booting)

-Checking Hardware from Application Installer DVD (result is OK)

-Checking from Mac Resource Inspector/MRI (result OK)

-Booting from Recovery Disk is same problem, blue screen

All of that solution is not working. My Macbook still got light blue screen and sometimes blue screen with lines after apple logo and spinning wheel is shown.

HDD is in good condition because when it's checked on the other macbook it can be booted. But if you must know, other HDD can't be booted when its plugged to my macbook (blue screen again). If i do safe booting, it works but can't play video and music also photobooth. I got confused with this case.

Any solution or comment? Thank you very much by the way

Hi Idwan. I guess you already tried to boot the computer without connected peripherals, but if not, yo should try that (no external displays, USB drives, etc).

Before this problem, did you have any video issues (screen corruption, white//black/gray lines or dots, displaced parts of the image)? Did you notice any recent increase in temperatures?

Best regards, Proteo.

I always boot without connected peripherals.

This problem came when my brother playing game (Counter Strike 1.6, Mac) but it played from guest user, not from my user account. He play it for about 10 minutes and suddenly the screen goes blue. Since that moment, everytime i boot, the blue screen is shown (sometime with lines, sometime black screen).

Oh ya, i just remembered that i've got Kernel Panic in this problem (gray screen with 5-languages warning text)

However this problem is shown that time, it still can be normally booted after 3-5 times boot. And then i decided to do Reset SMC. Since i reset the SMC, my macbook can't be booted. Normally booting is never succeed. And it's been a month sice the reset.

Is playing game from guest user caused this problem?

Just next couple minute since my question is posted, i got the solution!

My macbook one-month problem is solved. Thank God.

I recognize that my problem is can't normally boot and only boot from safe boot. Safe Boot is way of booting that ignored reading cache and preference files in the OS. Normal boot is reading that thing and if i run it normally, it got blue screen. So i assumed that something not right on my cache or preference files.

Finally i find a software called Applejack (i interested with this software because it can fix cache and preference problem) and offcourse i downloaded it. I learn about the installation and the usage. I run single-user mode (Command + S at startup) and run applejack on it. It Works!!!

HOPEFULLY MY SOLVED PROBLEM CAN HELP ALL OF YOU WHO FRUSTRATED BECAUSE THIS BLUE SCREEN.

Hi. I'm not trying to rush things, you may have a different problem, but your issue looks quite familiar to me. I recently had a problem with the discrete graphics card (the Radeon GPU) due to overheating, all because a faulty application of the thermal compound in the factory.

In my case, the problem started slowly and intermittently, a few days after a gaming session (Quake 3) of about three hours (at the moment, I didn't realized that could be linked to the problem).

This issue is being actively discussed in another threads in this forum, but so far there's enough evidence that it's been causing similar problems for 2011 MBPs owners: screen corruption, black/blue screens, and in some cases, a total inability to boot. Some of the threads I'm talking about:

https://discussions.apple.com/thread/4766577

So far, and since the problem seems to affect only the discrete GPU (that's why you can boot in safe mode) a possible solution is to disable it by removing some extensions which prevent OS X from loading the Radeon drivers. This post describing the process (there are different files involved depending of your GPU version, so make sure you are moving the right ones):

In the case your discrete GPU survived and is not permanently damaged, I personally had success by changing the thermal compound myself, which completely fixed the problem (at least for now). I've posted about it here:

I hope you can find a solution, believe me I know the feeling when you see your expensive machine turning into a brick and it *****.

Good luck!
