kernel panic after installing el capitan

Hello

Recently I upgraded from 10.6.8 to El Capitan. Quite a big step for my macbook pro 6,2.

I was very pleased to notice that the hardware could afford the new os and that almost all my apps are still running fine.


Although, in the last 4 days I had two spontaneous restarts that the computer decided to do.

I went through some articles addressing the problem. One of them is this:

http://https://support.apple.com/en-us/HT200553

I have a very little clue that this might be happening when:

1. I run the chrome app.

2. doing often and fast trackpad gestures to move through windows etc...

So, in the meantime I'm going to use safari instead of chrome and see what will happen.


I checked the console for some more details but my knowledge can't go as far as kernel debugging.

The first spontaneous restart was last Monday and the Diagnostic Report says it is a "Kernel_2016-02-22-130219_[user name]-MacBook-Pro.panic"

After that, i had two more spontaneous restarts but without any kernel panic report in the console.

It seems to me that it could be a graphics related problem.

Today (26/02) i have stopped using chrome and the problem hasn't happened again.


Here I post the first "kernel panic" report in case someone could give me a clue.

Thank you very much in advance!

You have a GPU fault. It may have been there from manufacture as that model shipped with GPUs that were later found to have a manufacturing defect.

Many didn't discover the fault until they upgraded from Snow Leopard.

With the known issue, there is normally more in the backtrack, so you may just have another, unrelated failure in the GPU.


The free replacement offer ended years ago. I think others have said it costs about $360 to repair.

This is the article from Apple concerning the GPU issue - https://www.apple.com/support/macbookpro-videoissues/


Doesn't hurt to contact Apple Tech Support and see if they will still honor the recall. I had one just last week I had to send in due to this, but we had extended coverage on it, so I am not sure if it the the extended coverage, or that Apple was still honoring. It is just a call to verify.

Thank you both for your posts.

I think I read that somewhere.

Is it a motherboard replacement we are talking about?


Although, so far the mac is running fine after some changes I made in the Universal Access preferences about displays etc...

Also, I stopped using chrome and the system feels more stable. But I suspect that chrome is not able of causing kernel panics. is this correct?

Should I trust the latest stability that I notice and try to avoid replacement?


Thank you for your answer!

Thank you.


I had a look at the link cmoore01 posted and the affected models are:

Affected Models
  • MacBook Pro (15-inch Early 2011)
  • MacBook Pro (15-inch, Late 2011)
  • MacBook Pro (Retina, 15-inch, Mid 2012)
  • MacBook Pro (17-inch Early 2011)
  • MacBook Pro (17-inch Late 2011)
  • MacBook Pro (Retina, 15 inch, Early 2013)

My mac is a macBook Pro 15-inch Mid 2010.

In any case I'll have a check with apple here.


Thank!

You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by a recall program that has now ended.

The model was discontinued in February 2011. It's now classified by Apple as a "vintage product." That means Apple will most likely refuse to fix it (but see the exceptions on the linked page.) In that case, you would have to go to an independent service provider. The part may no longer be available, or the repair may not be cost-effective.

Often the problems start after an OS upgrade. If the upgrade was recent, and you have backups, then you can revert to a previous OS X version.

Otherwise, make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The testing will be free at an Apple Store—unless Apple refuses even to look at the unit, which it might. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue called "VST" (for "Video System Test.") Ask for it. A "Failed" result means that the fault is present.

If you do decide to go to an independent service provider, be aware that the replacement part may also be defective. Some owners reported that they went through as many as three replacement boards before getting one that worked. Don't expect any help from Apple if you're charged several hundred dollars for another bad logic board and the provider won't replace it again.

If you don't want to take that risk, or if you don't like the price you're quoted, you may (or may not) be able to work around the problem by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
