GPU Panic - OSX 10.9 Mavericks - Macbook PRO 6,2

Hello there,

Since upgrading to Mavericks here is what happens:

I use my computer without any problems, leave, it goes to sleep. I come back, it wakes up for about 5 seconds and has a GPU Panic and reboots.

I've read about the GPU recall for the Mid-2010 Macbook Pro. But my computer is older than 3 years, so Apple won't take it.

I understand they were clear about the rules of the recall. But then again, If I found out I screwed up in my work, I'd try to fix it, despite of how long later the damage showed up.

Anyway, here are the specs of the computer and the crash log. Anyone has any ideas what could be causing it? I've done a clean install of Mavericks, and it didn't fix it.

Thanks!

Macbook Pro 6,2

15-inch, Mid 2010

2,66 GHz Intel Core i7

No upgrades, stock machine.

Thanks. I was aware of that 300.00 fix, but don't want to sink money into this machine if I don't have to. Rather save it for a future MB. And for what I use it for, it's working just fine. It feels like a new machine the way it's working. Besides browsers, I mostly use it for writing, Garageband, and some drawing on Gimp. Nothing too heavy. So, I'm good.

Feb 15, 2015 12:56 AM in response to Musebean

I'm glad the fgxcardStatus workaround was useful to you. I also use it but I think it is not

what we as customers should be expecting from apple, "Yes is our fault but its up to you find a way to make your mac (partially) usable".

I do need to use some applications which require heavier graphics processing.

I also don't think we bought a macbook pro to settle for a browse-and-text-edit computer a few years after purchase (no disrespect intended).

Curiously, my original post was edited. I mentioned that people who bought the MBP 2011 affected by a similar problem also filled a petition
in the "Change" website, the one with .org domain.

Maybe we should do the same.

I agree. I have made an appointment at the Genius bar and will ask nicely for a free fix as I was never notified of any problem during the recall period (like Toyota has notified me when there was a recall), and everything was fine until Yosemite.

Went to the Apple Store on Monday. I explained nicely: the problem, showed The Genius my GPU panic reports, how the kernel panics started when I upgraded to Yosemite a few weeks back, how I troubleshooted with the GFXcardstatus app, how I had an expired 3-year Applecare and would have had gotten the fix if I'd known about it during that time, and that I had brought the MB in for service 2x before and no one mentioned anything about the existing flaw in the GPU card.

The Genius said for this problem that the fix was aprox. 300.00 and that Apple would pay for it. The Genius stated that the store had the prerogative or wiggle room to do so on this particular problem. I got the MB back today in 3 business days and it works fine so far. They even cleaned it up. It didn't look like mine for a moment because it was so immaculate.

As far as I'm concerned, this Apple Store showed integrity in my case. They did the right thing.

Feb 19, 2015 12:17 PM in response to Musebean

Congratulations - You are one of the lucky ones as they milked me for $300 to fix what should have been a product recall.

I was planning to put that $300 towards a new iPad but instead I am now the owner of a new Android tablet. 😟

Feb 19, 2015 3:45 PM in response to Musebean

Congrats!

Im glad for you and sad for me. I am sure I was polite in explaining the problem and all but no luck. I wonder whether it it because of the country, It's my impression that here in Spain customer service is not as "important" as in US.

Feb 24, 2015 5:59 AM in response to Jacob ESS

You are not alone although I am not from Spain.

I was also polite in explaining the problem but Apple's service in Hong Kong is also not as "important" as in US.

Feb 25, 2015 8:54 PM in response to Oberdan

Mine is doing it for the second time. My CPU was replace with no charge, out of warranty. I have a mid-2010 i5 15 inch MacBook Pro. It's starting again... Should I go back to the genius bar?

Feb 25, 2015 9:04 PM in response to bunlo

Wow, bunlo. Thanks for all those details. I have the same thing with plugging in an SD card and it not being recognized. I have to put it back in very gently, then it will work. That still happens after the CPU replacement. That might be due to needing new SD cards though.

You are brave to have that many photos on iPhoto. I've had OSX since the beginning. I had OS 9. I don't think iPhoto even existed on OS9, but somewhere along the line iPhoto really crapped out my photos, so I stopped using it a few years back. Something must have followed through with the photos I imported into Picasa. Now some of them are saying 1969 on the date and appear in the wrong folders.

I just wonder if Apple will replace my CPU again... whether it's possible that it's even the same issue that my CPU is going out again a year after it was replaced the first time.

After trying some fixes spreaded around the Internet, the panics came up again. I'm also in Spain and Apple Stores won't cover my problem. I'm thinking on reballing the GPU as a last resort choice. Has anyone had a good experience doing this? As far as I've read, reballing, when carefully done, using appropriate tools, may be a valid solution. However I'm not sure if logic board faults in 2010 MBP models have to do with bad soldering or they are caused by some other kind of design flaw. After having a look at this topic in macrumors I'm losing hopes on fixing this problem... (note: buying a new machine is not a solution)

Hi to all!

I have a MacBook Pro Mid. 2010, I think we all know why we´re here so? I just want to inform all of you after much reading and experimenting about the issues we´re having in our Macs.

I first though it could be a software problem. There is no sense why while running SnowLeopard, users experimented not such thing as frequent GPU or Kernel Panics until upgrading to Lion > Mountain Lion > Mavericks > Yosemite. I can tell by my own experiences, downgrading from Yosemite to Lion doesn´t solve anything, at least not that much. I haven´t been able to get to Snow Leopard for lack of DVD, probably this could be a solid solution. I hope, soon, have something to tell you.

Form me, I experience less GPU panic erros in Mavericks.

I have tried erasing "windowserver" files in Lion. Located in "Byhost" - No changes.
Fixes posted in this post before - Some better.
gfxCardStatus is one of the more reliable fixes. 1.8.1 version is the one that remembers last settings.
Clean installs from Lion to Yosemite with USB and DVD
All resets recommended by Apple

Another things to check out, is the <reflowing> in the GPU chip, I read some users got considerable changes.

Many people have their motherboard changed even 4 times. Could be a 50/50 solution, we do not know how long it will take for them to fail.

Please, keep in touch. Thanks.

Mar 17, 2015 12:30 PM in response to Johnnie2610

Hi Johnie! I've read very negative feedback about reflowing. There's no warranty that this solution will work for more than 6 months, and you can be sure the problem will return eventually. An alternative to this is reballing (detach the chip, clean it and solder it again using new tin balls). Being not 100% reliable, and also more expensive, it can last for much longer when carried out with appropriate equipment and knowledge. I've been thinking on taking my computer to a local repair shop and ask for this, but I still have some doubts. Both reballing and reflowing work with problems caused by overheating/bad soldering, and I'm unsure if that's the cause of our gpu panics or they're due to design faults in the printed circuit board or even a damaged gpu chip, in which a reballing won't solve anything and would put in risk the entire laptop operation. It would help a lot to know a little more about what causes our discrete gpu malfunctioning, however I haven't found any detailed information about this.

By now I'm doing relatively fine with gfxcardstatus, but using the computer for high resolution image editing has become a nightmare.

Mar 24, 2015 8:48 PM in response to cfbbaer

GPU PANIC? PROBLEM SOLVED.

Well, for me, anyway.... let me start with some background...

I have a Macbook Pro, mid-2010, which had Mavericks installed. I bought it on the cheap ($250), because the seller had this intermittent rebooting problem (especially using Netflix). I don't use Netflix, but I found it would occur everytime someone called me on Skype (black screen, then kernal panic grey screen message and auto-restart). Then after really trying to troubleshoot this, and after installing Mountain Lion, I realized the reboots occurred every time the camera went on (ie. opening Photo Booth). It also occurred every time a Microsoft Word document was opened, and rarely, it could even occur just opening a folder in Finder. I tried every possible update and security update offered for Mountain Lion, no change. I finally learned the older gfxcardstatus will not work with this system, because of a bug in ML. And trying to turn off video switching in the Energy panel of Apple's preferences instantly caused the laptop to reboot! Moreover, it retained its switched-on setting after reboot! It worked fine in safe mode, because safe mode does not do video switching, but that setting does not keep after rebooting into normal mode. (n.b. I did not find this problem was caused by one video card or the other. Rather, it was caused by the act of switching between the cards. Because as far as the not-random reboots are concerned, there was no difference in the behaviour of either card).

Then I tried installing Snow Leopard; which is supposed to be the original preinstalled system (10.6.3). But every copy I could get my hands on would not install. It appears only the install DVDs that came with the laptop will install (on account of the mbp drivers), and I did not have those. However, a copy of Lion 10.7.4, despite not being mbp-specific, did install fine. (n.b. Apple says there are separate video updates for SL and Lion that are supposed to help this problem, but not for Mountain Lion or presumably later systems; because they were already incorporated. They are in no way saying this means the problem is fixed by using the earlier systems, only that it could help to install the video-patch updates...).

So the deal is, the older gfxcardstatus (1.8.1) does work under Lion. So does removing the video switching checkmark in Energy settings. Now, it does not seem to matter whether I am on the Nvidia card or the Intel one, the video camera works and does not cause reboots when it is turned on in any application. Best yet, the setting finally sticks after a reboot. The newer versions of gfxcardstatus are useless here! I have configured gfx to open only the Intel card, simply because people seem to be saying the Nvidia gives the most trouble. I haven't used the system too much yet, but so far, everything is working that didn't work before!

And I figure I saved about $1,750.00 on the price of my Macbook..... 😉

p.s. I am considering the possibility the GPU panic problem of mid-2010 (etc) Macbook Pro's may be caused by different things for different Macbook owners. e.g. I found the my reboots could be replicated; and only occasionally did the computer appear to reboot out of the blue, without being triggered by opening a program. Others seem to be more plagued by random reboots than, say, video camera triggered reboots. So while my problem may be caused by a defective video card switching component, the source for similar symptomatic behaviour may be along the lines of dried up heat paste or such.

Either way, this all points to shoddy workmanship and defective parts from Apple computers, and if Apple is such a great company that cares so much about its reputation and customers, it should stand behind its clearly defective products no matter when they were purchased!!

Because Apple is not willing to stand behind its products, I am not willing to buy any more Apple products in the future.
