Q: fequent mid 2012 macbook pro retina kernel panic reboots possibly GPU related

I've been having a lot of what seem to be kernel panics, usually while watching/forwarding flash videos (e.g. on youtube) and or toggling between full screen or not or using Adobe Bridge and toggling between full screen or not.

 

What happens is that the screen goes blank (if I hit the keyboard I hear dinging sounds) and the screen goes blank, and I have to force a power off/on.

 

This has happened as often as 10 times a day.

 

I took my computer into the apple store, they ran their extended diagnostics and found nothing.  The tech said it could be a logic board error, but because all the logs in the console were kernel panics he suspected it was the OS.

 

I reformatted the drive, reinstalled the OS and it ran fine for a day or so with minimal new software, including on youtube etc.

 

But today, I installed more software (Photoshop CC, a java based game, some extentions to firefox, and I experienced two panics today while viewing flash video.).

 

Anyone have any ideas?

 

I'd hate to shell out for a logic board replacement since I'm out of warrenty (just).

 

Thanks!!!

    At this writing, Apple has not acknowledged that any sort of Systemic problem exists with these Macs.

     

    To solve your problem, you should pursue repair of your Mac as if it were the only one that had failed.

    I have the same problem on mid 2012 15 inch retina MBP. Clearly due to the NVIDIA gpu. It happens every single time the discrete GPU runs (gfxCardStatus currently is forcing integrated graphics so that I can write this). The crash never happens on integrated graphics. This happened a few times over the last year but I never thought anything of it. It really started to happen regularly 1 week ago and now the discrete GPU is unusable. The machine has been out of warranty for 9 months. This is cearly a hardware defect and I'm not excited to replace an expensive logic board on this well-cared-for machine.

     

    Here's hoping that Apple will recognize a systematic problem.

    We have no way to escalate any issues from here on the forums.

     

    Your appointment at the genius bar for an evaluation is FREE, in warranty or out.

     

    And that is where you should make contact with Apple Inc and start to get your problem resolved. Do not assume that this is a prevalent problem that Apple will spontaneously resolve. Despite several reports, only careful diagnosis at the genius bar will get Apple to provide a fix.

     

    You should assume the fix they provide applies only to your problem. Other users will also need to contact Apple and get their Macs evaluated. If a trend is discovered after careful analysis, Apple may start a special program to address the problem. Do not wait for that to happen -- it may turn out that two reports of the same symptoms are caused by completely different issues.

    I just had my logic board replaced on my mid-2012 MBP 15" Retina for the second time. I'm 10 days in and so far, so good with the new logic board (although I haven't tried setting the main in-computer monitor to scaled mode yet). Apple also replaced the screen as it had some dots/pixels missing.

     

    Does anyone have any procedure which can reliably be used to reproduce the problem when required? Someone said something about running a Youtube video on one screen and a HD Vimeo video on a second screen?

    I reliably reproduce the problem by running a graphics intensive application like a game and making sure that the discrete GPU is being used by forcing it with gfxCardStatus.

    I don't think there is a reliable way that works for different machines yet.  The failure seems to happen when switching modes, either when under load or after a high load ends.  Some have been able to force the fault by pressing on the bottom near the display which may impede the cooling.  I could never do this.  The only consistent  observation was that infrequent crashes grew in frequency up until only a few minutes of uptime.

     

    It is a nuisance but that is what it is without a generic fix.  To reliably demonstrate a fault to the Apple techs, you will likely need to wait until the crashes occur every few minutes, which will be maddening to live with.

     

    In my case, the repair tech took my word for what was happening, concluded it was the logic board and charged me, and Visa approved the repair under the extended warranty and sent me a check.

    Thanks Peter. I was lucky enough that my machine crashed in the hands of the Apple Store Genius, and he was unable to restart it (which hadn't actually been a problem before then). So then there was no hesitation and he ordered the logic board be replaced (and the screen).

     

    The repair itself wasn't without problems. It was scheduled to take 3-5 days ("we'll call you"), but when nothing had happened after 8 I called the Apple Store. According to the guy I spoke to the repair was on pause because they wanted to make sure I had a backup of my data. When I asked why, they said it was because they were going to do a fresh reinstall of my operating system to see if that fixed the problem.

     

    I'd already been advised to reinstall the OS from scratch after the previous appointment at the Genius Bar (when I was already on my second logic board), so I'd reluctantly agreed to try it, spent hours reloading my data from Time Machine etc etc, but it hadn't helped and the crashes were still coming thick and fast. So I told that to the guy on the phone and he advised me to come into the Apple Store and sort it out, which I did, and then it was agreed they'd replace the logic board and screen immediately. They did the repair overnight and called me the next morning.

     

    So now I'm on my 3rd logic board and my main worry is that there's some kind of systemic issue going on here and the crashes are going to start happening again soon. Sure, the machine reboots pretty fast once you've deciced to kill it, but I work a lot in terminal sessions on remote machines, plus it even died once in the middle of a Skype call and once whilst showing a company demo video to someone.

    Sam, is there anything unusual about your work environment that might be blocking or limiting the cooling?   

     

    My understanding from the repair tech who did my computer was that mine was the first MBPretina that he had seen with this problem - hopefully it is rare and you've won the lottery twice and won't a third time. 

     

    I have no idea whether the display replacement is somehow connected with your logic board problems.

    Re: reproducing the problem

     

    In my experience, showing the apple techs the Kernel Panic related to GPU is enough for them to start the repair process. Mine was not under warentee so they did not consider whether it was an in, or out of, warentee repair.

     

    After the first motherboard replacement, what reproduced reliably for me was being in Netflix with video showing, and attempting to type. Rendering a font glyph (like going to Searchlight) would immediately freeze the machine with no hope of return. This was not a kernel panic, just a freeze (which leaves no logs). The symptom was different on the old motherboard, with kernel panics happening randomly every day (although always on the nvidia GPU).

     

    Although I am distressed that Apple is not taking responsibility for what seems like a defect in either the cooling system or the parts, and I am distressed that apple is still learning about the failure (a simple motherboard replacement did not fix the problem in my case - the "sensor" system (temp sensor? fan?), and a reformat of the hard drive) did solve the problem, which implies this is not _just_ a GPU problem.

     

    But fix it they did, and at least I have now a well working machine - after $550 and 2 weeks of repair time (and a lot of apologies from the genius. Those are inexpensive, apple has trained them well.)

    This is manufacturing fault and you are not alone juct check this post https://discussions.apple.com/message/25418402#25418402

     

    Apple even do not want us to raise our voices just check replies there.

     

    This fault for all macbook pro, imac etc from 2010 to 2013 and still Apple not fixing and replacing.

    Hi folks,

     

    add me to the list. 

     

    -I have a retina MBP 15-inch Mid 2012

    -suffering GPU problems which lead to black screen and computer crashing.

    -graphics intensive stuff seems to provoke a meltdown--for example, scrolling through hundred page PDF's, looking at large architectural plans, etc..


    haven't taken this in for evaluation at the genius bar yet but should do when work permits.

     

    I have tried some things and they seem to have helped avoid the GPU panics so that I can at least get some work done.  Curious to hear from those more knowledgeable about these band-aid measures.

     

    First, as mentioned in earlier threads, I installed 'gfx card status' to keep the laptop in 'integrated only' mode when using it unplugged from my external monitor.  That seems to avoid GPU crashes when operating the macbook as a laptop without external display.

     

    Here's what I've tried with some success to keep the macbook running while plugged into the external display.  These measures were based on my guess from the info I gleaned here that the GPU crash occurs during periods of intensive graphics usage and may be related to the heat generated during high-graphics-usage:

     

    (1) I downloaded 'Display Menu' from the App store (it was free).  This creates an icon on the screen's menu bar where you can downscale the resolution output from the laptop to the external or internal display.  When my macbook is plugged into the external monitor, I use 'Display Menu' to keep the output resolution dialed-down from the 2560x1440 optimal setting (for example, I've used either the second or third most optimized resolutions in the 16x9 format shown under the 'Display Menu' options: either 2048x1152 which is reasonably sharp or 1600x900 which is fuzzier but has larger icons/text).

     

    (2) I downloaded 'Macs Fan Control'.  This creates an icon on the screen's menu bar where you can manually ramp-up or ramp-down the two fans in the macbook case (each from 2151 rpms to 5917 rpms).  When plugging into the external display, just for good measures, I ramp the fans up a little--say to 3100 rpms each.  Because the laptop sits aside from and slightly behind the thunderbolt display, I don't notice the increase in noise when cranking the fans up over 3000 rpms.

     

    So far, knock on wood, I have been able to resume my use of the thunderbolt external display and appear to once again be able to unplug the laptop and plug it back in to the external display as business requires without provoking a GPU crash.  Not ideal.  Really need a permanent fix.  But this seems to work as a limp-home method.  What's next?  Duct tape?

     

    Do those here more knowledgeable want to comment on the steps I outlined?  Are these steps likely to help others?  Is it just coincidence that I'm able to use the external monitor again for now?

     

    thanks

    This is helpful Ed, I'm in the same situation. I'll give that a try!

    Ed - this is really helpful and might just allow us to keep using our machines with external displays. I downloaded Macs Fan Control and so far so good!

    If the problem is thermal and progressive, these steps may slow the progress and possibly provide some temporary relief.  I did not lower resolution or force the computer into "integrated only" mode but did try the fan control.  I also reset the SMC prior to doing this for a comparison.  When I did this, we were at the few crashes a day stage and this did not provide much improvement.  Within a week we were at the crash every 5 minutes stage.

     

    Keep an eye on it.  I suspect this will reduce the progressive nature of the failure but I don't think this is a fix.  I think Ed is correct when he calls this the limp-home mode.
