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

Possibly good news (quote from Apple chat) for anyone covered by European consumer law. Mine is booked in to genius bar on 23rd Nov. Will post outcome/diagnosis. In the meantime it's running fine on just integrated GPU using gfxCardStatus even running photoshop CS5 and playing a movie.

In the UK (and other countries), many hardware issues are able to be directly covered under Consumer Law which would include this issue as well. The Apple Store will be able to better go over that with you at the time of your appointment once you take it in as well.

Mine had been having the GPU panics quite regularly so when Yosemite came out I tried to do a clean install but it never made it, just kept crashing so I took it into the Genius bar and they shipped it to Texas for the logic board repair for $310. I got it back a few days later and all seems well. It has frozen a couple of times but I don't think it's video card related. It just freezes, nothing works and after about a minute it reboots itself. Seems to only happen while using Safari.

Seems like a lot more people are seeing this problem, I wonder if Apple will step up here like they have in the past and fix this issue!

Hi Conor here again from Ireland. I told you my mid 2012 rMBP started crashing in August of this year when I connected it to an external LG 34" monitor. It never crashed before then and crashed after only a few weeks connected to the external LG monitor.

I have been following all the posts with interest and the feedback is great. At least I know I'm not unique.

First of all EU law gives 2 years of a warranty so mine was out by something like a week. So that's that I'm afraid.

Secondly I note people are saying not to go near Yosemite OS. I found it great and recovers quickly after a crash. Mine used to crash regularly with Mavericks if I had to update software that required a restart or I over extended applications, using the Intel 4000 integrated graphics and it switched over to the NVIDA card. I then had to go through a hard restart and 30 minute wait period before it switched back again. With Yosemite I restart and close the hood. I leave it a minute or so and when I lift the hood again and Yosemite reawakens it switches over to the integrated graphics immediately.

Thirdly after my first few crashes the NVIDIA card never came up when I ran a System Report. But a few weeks ago when I checked on a whim it had miraculously reappeared. My rMBP still crashes but the system still recognises the card whereas I thought the chip was fried and gone gone.

Has anyone tried SMC fan and driven the fan speed way up or placed the base on a large cooling surface or a fan assisted stand?

I used to use one with my last MBP, late 2007. Which incidentally Apple to be fair replaced the graphics card/logic board after 3 years when it had a similar problem (I assume).

Bye for now. C

I'm running SMC fan with it turned up (it makes no sound anyway). Seems to keep it much cooler and heat seems very much the thing that causes the GPU panic (at least in my own case). I can flog the NVIDIA card for a while but as soon as it gets hot it's game over. Have not had a GPU panic running gfxCardStatus on Integrated only... until last night. It appears the gfx setting had gone back to Dynamic Switching so that's worth keeping an eye on.

I found this thread because I had the same problem. I edit semi large format graphics for motorcycle wraps so the file is a few layer in Photoshop. I noticed it was more prone to doing it when my macbook was on my actual lap, so the bottom of my case was holding in heat from my legs. I took the bottom panel off and blew out the dust and still had problems randomly.

Last night it was really bad, I couldn't even open a photoshop file and save it out at a Tiff without it crashing. I noticed someone on this thread mentioned using Macs Fan Control. I downloaded that and noticed when using photoshop, even with the macbook feeling like it's getting warm, the fan speed wouldn't increase. I thought that was odd because when I use Final Cut X the fans go pretty much wide open.

So I noticed the crashing started happening in the 120F to 127F range on the GPU Diode sensor monitor on the Macs Fan Control app. Manually increasing the fan speed for both fans to around 4k RPM easily kept the GPU Diode temp below that even when running filters in the Photoshop Filters gallery and nothing I did would make it crash. I actually have the "Control" set on the Macs Fan Control app set to "Based on GPU Diode" now from the "Sensor-based value" radio button. I have the temp the fan speed starts set to 104F and the Max temp set to 118F. Now the fan speed acts very similar to how it does when running Final Cut Pro with when I'm doing saves/renders/ or filters, the fan speed ramps up to max as it gets to 120F range.

Then I dropped the fan speed (or set it to auto which the current fan speed would still hover around 2160) and tried to save out a Tiff file from Photoshop, the GPU got slightly over 120F and got the black screen crash with GPU panic error log again. I then went to bed and realized I'd solved the problem.

Today I was attempting to show my wife how it would do it as it heated up keeping the fan speeds low and got the GPU Diode up to 143F with it on my lap and it still didn't crash. This was pretty puzzling to me, but there's something to this fan speed issue. These Nvidia cards that do in app Cuda processing really get warm, and the fact the RPMs of the fan aren't jumping up automatically I think is the root of the issue. To me that sounds like a software issue, not a hardware issue.

This might be a very simple fix!

Serious shout-out to Simon for this find. My mid-2012 MB Pro Retina 15" running OS X 10.9.5 was having serious black-screen issues. It would crash sometimes, and other times seem to be running with no screen output. Every once in a while I was able to get it going, and eventually I got gfxCardStatus running on it. I set to Integrated Only, and like many others I was able to get it to run OK for a while, so long as I didn't log out, reboot, etc., since gfxCardStatus appears to be a per-user application, rather than a global application.

When I had it running, I tried Simon's fix, in particular:

Edit the cd /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphic s.framework/Resources/Configuration.plist and changed the 'ForceSessionDrawsVirtualFramebuffer' value to 'YES'

To do this, you'll need to enable the root user and edit the file somehow. I used "defaults" on the command line to do my editing. Something like this as root should hopefully work for you, but be careful when doing so and use at your own risk of course:

* defaults write /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics .framework/Resources/Configuration.plist ForceSessionDrawsVirtualFramebuffer -bool yes

After running this, as any user, you should be able to see this:

$ defaults read /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphic s.framework/Resources/Configuration.plist ForceSessionDrawsVirtualFramebuffer

1

The '1' here from the output is the key. After doing this, I have yet to experience significant problems. I can switch users with no issues, lock the screen, etc. It's only been a couple of hours but I'm very optimistic. The only issue I've had to far is that on reboot, I will sometimes (maybe frequently) get a black screen for a login, despite the fact that I can tell the computer is on since the keyboard is responsive. All I've had to do so far is close the screen, leave it closed for a bit, and open it back up -- works.

Perhaps most promising, if I launch gfxCardStatus from the command line, I see the following:

2014-11-22 16:22:03.244 gfxCardStatus[] [lvl=2] -[gfxCardStatusAppDelegate applicationDidFinishLaunching:] GPUs present: (

"Intel HD Graphics 4000"

)

2014-11-22 16:22:03.245 gfxCardStatus[] [lvl=2] -[gfxCardStatusAppDelegate applicationDidFinishLaunching:] Integrated GPU name: Intel HD Graphics 4000

2014-11-22 16:22:03.245 gfxCardStatus[] [lvl=2] -[gfxCardStatusAppDelegate applicationDidFinishLaunching:] Discrete GPU name: (null)

2014-11-22 16:22:03.260 gfxCardStatus[] [lvl=2] +[GSGPU is2010MacBookPro] Nuke it from orbit switching disabled.

2014-11-22 16:22:03.260 gfxCardStatus[] [lvl=2] -[GSMenuController updateMenu] Using dynamic switching?: 1

2014-11-22 16:22:03.260 gfxCardStatus[] [lvl=2] -[GSMenuController updateMenu] Using old-style switching policy?: 0

2014-11-22 16:22:03.261 gfxCardStatus[] [lvl=2] -[GSMenuController updateMenu] Intel HD Graphics 4000 in use. Sweet deal! More battery life.

I'm almost positive that prior to making this change, it reported both the Intel and the NVIDIA GPU's. Now, it seems to not see the Discrete GPU at all!

I have no clue what this option does, or why it seems to fix things. Maybe it's incompatible with the discrete GPU for some reason, and so the kernel switches the discrete GPU off. No matter, things are 95% better than the were prior to this change. If I didn't have to do this funny close/open trick, it'd be 100% better.

I think I could probably even shut off gfxCardStatus and everything would keep working, but for now I'm not going to risk it.

Important! As root, after doing the above call to "defaults", you probably also need to do:

$ chmod 644 /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics .framework/Resources/Configuration.plist

I'm curious if anyone has tried the above solution and if so, if it has worked for them.

I am now on my third logic board in two weeks. The second time around they also changed the top case/battery and replaced some cable from the HDD.

Four days in on my new logic board and I got my first graphics card related crash today(I had a separate wake from sleep crash earlier but I think that isn't related).

I hope Apple finds a better fix to this soon...

Just had my logic board changed on Sunday under European Consumer Law. It was ready an hour and a half after I dropped it off so I can't imagine the testing was exhaustive. I could probably try crashing it using GpuTest but I really don't want to poke the snake to see if it's dead. For now it's running without problems.

Having the same problem here; Macbook Pro Retina 15-inch, Mid 2012 2.3Ghz. Kernel panics and reboots, with blank screen, sometimes 4/5 times per day. I went to the Apple Store and The Genius offered me the substitution of the logic board because of a faulty GPU, with a cost of almost 500€ (easily a quarter of the total computer value) and I rejected arguing the computer was just two months after the warranty expiration date and the similarity with all the cases of kernel panics and reboots in the same model of computer that are shown, for example, on here. The Genius talked to me about a 6 month after warranty expiration date "courtesy" and after talking to a supervisor, they offered me a 25% discount in the reparation, which I was not satisfied with.

They told me about writing to Apple Feedback and also Apple Care to report all this cases and try to achieve a Substitution Program.

This is an example of a kernel panic log:

New logic board seems to have fixed mine. Been good for some weeks now

Got my logic board replaced as well last week and it seem to work properly as far as I can tell. The technician blamed some dust getting hot and burning some of the components. They charged me about $850. And before you get too upset, this is in Sweden, prices are usually higher here than in the US.

I believe I've gotten to the bottom of this. Using Cinebench's graphics benchmarking app, along with the iStat Pro widget and smcFanControl, I was able to determine that the issue is that the GPU is heating up, but the system is not kicking the fans on. When the GPU goes above 70ºC, the system shuts down to save the internal hardware, which could be damaged at temperatures exceeding 70ºC.

Therefore, the issue can only be one of two things:

1) A simple firmware issue. The temperatures of the GPU are not being taken into consideration for the fan speed, which is only adjusting for CPU use, and therefore a simple firmware update could take the GPU and CPU temperatures into consideration.

2) A hardware issue. The GPU is, for whatever reason, not reporting it's temperature to the system, and is overheating without warning the firmware to increase the fan speed.

I think the issue may be a bit of both. Some have fixed this issue by replacing the logic board, which could signal a hardware defect. Using smcFanControl, I was able to boost the fan speeds up to maximum manually and run my tests. I found that the system did not crash when I did this. I think the issue is that the hardware is not reporting the correct temperature, and therefore the best solution is to replace the logic board. If this is not an option, you can manually control the fan speed using an app like smcFanControl, but as this is an annoyance, I recommend the new logic board.

Hopefully Apple has seen enough of these cases to admit there is a serious problem with these graphics cards, and will replace your MacBook Pro's logic board for free. The repair is a bit of a pain, but in an Apple Store that isn't very busy, it should take less than a day, an hour or two, tops.

My Mid 2012 Mbpr 15 16gram 256ss I has suffered gpu issues. No apple care now 300$ to "fix" it with possible refurbed parts and 3 month coverage of "new" LB. Apple your not Walmart. Heck even GM has owned up th their faults! The thought I would shut off the discrete gpu on this is laughable, it's a designers machine. I do run a Thunderbolt Display regularly with latest Mavericks. Was too afraid of recent wifi reported issues as this laptop doesn't have a lan port So no jump to Yos. I bought this in hopes it would run when I needed it, well..... That day has come and my machine sits at the depot as o type this! Wow just wow. Btw 50% of our office macs have suffered this. were still counting!

same problem here, MacBook Pro (Retina, Mid 2012) logic board (SN: C2QKP009F9F2) purchased from apple (as refurbished) now gives me the very same kernel panic and it's nothing apple can do about it (because it's not a software related problem). the problem is with the gpu unit and can be reproduced (in both mac os x AND windows / under bootcamp) very easy. download and run the following (cross platform) application http://www.Geeks3D.com/GpuTest/ and run it for 2-3 minutes in full screen mode (the GPU temperature will be around 90 celsius), when it comes back from the stress test, it always happens. and it is not from switching between discreet graphic (NV650) to Intel HD Graphics 4000. Even if you enforce it to stay in NVidia mode, it still happens. i mention that this was NOT happening before (only macbook pro(s) older than two years get that, how, beats me). There is a cure, if you do not need the graphic intensive functionality, use gfxCardStatus and force it to Integrated Only (you have to select this option twice in order to have it enabled). Of course, in this mode you cannot use multiple displays (via thunderbolt) which defies the purpose of using this inferior machine for development. since i do not have apple care coverage for this machine, most likely, a mother board replacement would be way over $1000. i do believe that apple should have recalls, but then again, who cares (with the money from a mother board replacement one can buy a lenovo w540 which is a superior machine, btw, lenovo used to have similar problems and DID issue post warranty recalls at no cost!). after all it is not apple's fault that i am their customer, but rather mine. do not worry apple, it will never happen again (same about development subscriptions, mobile devices, mac pro, apple tv, etc). good night apple.
