2012 Pro Retina (15") Kernel Panic Problem

[mac_man_fran]

Hello all,

Hoping to get a little guidance on an issue I'm having. My 2012 macbook pro retina 15 inch is consistently having a Kernel Panic after being left idle for an hour. It seems to work just fine other than that and there are no performance issues that I am noticing. It only happens when I leave the display up and I walk away so I suppose I could just shut the display to mitigate the issue. But the thought that I might be working on a project and forget to shut it then return to have lost all my work is frightening. I'm really hoping to wait on the 2019 or 2020 macbook pro's before upgrading as I am hoping the next generation/design changes up the keyboard design into something a little more user friendly. I brought it into apple last week and they reinstalled OSX (latest version of Mojave). It was fine for a day or two but then the problem started happening again. I'll post the error below. It seems to be suggesting some issue with the GPU but who knows.

Search for "macbook pro video issues"
You will see quite a few links for that, which was related to a bad design - which Apple apparently did not choose to modify. You get visible graphics issues, or sudden restarts, or crashes. There were a variety of symptoms, all related to the graphics chip
Apple did have a repair program for 2011 to 2013 MacBook Pros, but that has expired, and even the support articles seems to have disappeared now. But, the "repair" program simply replaced the logic board with a "repaired" logic board, with the same graphics chip. The same graphics chip means that the problem will likely happen again.
But, here's one "fix" http://www.tomsguide.com/faq/id-3678804/fix-macbook-pro-graphics-card-issues.html

It looks like a GPU Panic, a known problem with the NVIDIA GeForce GT 650M dGPU on your model.

I remember when MBP users complained about the buggy GeForce chips. I just checked, and my 15-inch mid-2012 MBP has the Intel HD Graphics 4000 1536 MB chip installed. Thankfully I have no issues.

Disconnect all external devices and try again

Thanks for the responses everyone. Sucks that this is a known issue and it appears that the free repair period is over. The thought of buying a new machine for $2,000+ sucks but I need a reliable computer (starting law school in the near future). I already spent $300 on a different logic board issue with this computer and at this point, I don't think it is worth sinking more money into it. Might have found a decent deal on a brand new 2017 retina. My concern is how the keyboard on these new pro's will do long term.

I did. Only had an SD card connected. Problem repeated.

 

[Ruskes]

SD or SSD ?
what is it for ?
Since you have Windows on that system, can you boot in to it ?

Not sure what you mean. I'm not using windows. I had a Secure Disk card installed like what we use for cameras.

For now take the SD card out

Re-Read your OP again. It happens after standby mode
Lets test that
In Terminal app (utility folder) type this

pmset -g assertions

report it here

At this moment I do not think it is your GPU hardware, but a image that is trying to load after wake up

The info I posted above is without the SD card installed. I can try what you are saying in terminal app. I have to give it time to reset however so I will report later.

Check again!
Your mid-2012, 15-inch MBPro has two graphics chips. The Intel HD Graphics 4000, and an NVIDIA GForce GT 650M.
The 13-inch of that era has just the integrated graphics, but all 15-inch MBPros from that time have both chips.
(You have good luck, so far!)

Sadly, mine has the two chips. Still trying a couple of things out but looks like I'm going to unfortunately have to get rid of an otherwise perfectly good computer.

Had a similar issue, and temprarily fixed it myself until I had access to soldering equipment, it's been running fine ever since.

Check again!
Your mid-2012, 15-inch MBPro has two graphics chips. The Intel HD Graphics 4000, and an NVIDIA GForce GT 650M.
The 13-inch of that era has just the integrated graphics, but all 15-inch MBPros from that time have both chips.
(You have good luck, so far!)

You're right. It does have the NVIDIA GeForce GT 650M and the Intel.

The most likely cause for a Kernel Panic issue in macOS is faulty software, damaged or incompatible hardware, including external drives attached to the Mac. To fix the issue, try the below steps:

1. Restart your Mac in Safe Mode and check for updates.
2. Uninstall any plug-ins or 3rd party software from manufacturers other than Apple.
3. Disconnect all connected devices.
4. Use Apple diagnostics to diagnose the problem.
5. Reset PRAM/NVRAM settings
6. Reset SMC (System Management Controller) settings
7. Reset the GPU (Graphics Processing Unit)

Hope it helps!
