    My Mac is just turning off, well the screen mostly even connected to an external device sometimes restarts itself.
    Fans have been going mental for months as well.

    I've copied in the error report below along with its spec, is there anything i can do to fix this?

    I can access the computer via share screen but nothing else.

    Is it a genius bar and graphics replacement job and if so is it really worth it on a almost 6year old computer?


    MacBook Pro "Core i7" 2.3 15" Retina 2012
    Graphics Inter HD Graphics 4000

    Take it in and see what they say. But, It is hard to justify spending a lot of money on the system.

    It looks like a GPU issue but the "etc etc etc" could contain important information.

    Your model had a "Repair Extension Program for Video Issues." The program has ended but you may want to contact Apple to see if they can run the diagnostic test mentioned in the below link on your MBP. If you can get them to run the program and it turns out that it's not the GPU, then the kernel panic report may have important information as I mentioned. You can try running the computer in safe mode as the computer will not load 3rd-party kernel extensions, etc. that are the cause of most non-hardware related kernel panics. If it works in safe mode when it didn't before, you have a software issue.

    If it is the GPU then you should get quotes from Apple-authorized service providers as they would likely quote a lower price. But GPU repairs that Apple did for the 2011 model typically failed later - I don't know if the same is true of the 2012 GPU issues.

    Sorry i just didn't want a big scroll, here is the rest...

    --- Post Merged, Jan 31, 2018 ---
    I’ve managed to start up in safe mode and it seems a little more stable, but saying that a normal start up sometimes works. Is there anyway within Safe Mode to determine if anything is effected?

    Also if safe mode does seem to be okay how do i go about isolating the problem, a resin tall of Sierra with a time machine backup or something else?

    I only have one login item within login items and thats mail.

    One observation is that the fans are not going crazy in safe mode which they’ve been doing for months!

    In the kernel panic report, there are no 3rd-party kernel extensions in the backtrace so it's more likely than not the GPU issue which prompted the warranty extension program is the cause of that specific kernel panic than any software issue. So, I think a visit to the genius bar is a good idea. Ask them if they can run the diagnostic program for the 2012 15" Retina GPU issues. If I recall correctly there was at least one person here in this forum who reported that the diagnostic program said their MBP didn't qualify for the repair (when it was active) but who really believed that the GPU was faulty.

    A program like EtreCheck will help to identify the startup items, launch agents, launch daemons, user login items, plug-ins that run without the user explicitly starting an app. Any of these items may cause issues and one of these may be causing the fan issue. You can use the "Activity Monitor" app to see which process is using the CPU - which in turn is the likely cause of the fan running so much. If you find a suspect item, you'd have to deactivate or de-install it and see if it changes anything.

    Would a fresh reinstall also fix these problems if it is indeed a software issue?
    As safe mode seems okay, i assume a fresh install of Sierra also works in that way, otherwise the screen would go off during that process?

    Might try that before a genius visit...

    Give it a try but its sounding like a dgpu issue to be honest. The kernel extensions that deal with your dgpu are almost certainly turned off in safe mode but I have been unable to clarify that.

    A fresh install would likely solve your high CPU usage. You would then add your additional software one-by-one, making sure you have versions compatible with High Sierra and either deciding to drop an app if it causes issues or trying to troubleshoot it. It may also be that the high CPU usage exacerbates a possible GPU problem.

    However, it likely won't solve the root cause of whatever caused your kernel panic. I did have an issue once with my 2012 Mini and Yosemite versions later than 10.10.2 which caused GPU (for the Mini it's a iGPU, not a dGPU) kernel panics - which stopped once I installed El Capitan - and maybe, if you your problems only occurred after you installed High Sierra, reverting back may help. But I don't think this is the case with your MBP as Apple acknowledges there were GPU issues with at least some of the 2012 15" retina MBP's.

    I did find this article on the web which looks to involve the 2014 MBP's with the NVidia GPU and the kernel panic report looks similar to what you have. There aren't that many people (if any?) on this forum with the 2014 MBP who has the same issue so I don't know what to make of it.

    So I think you should take a trip to the Genius Bar, if not overly inconvenient to see what they have to say.

    Reinstalled and still happening.

    Now need to decide whether to pay them to check.

    Its going to be a few hundred to sort i think and is it worth it on an almost 6ry old computer?

    It would not be worth it to me. But, only can decide if it is worth it to you. Personally, with a system that old my thought would be "what will break next?"

    A visit to the Genius Bar would be free. If it is the GPU, Apple would usually replace the whole logic board and one post says Apple quoted $575 (as of Jan. 26, 2018) for this. I haven't seen a definitive explanation of the 2012 issue but with the earlier MBP's with dGPU issues the problem was with the solder used to attach the dGPU to the logic board and more often than not the replacement ended up failing again down the road.

    If your MBP is in otherwise good shape and if it is the GPU issue, if it were me, I would sell the MBP (parts are worth something) and get an Apple-refurbished 2015 15" MBP - they have those for $1700 with 16GB of memory vs. 8GB you have now with the same size SSD (but significantly faster). If you still have the original battery, the cost of Apple replacing it is $199 so you could count that cost as part of keeping the 2012 MBP. At one point, people were able to get a newer model if the battery needed service - this situation has been fluid and I think I saw somewhere that this was no longer being done.

    EDIT: If you do get a replacement MBP 2016 or later, you're going to have to spend extra to be able to connect your LaCie d2 as there are no Thunderbolt 1/2 ports on the MBP >= 2016.

    The keyword to use at the Apple Store is satisfaction. If you're told about the repair plan being over you can say something along the lines of it not being a satisfactory state of affairs for a computer that you expect to last 6 years. It might be worth phoning Apple support and running it by them to see if you can get some sort of satisfaction code to take to the Apple Store - it's like giving the Genius folks more wiggle room to go through the expense to repair - or do some sort of deal like give you a sizeable discount off a new replacement (this is just fishing at this point though).

    At that age, yes, paying money to repair a 2012 might be a false economy depending on your budget and getting a newer model might be feasible if you can afford that instead. You've had more than your money's worth from the 2012 model and there's plenty of deals from retailers for newer models from time to time.
