    I purchased a 2012 retina MacBook off craigslist, while I was purchasing I went to reset it and it hung up on the black screen, he hard reset it after about 30 secs and said thats what you have to do sometimes, for some reason I still bought the damn MacBook lol. anyways I get to my studio and don't use it much that night, besides to play around with the programs that came on the computer (about 30 mins ). next day I hook up my clarett thunderbolt interface I've been DIEING to use, I bought this computer to specifically use that interface.(couldn't use it the first night, did not have a thunderbolt cable and Frys was closed.) so I download the drivers for the Mac and install them, everything goes smooth until the refresh for the install of the drivers, thats when it gets stuck on the black screen for the reboot. I hard reset and get my first gpu panic...... now I'm starting to worry a bit but I super excited to use my new gear so I proceed too open up Logic Pro x and enable the clarett, wow this interface puts out such a clean sound, I'm quite happy with it. so I start messing around in logic and about 5 minutes go buy and a black screen with a quick flash happens. now the computer turns on to a completly black screen and won't boot, but I figured out if I power up the machine, shut the screen 3/4 down , it will boot.
    here is the report
    thanks in advance

    Your machine most likely a gpu problem. Is your machine a 2011 i7 model or are you sure it is 2012? If it is a 2011 i7 then you have a major problem. How much did you pay for it?

    The 2012 MacBook Pro Retina is also affected and included in the repair extension program

    Obviously, the problem doesn't occur as often on the 2012 Retina, but it's still a known problem.

    im 100 percent positive its a MacBook 2012 retina display model. I paid 800 dollars cash for it, its a big hit for me but a major upgrade for my recording setup if I can get the machine to work within the repair extension program. I entered the serial of my Mac and it says validated purchase but warranty is not covered anymore. not sure what the validated purchase means but its a green check so I'm hoping that means it was purchased within that 4 year span of replacement . they stop the repair service in 2016 of December so idk. thats if it is the video card, any clues from the gpu panic?
  5. tubeexperience macrumors 68040

    Validated purchase just means that it's a genuine Apple product and Apple has the serial number in its database.

    "The program covers affected MacBook Pro models until December 31, 2016 or four years from its original date of sale, whichever provides longer coverage for you."

    Seriously, you need to read AGAIN

    I don't have any original receipts or original proof of purchase, wouldn't you need that for the coverage? I scheduled a appointment with apple tomorrow so hopefully that clears up some questions.
  7. tubeexperience macrumors 68040

    Feb 17, 2016
    Nope. When the computer gets set-up for the first time, it would connect to Apple's server and that's the day that Apple counts as the first day of warranty coverage.

    okay, so I won't know until tomorrow then or is there a way for me to find this information

    Why would you buy a laptop that had issues from the get go?
  10. future-trunks thread starter macrumors newbie

    Jun 11, 2018
    the seller said it didn't have issues, and is a tech. but yes, when he had to hard reset I should of known not to buy it. I also didn't know about the recall on the video card, he did mention the gpu overheating issues of the older MacBooks. but I bought it because I thought I was getting a good Mac book for a reasonable price. so yeah, I messed up and made a mistake, now I'm just trying to find out whats wrong with it because he states that it preformed well for the time he has had it. wich I find hard to believe when all of these problems are occurring on this machine

    Its broken :( If you want to know more, let Apple or a third-party service provider make a diagnostics for you. You can also try running the hardware diagnostics yourself. Anyway, symptoms you describe sound like logic board replacement. Sorry man, its annoying :(

    Apple will run the Mac Resource Inspector tool, which looks like this:


    After that, Apple will run Video System Test (VST), which looks like this:


    It will determine whether or not the dGPU has failed.

    You could try using something like to force your laptop to use the Intel GPU instead, will slow it down for graphic intensive apps. But if you do have an Nvidia GPU issue, should at least mean you can use the laptop.

    You could also try installing the Nvidia GPU drivers from

    If the laptop is in good condition [ie. no dent (scratches are okay)], you ask for a $300 deport repair.

    Apple won't tell you about this: you will have to ask about it.

    I dont think it is a secret, genius bar will suggest this for out of warranty repairs that they can't do inhouse.

    Canada Eh?
    It isn’t the GPU. It is the GMUX chip. They have bad solder joints on the 2012 retinas. It is a 28 pin QFN package and just needs to be resoldered by someone with a good soldering setup. The chip designator is U8900if they have a board view of the logic board.
  17. future-trunks thread starter macrumors newbie

    Jun 11, 2018
    sounds like it could be a loose solder joint. took it to apple and the ran it through the diagnostic test and it came up fine, the guy was puzzled why the MacBook wouldn't turn on as well. I demonstrated the trick to power it up with the lid almost fully shut and it booted up, a couple of attempts of course. video card was fine so he suspected it could be a logic board maybe but he really didn't know since the test that were ran all came back fine. it has had a upgraded ssd/flash memory, so its been modified. it also has a 2014 bottom cover plate on so the computer rocks backs and fourth, it dosent lay completely flat, this was the first thing he noticed. it dosent fit because theres four magnets that snap into place on the 2014 model and you can see them pertuding out from the case, he also said there located directly on the battery and hd. all in all they said for 570.00 they will rebuild and replace anything that is damaged, I don't know if thats a regular rate for fixing the Mac book or if thats under a warranty. I fort got to mention the depot repair. honestly if the craigslist seller gives me back half of my cash or at least pays for half of what it cost for apple to rebuild it, I would be happy. what are your guys thoughts?

    If the Macbook were being repaired under warranty, there would be no cost. This sounds like an out-of-warranty repair with a 90 day warranty.

    Have you discussed the matter of a refund or partial refund with the seller?
  19. future-trunks thread starter macrumors newbie

    Jun 11, 2018
    Not yet, I told him the problems I was having with the mac book, and declared i want the MacBook fixed or refunded my money. He said the mac book had no issues when he sold it too me, he also couldent awnser why he had to hard reset it. Then he said i accused him of selling me a bad unit when all I replied with was the problems that occured 45 minutes into using the machine, the hang ups on restart and now the boot to black screen. I simply described the issues and stated I would like the machine fixed or a refund.he then went and said if I keep acusing him he would not reply to me till the weekend. I just told him reread my texts, I never accused you I stated what was wrong with the computer within the first 45 minutes of use, and would like a refund or it fixed and what is happing is no where near normal. Ill text him later this week when hes "back in town". I really hope he will help me pay to get this MacBook fixed or refund my money so I can buy a refuebished machine, unless thats a bad idea aswell

    A refurbished machine directly from Apple will be fine. A refurb from another retailer may not be so good if it doesn't carry the standard Apple 1 year warranty.

    I would not expect the seller to make any offer of a full or partial refund.
  21. future-trunks thread starter macrumors newbie

    Jun 11, 2018
    Yeah, I'm deffintly not expecting him to either. But hey, it would be nice to know theres stand up people out there. He seemed like a real nice dude who knew alot about macs. Olny time will tell now. And if i have apple fix it you say its warranty last for 90 days? Even if I soldered the jointa IF they were the culprit i still need a new bottom plate cover so my internals wont be damaged and the computer will sit flat lol. It is all my fault I'm in thia position and i k kw i made a mistake not meeting with the seller at a apple store. Tsk tsk

    I'm surprised Apple offered to fix it for $570 since that MBP reached legacy status a while ago and I didn't think the logic board was still available.

    If Apple does what they did with the 2011 15" MBPs, they will replace the logic board with an identical board that has the same inherent problem as the board that is currently in your MBP.

    Jun 11, 2018
    O man, your kidding right. I cant win in this situation huh, ive been trying to look at the bright side but it seems there is none besides "learning from my 800 dollar mistake". And why would apple replace it with another faulty logic board. I dont even know if thats the problem, could be loose solder joints or the machine could have been dropped and internals were banged loose. I dont know why the bottom plate would be replace unless it wad heavily damaged from a drop or bend. The battery has also been pryed up aswell

    The 2012 models are still supported ... even the unibody ones.

    They won’t be supported for much longer though. Personally, I’m expecting them to be given vintage status sometime this fall, or winter/spring at the latest. I plan on getting a new battery from Apple for my unibody mid2012 15” soon, before support is dropped.
