    Hello everyone,

    I would like to post my experiences using two identical macbook pros 2012 (non-retina, with nVidia GT650M 512MB) who presented the same graphics cards glitches and problems, and hopefully to obtain some information.

    Exhibit 1: My own macbook pro

    Bought from France, in November 2012. Used mainly for professional non-graphics programming, it's clean, no bloated software, and only necessary professional tools are installed. 16Gbytes of memory, by Crucial.

    At some point during July, when the machine was relatively cold and I was watching a youtube video, this happened (see attached pics). The mouse was moving, and the computer was fully operational, but with this "glitchy graphics overlay". I logged out, and logged back in. Problem disappeared and appeared again at random times, 4 times during an hour. All those times, a log-out and log-in would fix the problem. After that, I could not reproduce it. Apple changed the motherboard, claiming that it could be a faulty nVidia card.

    Exhibit 2: My brother's macbook pro

    Bought from Greece, in february 2013. Same model as my own, same RAM, same specs. Used for professional video editing, no bloated software, mostly using Final Cut Pro X. He noticed various malfunctions with FCPX, like freezing when applying a visual effect, and graphics tearing when rendering (that's when the nVidia card kicks in, normally). Yesterday, same symptoms as my macbook pro appeared, graphics tearing, etc.

    EDIT: videos of the problem:

    Both machines are in a completely different environment (I live in France, my brother in Greece), non-smoking areas, and have worked in completely different ways. Both with OS X 10.8.4.

    That's two out of two. Given nVidia's background, I am starting to feel that my purchase is not so reliable as I originally thought, and I am thinking that this problem is more generic than originally seemed.

    Does anyone have any relevant information on this matter?

    Ça doit être des MBPs jumeaux... Ya de la télépathie dans la souffrance aussi... :D

    [MOD NOTE]
    Translation from translate.google.com:
    It must be twins MBPs ... Telepathy are in pain too.

    Difficult for this to happen since they were manufactured in different months.

    BTW, it would be helpful for everyone in this forum if we could stick to english ;)

    Interesting. No issues here.

    However, this is why tomorrow I'm buying applecare for my MBP.

    The only thing in common are that these MBPs were purchased in Europe.

    I am pretty sure the problem was OS related. I've had issues in the past where the latest mac os updates are somehow not optimized at their best, which is really likely to be giving you these glitches.
    This particular model (mid 2012 non retina) isn't affected by this: https://www.apple.com/support/macbookpro-videoissues/.
    It can't be the video chip. Let alone the fact that 2 out of 2 machines in your life have failed in the same way.. Im guessing that the mac os version wasn't right at the time, plus.. both laptops were on 10.8.4.
