    It is true one should be careful about downloading software from unknown sties.  However is a well know site and gfxstatus is routinely used on Macs.  In this particular case it could be the key to stabilizing your system.  It would allow you to the GPU on and off so you use it only when needed.  With it off I believe you will be able to render all scenes but at slower speeds.


    Downloading to ML involves creating a clone backup of Mavericks, reformatting (and erasing) your system disk, installing ML and then manually reloading your data from the cloned disk.  It is a big step:  How to revert OS X back from Mavericks: .


    So, as I mentioned, I would test installing ML in an external disk partition before I made the switch to ML.  It has a chance of solving the problem but only a chance.  I would also exhaust the other simpler tricks before testing ML on an external partition.  If you get to the point of testing ML on your external drive, I believe it can be partitioned as needed without touching the data already backed up on it.  Post back for those details.

    Thank you.

    Now I'm trying to figure out when this problem appears and I have found the way to cause it: open hd video in VLC on Desktop 1 and on Desktop 2 I'm trying to playback 1080p video from youtube. It takes about 1 minute for screen to become black.


    And here's log that I have now:

    Great work!  There is an old adage that if it ain’t broke you can’t fix it.  Now that you can break it at will so you will be able to test the workarounds and maybe avoid it just by managing what you run when and how.

  • Tema Krukovets Level 1 Level 1 (0 points)

    Anyway what can you suggest me in that situation: my warranty ended at 29th of December and this problem appeared only now, but it looks like now my fault, so is it possible to ask Apple to repair my MBP ?

  • hands4 Level 4 Level 4 (2,220 points)

    Yes, but it will be expensive.  You'll have to talk to Apple for a quote.  This is why I'm looking for workarounds so you can live with the hardware issue as-is.


    The three pending workarounds are:


    - Disabling automatic graphics switching.

              An easy test.


    - Using gfxstatus and set the video to Intel.

              Try this and see how much it effects your programs that use the GPU.


    - Downgrading the OS to the previous version installed (Mountain Lion).

              - More work to test (install in a partition on an external drive)

                and even more work to implement

                but worth a try if nothing else has worked.


    These are now easier to test since you can break it at will.

  • Tema Krukovets Level 1 Level 1 (0 points)

    Thank you! I tried to disable automatic graphcis switching (as I understood, if I do so NVIDIA GPU will work all the time).

    So I started to watch 1080p at youtube and everything was fine, but when I tried to go to dashboard (sliding with four fingers) my screen became black and it takes me five attemps to boot MBP after that. One more strang thing: before my screen turned off it was a scratchy sound from speakers, I mean, sound twitching.



    BTW, could you provide me some instructions about installing ML on extarnal disk. Actually I have 32Gb flash drive. Is it possible to use it for loading in ML ?

  • Tema Krukovets Level 1 Level 1 (0 points)

    One interesting thing: today I continued testing this issue, I connected my MBP to TV with HDMI cable, run HD video in VLC and left it. Surprisingly, everything was good: video was played without any crashes. BTW, It was using NVIDIA card to play it. So, this issue is very strange...


    Actually, I don't know why Apple didn't left any comment about it, cause a lot of people have this problem with mid-2012 MBP Retina.

  • hands4 Level 4 Level 4 (2,220 points)

    Great to hear you are finding workarounds for simi-stable paths that are stable enough so you can get by.  Happy computing.

  • cscholz83 Level 1 Level 1 (0 points)

    Hello Tema: I started to get the same "GPU Panic" message yersterday on my MacBook Pro 15'' Retina mid 2012 and as with you Warraty expired on November 20th. Were you able to solve the problem?

  • 8thSage Level 1 Level 1 (0 points)

    Can I add a "me too" to this issue.  Same Model, Mac Book Pro 15" Retina Mid 2012 is randomly failing with a GPU Panic.  This started on the 30th of April.

  • cscholz83 Level 1 Level 1 (0 points)

    I had it working for a full day (Photoshop and Archicad) over a cooling pad and made a backup of all the system, it didn't crash at all so probably fans aren't working properly. Today I'll send it to Apple Service, will have answer maybe thursday. Any news will share it here.

  • CeesBerrens Level 1 Level 1 (0 points)

    You can add "me too" to this issue.  Model Mac Book Pro 15" Retina Mid 2012 is randomly crashing with a GPU Panic.  This started on the 14th of May. I disabled automatic switching. I hope this helps!!!!

  • cscholz83 Level 1 Level 1 (0 points)

    Hello CeesBarrens!!!


    On friday I got back my MBP 15'' Retina Mid 2012 from Apple Service, according to them HARDWARE of my machine is in proper condition but something with OSX was malfunctioning, they run APPLE test MRI and SD so they reinstalled it and restablish SMC and PRAM. They run the test again and for them everything was OK. Today  I got the GPU Panic my best guess is that's something wrong with MAVERICS!!! Tomorrow I will go to apple again and complain!! will let you know


    greetings from Chile

  • kennymitsu Level 1 Level 1 (0 points)

    WORKAROUND: I managed to solve the issue by turning off Automatic Graphic Switching found under: System Preferences > Energy Saver > Automatic Graphics Switching.


    Fingers crossed, it's been two days without a random reboot. Bit of a pain that the battery is going to suffer, but I can now turn on other power saving options that I had turned off whilst trouble shooting.

  • CeesBerrens Level 1 Level 1 (0 points)

    This worked for me as well Kenny. Please follow this post for my full report
