Alright Mac gurus, I've got one for you.
My inquiry involves my mid 2012 15-inch MacBook Pro with Retina Display and its frequent, inconsistent kernel panics, which started occurring shortly before Mavericks launched (which I hope rules out anything OS specific). For the record, I have brought it to the Apple Store twice, the second time of which they ran one of their "extensive" tests on it overnight only to find nothing wrong with it.
I am about to bring it in again, but before I do, I thought I might try to use this ordeal as a learning experience, as I am quite intrigued with the nature and persistence of the issue, so I thought I might ask the community. I have done quite a bit of research, and can say that I have a basic understanding of what a kernal panic is and what some of the primary causes are. I am slowly moving through all the different troubleshooting methods, but this is a slow process because, again, the panics themselves are seemingly random. While I understand that the majority of panics are software related (caused by a troublesome third-party driver), I am being led to the conclusion that the issue might be hardware related. Though I won't go into extreme detail, here is a quick list of all the main trouble shooting methods I've done:

It's always a "GPU panic" and from the list of kexts, it's never constantly one particular kext that is the last to be loaded or unloaded. Is it possible to discern if it's hardware related from a crash log, and if so, why wouldn't the computer report the issue (which seems to be GPU related) when we ran Apple's hardware test on it at the Genius Bar?
I recognize that this might be a complex issue that simply can't be diagnosed by any crash report, so I'm okay with hearing that answer if it's the case. I also accept the fact that understanding how to read a crash report might simply require a much deeper knowledge of UNIX than I have. I thought I just might try to learn as much as I could and then share it with others who might have the same problem. Any help you guys could give would be super-appreciated. Thanks!
My inquiry involves my mid 2012 15-inch MacBook Pro with Retina Display and its frequent, inconsistent kernel panics, which started occurring shortly before Mavericks launched (which I hope rules out anything OS specific). For the record, I have brought it to the Apple Store twice, the second time of which they ran one of their "extensive" tests on it overnight only to find nothing wrong with it.
I am about to bring it in again, but before I do, I thought I might try to use this ordeal as a learning experience, as I am quite intrigued with the nature and persistence of the issue, so I thought I might ask the community. I have done quite a bit of research, and can say that I have a basic understanding of what a kernal panic is and what some of the primary causes are. I am slowly moving through all the different troubleshooting methods, but this is a slow process because, again, the panics themselves are seemingly random. While I understand that the majority of panics are software related (caused by a troublesome third-party driver), I am being led to the conclusion that the issue might be hardware related. Though I won't go into extreme detail, here is a quick list of all the main trouble shooting methods I've done:
- Reformatted and reinstalled OS X completely multiple times (10.8 and 10.9), and started fresh (no Time Machine Backups).
- Reset PRAM
- Moving through 3rd party drivers I do use, of which there are not many. I've already ruled out a few by experiencing a crash while the driver wasn't installed.
- Removed all external peripherals (and have had panics during those times)
- Booted in Safe Mode (and experienced a crash)

It's always a "GPU panic" and from the list of kexts, it's never constantly one particular kext that is the last to be loaded or unloaded. Is it possible to discern if it's hardware related from a crash log, and if so, why wouldn't the computer report the issue (which seems to be GPU related) when we ran Apple's hardware test on it at the Genius Bar?
I recognize that this might be a complex issue that simply can't be diagnosed by any crash report, so I'm okay with hearing that answer if it's the case. I also accept the fact that understanding how to read a crash report might simply require a much deeper knowledge of UNIX than I have. I thought I just might try to learn as much as I could and then share it with others who might have the same problem. Any help you guys could give would be super-appreciated. Thanks!
