What is Causing the Kernel Panic

macos kernel-panic

I've been having an issue where my computer will randomly shut down and give me the panic report saying that your computer restarted because of a problem. I took it to the apple store they ran a diagnostic, and all they did was wipe my OS. It is still having the same problem so I recently just erased my whole system in reinstalled my OS X 2 more times, and I still seem to be having the issue. I have reset the smc and nvram multiple times. I've ran the disk utility first aid multiple times. Can some interpret this for me who knows how to read panic reports to see what is causing this issue.

Crash Log 3 (I edited this out - it was the same as crash 2 - you can see the system uptime in nanoseconds for a quick check before pasting in the third :-)

The hardware is a retina 2012 MacBook Pro and has all software updates and EFI updates applied.


Please keep in mind this is a guess, based on the 3 logs you provided and your description that you've wiped the OS several times without a change in issue behavior.

I noticed that all 3 logs show a crash when loading the same kext:

last loaded kext at 7766792260: com.apple.driver.AudioAUUC  1.70 (addr 0xffffff7fb02f4000, size 32768)

This may indicate an issue with audio from your motherboard, assuming your not using any external audio interface. Another potential cause is an issue with RAM.

The machine certainly seems to have a hardware issue of some sort. A practial solution for most HW techs at this point, would be to install test RAM in the machine and run the machine through its paces to see if the issue can be reproduced. Depending on the frequency of crashes this can take a few hours, or days. Since your RAM is soldered on the logic board, that would be swapped in case of a RAM issue.
