    Hello!

    I've encountered a strange problem over the last months with my iMac late 2012.

    Sometimes its freezes at the booting screen, with error codes and text lines. I attach a photo of it.

    A restart can fix the problem and the iMac will run fine as it ever did with no issues.

    But eventually the panic boot screen may represent very oddly and rarely over time. I think it happened two or three times in the last couple of months.

    Can someone help me? Maybe its the ram?


    Specs:
    iMac late 2012, 8 gb Ram, Core i7 3.1, Nvidia 650M, Fusion Drive 1 tb.
    MacOs 10.12.5

    Its a bit hard to tell from the panic. You would need to verbose boot before the machine panics to see at what point the panic occurs. My guess is you have OS issues. Symbolicating the panic isn't that useful. It would also be worth checking if you have any third party kernel extension installed.

    If the panic is intermittent, then I would do an over-install of the OS, and see if the issue goes away.

    Cheers

    You don't need to format, just reinstall the OS.
