5K turns off sometimes on its own?

    Sometimes after not using my 5K for a day or two I come back to it and it seems to have turned it self off. Is this a common problem? Any ideas of what might be wrong?

    You set your iMac never off / sleep?

    And do you have a reliable power source?

    It's quite unusual the Mac turn itself off. For hardware failure (except overheat, which should not happen at idle), the Mac usually hang / restart but not self shutdown.

    No, I can't say that this ever occurred on my iMac

    Same thing happens to me. I'll put my iMac to sleep and return a few hours later to find it off. After turning it back on, I'm always greeted by a lovely "Sleep/Wake Crashed" message. But it seems to be resolved with the new 10.11.6 Beta
