I am a total newbie here, so I truly hoping someone can help me. I have a late 2012, 21" iMac running Sierra. I keep everything updated. For the past few months, I have been getting kernel panics, two and three times a day. Sometimes it happens when it wakes up, but other times, just during ordinary use.

This is the latest report it gave me: (I just have no idea what any of this means, so I am desperate for your help!)

Sadly, I tried those. I reset the PRAM, repaired the drive, and even reinstalled the MacOS. I did not do a clean install, though. Seemed OK for a day or so, but it started up again. I do have everything backed up, but I don't want to have to go through a clean install, and reinstall my life back on it. I will, of course, do that if I had to. (I really appreciate your help!!!)

Have you run Disk Utility-First Aid? Do that. My 50-50 hunch is the drive/volume are at the root of this. If you can, boot into a recovery partition, and run Repair Disk from there.

Do you get the kernel panics if you boot from an external drive?
My main drive is an external SSD (Samsung 850, 1TB). I updated to that about a year ago. No issues that I know of, but I ran the Disk Utility, First Aid from the recovery partition as Kohlson recommended. I will see if maybe that helped... I had run it previously in safe mode with no change, but not from the recovery partition. Fingers crossed! Any other suggestions would be greatly appreciated, but I will update this, once I see more. Thanks in advance!

Awful lot of power being drawn if the majority of all those hubs are bus powered. Suggest booting with just keyboard and mouse and see if the kp strikes. If not, add the additional one at a time and see when/if thekpcuts in.

Is the external boot drive plugged into a hub, or is it plugged DIRECTLY into one of the ports on the iMac?

If it's on a hub, plug it directly into the iMac.
REMOVE any external hubs currently conneted.

Try booting up again.
Any changes?
Does it run smoothly that way?
If so, CONTINUE to run it that way for 48 hours.
Still stable?

If so, that should tell you something...

Check your kernel extensions. Often times the last loaded kext is the cause of the problem. In your case, that would be com.parallels.kext.vnic. Try updating your Parallels or uninstalling it and see if that helps?

Good idea to make sure the rest of your third party kexts are all up to date:

This part makes me think you may have a failed GPU.

Just as a test, try a safe mode boot to stop the Parallels kext from running. Like @Silencio mentioned, sometimes that last loaded kext is a big clue.

I have had a couple of Macs in the past that have suffered from Kernel Panics. With some machines it has been USB hubs, especially when waking from sleep. I have fixed problems by trying different USB hubs. Some USB drives also seem to be a problem, I have one drive that prevents my Mac Mini from booting but works when plugged in later.

With a couple of machines it has been the memory modules. I have sometimes cured problems just by pulling out the memory and slotting it back in. Sometimes I take out one module and see if it makes the machine more reliable. My current Mac Mini kept on locking up, but when I replaced the two 4GB sticks with one 8GB stick the problem went away.

Is that relevant at all or is it just one of the storage volumes?
No... I read this long ago and can't seem to find the link now. But what I recall is when a crash happens, you can optionally send that report to Apple. And that UUID identifies your Mac without saying who you are. So for example, by checking those UUIDs Apple could see that the same types of reports are coming in from say 2012 27" iMacs and use that info to fix the issue.

I wish I could find you the article, but I'm having no luck.
