Constant kernel panics after macOS High Sierra upgrade

I have a MacBook Pro (Retina, 13-inch, Late 2013, 250 GB SSD, 16 GB RAM). I have experienced constant kernel panics after macOS High Sierra upgrade, from Sierra. (Under Sierra 10.12.5 the Mac was as stable as one would expect.)


In High Sierra the OS would boot and almost immediately go into kernel panic. I reinstalled the OS from OS X Recovery (having run Disk First Aid, which revealed no problem) and it worked OK for a couple of days.


I restarted (having noticed an odd behaviour in Contacts) and the problem recurred. Again I had a kernel panics 60-120 seconds after restart, or immediately the Finder started to load.


I again reinstalled the OS from OS X Recovery but the panics continued. I ran Disk First Aid again, which revealed no problem. The kernel panics occurred when booted in Safe Mode too. However, if I logged into a 'plain vanilla' user account the problems didn't occur. This would, I believe, indicate there isn't a problem with the hardware or RAM.


I suspected an rogue extension, and have been trying to uninstall apps that load code or extensions at startup, such as FullContact, Skitch, Yoink, CleanMyMac, and Things. To no avail.


I contacted Apple Support for advice on how to disable or remove other third party extensions but they said there was no method for doing this. They advised backing up, erasing the drive, reinstalling macOS, and restoring the backed up data but if the problem is extension-related it would likely recur.


The closest related post I have found is Kernel panic after latest osx Sierra update, but that only gets me so far. Any advice would be welcomed.

MacBook Pro (Retina, 13-inch, Late 2013), macOS High Sierra (10.13)

Hi BobHarris,


i have the same issue. Do you have any suggestions for me?


apfs error - Pastebin.com

Actually, I do NOT think you have the same original problem.


In your case, I think your anti-virus is messing with your system

  1. com.sophos.nke.swi 9.6.52
  2. com.sophos.kext.oas 9.6.53
  3. com.avatron.AVExFramebuffer 3.0.1
  4. com.avatron.AVExVideo 3.0.1

I do not know anything about avatron, but as it appears to be related to video, and your panic is in file system where anti-virus, such as Sophos like to insert kernel hooks, I strongly feel your problem is Sophos


I would the Sophos uninstall procedure (check their web site if you are not sure).


I would NOT install any 3rd party anti-virus. macOS does a good job all by itself

Please read "How does Mac OS X protect me?"

<http://www.thesafemac.com/mmg-builtin>

And Please read

<Effective defenses against malware and other threats>


If you want to run anything, then use MalwareBytes (written by a long time respected forum contributor)

<https://www.malwarebytes.org>

I am ONLY talking about the free option, where you manually run it if you suspect something, otherwise do not consume your Mac's memory and CPU resources having it continuously run for something that is unlikely to happen (again, because macOS does a good job).

Oct 5, 2017 3:51 PM in response to Nico Macdonald

Could you please post some of your panic reports?

Kernel Panic reports: Finder -> Go -> Go to Folder -> /Library/Logs/DiagnosticReports

<http://support.apple.com/kb/ht2546>

<http://support.apple.com/en-us/HT200553>

The panic report should have "panic" in the file name.


It might also be interesting if you post the EtreCheck output as a "Reply" to this thread

I'm running this on a Mac Pro 5.01 and have the same issues. Re-installed the system 4 times on a Kingston SSD, and it worked fine but after a while it panics after a reboot. What I've done so far:


- Reset PRAM

- Rebooted with -r (can't fix disk)

- Rebooted in s, en did a fsck. Disk appears to be fine


If I start from my other SSD on Sierra, the system boots fine. I am not able to repair the High Sierra disk though, when I try to repair the AppleAPFSMedia it always end up with:


"Storage system check exit code is 8"


Strange thing is, when I try to do a repair on the "Kingston" volume, disk utility crashes.

From my old Sun days I have some troubleshooting knowledge left, but I can't find the reason why this is happening.

For now I am back on my Sierra disk, which sometimes hangs, specially when I've been away for a while and try to log back in. Something I did not have in High Sierra.


Here's my pain log, seems to look a bit the same as from Nico.

I managed to get my high sierra disk to boot again.


I've move all my *.kext file from /Library/Extensions/ to an other directory.

My system started up just fine and everything seems to work as it should, Although I would believe that it would need the kext files I have removed.


The /Library/Extensions stays empty though, I am not sure if I can figure out which *.kext was causing the system to panic. As far as I know they should be in /System/Library/Extensions.


What I don't understand is that the timestamps have not changed, which I would expect if the system fails after a reboot on a (corrupt) kext driver.


Here's my list in case someone wants to know, only the GeForce and NVDA kext files are in my /System/Library/Extensions directory.

RJHMUSIC,


We need to see the panics you are getting to be helpful. As this is a user-to-user technical support fourm, we need information.


Please post the most recent kernel panic report(s). If you have more than one, it would be useful to see a few, as whether they are consistant or change will give us useful information.

<http://support.apple.com/kb/ht2546>

<http://support.apple.com/en-us/HT200553>

The panic report should have "panic" in the file name.


It would also be useful to see what, if any, 3rd party additions have been installed. This too can help diagnose your system.

Keep your virtual machine image, and just temporarily remove VirtualBox. If the system still failed, it is NOT VirtualBox and you can reinstall and continue to use your saved virtual image.


And if having NO 3rd party kernel extensions and it still panics, you should file a bug report with Apple

Have your previous repair receipt information, or case number when you next interact with Apple.


You can try the Genius Bar, as it cannot hurt. Since you have one failed repair, if the first level of Genius Bar does not want to replace, then ask to speak to a manager. If that is not satisfactory call Apple

<Contact - How to Contact Us - Apple>

Again, if no satisfaction, keep asking to speak to the next higher level of support.


But I suggest you always be polite, just insistent.

Mar 12, 2018 6:04 AM in response to rupertbarry

OK, lets start with the 3rd party RAM. This is just speculation, but 3rd party RAM has often been involved in kernel panics. HOWEVER, the kernel panic is not a traditional memory related kernel panic, but I do not see anything else obvious in your panic report.

Memory Module: BANK 0/DIMM0, 4 GB, DDR3, 1600 MHz, 0x859B, 0x435435313236344246313630422E43313646

Memory Module: BANK 1/DIMM0, 4 GB, DDR3, 1600 MHz, 0x80AD, 0x484D54333531533643465238432D50422020

I'm not sure if they are both 3rd party RAM, or if it is just one of them. But the very long hex number at the end of each line is not identical which indicates they are from different vendors.


You could try running Rember overnight to see if it finds anything

Rember

<http://www.kelleycomputing.net/rember/>

.

Quit as many apps and background tasks as you can (such as menu bar items) so more RAM is available for testing. Booting into Safe mode <http://support.apple.com/kb/ht1564> can also free up more RAM for testing, by not loading any 3rd party additions you may have installed.

.

Set Loops: [X] Maximum

and run overnight

Had the same problems. Turns out for me it where Chrome plugins (trusted ones) in combination with High Sierra!

Never ever had any problems with Sierra and never had any kernel panic in four years on my macbook.


Turns out it caused problems before:

It's been the case for literally decades that you cannot downgrade the OS of a machine past what originally shipped on it.


If you're still within your return period, you can simply return your new machine for a full refund:


Returns & Refunds - Shopping Help - Apple


If your issues are ones the Apple Store has helped you with before and has failed to solve, speaking to a manager may result in them allowing the return anyway.

The only 3rd party kernel extension you have is

com.malwarebytes.mbam.rtprotection 3.2.36

While the long time forum contributers often recommend MalwareBytes (as the Mac verison was written by a long time forum contributor), it is still a kernel extension, and as such can get into trouble when a new macOS version is released.


I would suggest uninstalling MalwareBytes for now, and see if the problems continue

Since the only current forms of malware affecting macOS are ones where the user is tricked into installing it, you can always re-install MalwareBytes after you have installed something to make sure whatever you installed in not carrying a malware side-package.


If removing MalwareBytes does not stop the system panics, you might consider whether your 3rd party RAM is causing problems.


You could run

Rember

.

Quit as many apps and background tasks as you can (such as menu bar items) so more RAM is available for testing. Booting into Safe mode <http://support.apple.com/kb/ht1564> can also free up more RAM for testing, by not loading any 3rd party additions you may have installed.

.

Set Loops: [X] Maximum

and run overnight


You could also move the 8GB DIMMs into the slots currently used by the 2GB DIMMs, and put the 2GB DIMMs in the previous 8GB DIMM slots.


You could also try removing the DIMMs one at a time to see if the problem goes away.
