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.

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.

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

Please post the EtreCheck output as a "Reply" to this thread

<https://discussions.apple.com/docs/DOC-6174> or <https://etrecheck.com>

Use the EtreCheck -> Edit -> Copy Report (See the image below)

And then Paste the report as a "Reply" to this thread.

If, AND ONLY IF, you get the error:

"The message contains invalid characters"

then try posting to PasteBin.com, and give us a PasteBin URL link.

EtreCheck is a tool that helps Apple Support Community volunteers debug problems without any access to the troubled computers. Debugging problems can be a difficult task even when the machine is in front of you. Attempting it via a discussion forum is extremely difficult. EtreCheck is a great help that regards.

It is possible you have a hardware issue, but we can only look at the information you give us, and then may recommendataions.

Hello and thanks for your reply Luis!

Although I did do a clean format and then install (I always do it with a new OS) and I'm getting kernel panics after 20 minutes or so...

Did you migrate everything after that clean install?

You may want to run the diagnostic tool Etrecheck and post its report here.
