Every time I start my MacBook, everything works fine.

For around 3 minutes. Afterwards, it crashes with a kernel panic. I am forced to write this question in safe mode, as booting normally will make it crash again.

I know it's not Avast. The last loaded kext has nothing to do with this, I've disabled a few of the "last loaded kext"s and they didn't seem to do anything.

Can someone help me figure out what's wrong?

Sounds like you're on the right track with how you've started troubleshooting. Without knowing exactly what you've already tried, and for the benefit of others, I've outlined how I would normally proceed (keeping in mind that troubleshooting is a process of elimination and does require patience!).

Since you've already established the problem is not occurring when booted into Safe Mode then it's time to investigate login items, fonts, and kernel extensions.

Investigating login items, fonts, and kernel extensions

Let's start with Login Items:

  1. Startup normally
  2. Go to System Preferences > Users & Groups
  3. Select the Login Items tab
  4. Take a note of your Login Items
  5. Now remove all of them by highlighting them and clicking on the - button below
  6. Restart your computer

Now your Mac will boot up without those login items loading. Test to see if you can use your Mac without it crashing:

  • If you can, you know one (or more) of the Login items were causing the problem. You can then add them back in one by one until you've identified the culprit. Problem solved.
  • If the problem does persist, it's either a problem with fonts you've installed yourself or with a 3rd party kernel extension. A little more info below:

Fonts:- You can remove any of the fonts you've installed yourself to see if this makes a difference.

Kernel Extensions:- You can open Terminal (found within your Utilites folder) and enter the following command:

kextstat | grep -v com.apple

The above command will list 3rd party kernel extensions (you may need to stretch the Terminal window so it's easier to read). Look for anything you don't remember installing, or something that belongs to software you've removed, or just anything that looks out of place. Remember though, this is a list of 3rd party kernel extensions and therefore any of them could be causing the problem.

If your Mac continues to crash once you've gone through the above process, I would suggest that continuing to troubleshoot this will cause more frustration and take more time than just cutting your losses and doing a fresh installation of macOS.

  • My guess is the cause has been there in the crash report the whole time. IOVideoPocketCamDevice[0x100000498]::terminate(kIOServiceSynchronous). IOVideoPocketCamDevice was a .kext in my /Library/Extensions folder. I disabled that and /System/Library/Extensions/PocketAudioDevice.kext (both Senstic drivers). Doesn't seem like macOS has crashed yet. – Dev Dec 13 '17 at 4:11

    @MelvinJefferson Sometimes that is the easier way to go, assuming the user has a current reliable backup. It'd almost certainly resolve the problem, so long as it's not reintroduced because of some buggy 3rd party software. But first spending a couple of hours to do some basic troubleshooting is worth it in most cases. :) – Monomeeth Dec 13 '17 at 4:16

    @Dev That wouldn't surprise me. The Senstic and Techsmith ones stood out a little in that list of 3rd party kexts. I did try to load the Senstic forums earlier to see if anyone else had reported issues with macOS High Sierra, but I couldn't get their forums page to load. Hopefully that will have sorted the problem for you, though. – Monomeeth Dec 13 '17 at 4:26
