Every time I start my MacBook, everything works fine.

  1. Avira Antivirus Pro was one point behind with 16.5 points, while Avast Security and F-Secure Safe were the last products in the charts with 16 and 15.5 points, respectively.
  2. Avast on macOS High Sierra claims it has caught the Windows-Only “Cryptonight” virus. Besides the new Mac operating system (macOS High Sierra 10.13.1). But I am unsure since I only have one MacBook and no one else that I know that has a mac has updated the OS to High Sierra. But Avast keeps labeling this as a potential “Cryptonight.

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.

Non-Apple kexts that are loaded:

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

Avast mac download

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:-Avast for mac vs total av for mac. 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.
