How can I identify 3rd party kernel extensions in macOS?
You can identify 3rd party kernel extensions (Kexts) via Terminal.

More specifically:


Launch the Terminal app (found within your Applications > Utilites folder)
Type (or copy and paste) the following command:


kextstat | grep -v com.apple


Press Enter
Within moments Terminal will list all 3rd party kernel extensions (Note: you may need to stretch the Terminal window so it's easier to read). 


If you’re having issues with your Mac, you can use the above process to identify any 3rd party extensions you don't remember installing, or something that belongs to software you no longer use. 

Please note that this is a list of all 3rd party kernel extensions and any of them could be causing the problem.
