kextfind – show kernel extension files
kextfind is a cool utility from the kext* toolkit of standard macOS commands. Run without any parameters, it will show full path to every kernel extension on your system.
IMPORTANT: by default kextfind shows you all of the kernel extensions, not just the active ones.
If you just want to see active (loaded) kernel extensions, use the kextfind -loaded variant of the command.
