    I noticed that there are several kernel extensions in /Library/Extensions that are neither made by Apple nor were they installed by me. I happen to have access to a Snow Leopard partition and I can see that most of these extensions are present in /System/Library/Extensions (except the first two below), but not in El Capitan anymore. I presume that these extensions were moved to /Library/Extensions upon installing El Capitan, given that the System folder is now reserved.

    This begs the question: are they no longer needed? They are not actually active ("loaded") on my system. Can anyone verify whether they are there on a pristine El Capitan install?

    I have them on my 10.11 system, which was a fresh install.

    In that case I should probably just leave them where they are.

    Those have all gone into /Library/Extensions since at least 10.10. They are installed by the OS X installer.
