I just want to verify the following holds true for installing kexts in 10.11 via the shell and that there are no other steps missing:

sudo cp -R some.kext (/System)/Library/Extensions/ # Add or remove /System based on location of kext on this and next ones sudo chown -R root:wheel (/System)/Library/Extensions # maybe add: `sudo chmod -R 755 (/System)/Library/Extensions/` sudo touch (/System)/Library/Extensions

As I understand it, it may be useful to also do the following as far as the kext caches go in current OS releases:

# For /System; not sure of location for /Library centric kexts: sudo rm -R /System/Library/Caches/com.apple.kext.caches sudo kextcache -u / # or /Volumes/"Whatever volume name"

Fix disk permissions

sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume / # Fix Homebrew folder if you use it: sudo chown -R "$USER":admin /usr/local

Reboot:

sudo reboot

*NOTE: the process seems to have changed over the last couple years from this (especially with regards to the kext caches) and I would like to receive verification.
