I never touched a thing and (on 10.13 ß): $ sudo su -l password: Galileo:~ root# ps -u root | wc -l 115 - You can't log into the UI as root (by default), and that is a good thing. - SEP prevents you (or any random script/software/installer you run) from meddling with system files and that is a good thing too, no different from sensible SELinux or AppArmor policies.
