Hi all, Parental Controls doesn't seem to work whatsoever for blocking websites. Also, I used to be able to delete system apps using terminal and now I don't have permission to do that, or to change permissions, or make them invisible. All new to 10.11. I'm trying to avoid the web on this machine and these safeguards help me focus. Aside from going back to Yosemite, any suggestions/workarounds for these problems are appreciated. Maybe some root user terminal access?
