Turn off the Mac rootless feature.
Start and hold Command+R , enter recovery mode, open terminal , type:
csrutil disable
Enter and reboot. To re-restore, simply disable change to enable .
OSX 10.11 added the rootless function, as the name implies: to the root user lower permissions, the function is opened even if the root user or the sudo system is more important directory is not operational permissions.
