Since OS 10.11, the Root is sandboxed. You cannot save to it.

In fact, without running certain Terminal commands, you cannot access the Root. Definitely not recommend unless you really know what you’re doing—and then only to remove old code that is causing modern problems (older installs of Soundflower come to mind).
