In Windows, it's common to write shared data to %ProgramData%\path\to\stuff. From there, programs installed for any user can access it as a sort of "source of truth" or common repository. Usually writing to this directory is a low-privilege operation, unlike writing to %ProgramFiles%.
What's the right thing to do for data meant to be used for one or more users in OS X/Sierra? Preferably without privilege escalation?
Context is third-party pkg installer, not a sandboxed app.
