Me no understand. I have the latest version of Sierra installed. On Dec 17, this article was published: http://www.digitaltrends.com/computing/how-to-password-protect-folder-windows-mac-os-x-apple-microsoft/2/
Why, then, do the instructions & windows shown in the article differ from my experience of the macOS folder encryption process?
The differences are slight but enough to mislead/confuse a less-astute user than myself.
