OS X shares my volumes/drives and home folders by default and I can not limit or remove access to them.
It doesn't matter if I have shared folders or not, if I turn on this sharing feature all my drives are accessible from another computer after I log in. I don't want to share any drive, I just want to share one or two folders.
What can I do about it? It's a serious security issue.
iMac, OS X El Capitan (10.11.5)
