How can you securely destroy old versions of documents created by El Capitan-compatible apps such as Pages and Numbers? By "securely destroy," I mean erase them so that they are no longer recoverable on your hard drive? (For simplicity's sake, I am talking about an old-fashioned spinning-platter hard drive, not an SSD.)
And by "old versions," I mean the versions of documents that are accessible from the "Revert To (Browse All Versions)" function under the File tab.
(If this has already been covered well in another discussion, please point me in the right direction. Thanks.)
