Safari is a beast, just like Chrome.
Now, I want to caution you-- there
are many things that are listed here that are not supported
by the commercial tools.
Different databases of interest.
CloudTabls.db.
Bookmarks.db.
SafariTabs.db.
History.db is heavily supported.
But then we have all of these additional things--
Safari thumbnails, favorite icons, Cache.db,
and com.apple.mobilesafari.plist.
You should examine every single one of these files.
I can tell you, the vendors are chasing
to try to catch up with Safari.
You need to make sure you're examining
these files of interest.
