How to merge two or more Safari Bookmarks.plist files together? I do not use iCloud to sync my Mac and I have several Safari Bookmarks.plist files that were manually backed up at different times. Thus each contain some of the same items while some contain items the others do not.

How can the contents of these Bookmarks.plist files be merged together?
Neither macOS or Safari provide a direct way to merge multiple Bookmarks.plist files so as not to contain duplicate items.

Some choices are:


Manually import each Bookmarks.plist file (Safari > File > Import Bookmarks...) and then manually arrange and reorganize while manually deleting duplicates. 
Use a third-party utility to manage the Bookmarks.plist files so as to utilize any tools the third-party utility provides to remove duplicate items.


BookmarkApp: sort &amp; delete duplicate bookmarks


Developer Website
Mac App Store Preview

URL Manager Pro : the bookmark manager

Safari Extensions - Search for: bookmarks - At the time of this search it contained "69 results found for 'bookmark'", and some may have the capacity to remove duplicates.
Google, or other Search Engine, for other third-party utilities to manage Bookmarks.

Write your own utility to manage Safari Bookmarks to remove all duplicates from a set of combined Bookmarks.plist files.
