Alphabetically Sorting Safari Bookmarks How can I get my Safari bookmarks automatically sorted alphanumerically within Bookmarks manager?

I want to accomplish this without installing a bookmark management tool, nor by going through the process described at this link 1.
You cannot. Safari does not include that functionality.

You can easily achieve sorting using plugins such as SafariSort, but as you write that you do not in want to use any third party tools - you're out of luck.

You should consider using another browser if this functionality is important to you.
