Export Passwords & Bookmarks from Safari

Ensure Safari is open.
From Safari, select the File dropdown from the Menu Bar, then select Export, then select Passwords... or Bookmarks...

From the confirmation dialogue, select Export Passwords... or Export Bookmarks...

From the Export Passwords or Export Bookmarks window, in the Save As field enter Safari Passwords or Safari Bookmarks. In the Where field, select Documents.
Select Save when complete.

A dialogue window will open requesting your sign-on password.
Enter it, and select OK.

Safari will export all saved passwords.
To confirm successful export, open Finder, and select Documents from the left menu pane.
Safari Passwords.csv or Safari Bookmarks.html should be present in the list of files.

The Safari Password export is unprotected, and the passwords within are all in plaintext.
Once the passwords are re-imported, or referenced, the Safari Password file should be deleted, and the trash emptied.
