I am using OS 10.10.1 on an older iMac. When I click on "bookmarks" in the menu bar my saved bookmarks show up in a left hand column. One of the bookmarks is "boat". Under "boat" there are a few sub bookmarks that want to delete. How do I do it?
Open Safari, click on "Bookmarks" on the top bar. A menu will drop, the second entry is Edit Bookmarks, click that. Now a new window opens up of the structure of your bookmarks. Find the one you want to delete, right click and click Delete. Done.
