Hi Jon Corry,
If you'd like your Favorites in Safari to appear in a certain order, these steps might help.
While we understand why one might think that, "frequency of use" isn't currently a feature of Safari Favorites. You can rearrange them by dragging them as shown in Sort, alphabetize, or rearrange bookmarks in Safari on Mac.
Another option is to:
1. In the Safari app on your Mac, click the Sidebar button in the toolbar, then click Bookmarks.
2. Drag a bookmark or folder to a new location.
- To copy a bookmark, Option-drag it.
- To sort bookmarks in a bookmarks folder, Control-click the folder in the sidebar, then choose Sort By > Name or Sort By > Address. Address is the website URL.
If the issue remains after reordering your bookmarks, do you use iCloud Bookmarks or Reading List? We ask because we're wondering if that could be the cause of this issue. Check out If your iCloud or Safari bookmarks aren’t syncing for more information.
We hope that helps with your question and take care!
