If you ever wanted to have a link to a website without bookmarking it in Safari, here’s a way to add it to your Dock. From the desired webpage go to the website field at the top of Safari. A “+” will appear to the left of the website. Click and drag that “+” to your Dock.
Make sure you are on the far left side of the Dock.
Drop it onto your Dock and a globe icon will appear. Now whenever you click that icon Safari will open and go to that page.
