If you are using Safari, you’ll also need to use the print function.
Step 1: Start on the web page you want to save. Head up to File and choose Print, or press Command and P to open the printer window.
Step 2: Go to the lower left-hand corner of the window where it says PDF, and select this drop-down menu. Here you will see a number of options to save the PDF, save it into the cloud, save it as an instant message, open it in Preview before deciding to save, and so on. For a basic save, select Save as PDF… — otherwise, choose the option that best fits your needs.
