I wanted to check on the cookies stored when I visited a site using Safari 9.1.1 (10601.6.17) on a MacBook Pro laptop running OS X Yosemite (10.10.5). When I clicked on Safari on the Safari menu bar and then selected Preferences, then Privacy, I saw a "Cookies and website data" section, but no means to view the cookies, only a way to delete them by clicking on Remove All Website Data.
However, you can configure Safari to show details on cookies that are placed on the system when you visit a webpage by taking the following steps within the Safari browser.
