Click the Safari app icon, which resembles a blue compass, in your Mac's Dock. It's a menu item in the top-left corner of the screen. A drop-down menu will appear. This option is near the top of the drop-down menu. Doing so opens the Safari Preferences window. It's at the top of the Preferences window. This option is below the "Cookies and website data" heading. Doing so will enable cookies in your Safari browser. You can also check a less liberal option, such as "Allow from websites I visit", to cut down on the number of third-party cookies on your computer.
