Enabling JavaScript on Safari for macOS

To enable JavaScript in Safari on a macOS device, you need to access the browser’s Preferences menu. Begin by launching Safari and then follow these steps carefully to ensure JavaScript is activated:

Open Safari and click on the Safari menu located in the upper-left corner of the screen.
Select Preferences from the dropdown menu.
In the Preferences window, click the Security tab.
