Closed Captions are available for live and on-demand courses within specific browsers. Below will show you how to access and turn on the browser setting.
On your Mac, choose Apple menu > System Settings, click Accessibility in the sidebar, then click Live Captions (Beta) on the right. (You may need to scroll down.)
Turn Live Captions on or off.
The Live Captions window appears and stays on screen. If you want to hide the window when no audio is detected, click the Live Captions icon in the menu bar , then make sure Keep Onscreen isn’t chosen.
Note: The first time you turn on Live Captions, language data is downloaded to your Mac. You must be connected to the internet.
