# MACaptionAppearanceDisplayType.alwaysOn

The most robust available captioning track should always be displayed, whether subtitles, CC, or SDH. This option is selected by a switch labeled “Closed Captions + SDH” (on the Subtitles & Captioning page of iOS) and “Prefer Closed Captions and SDH” checkbox (on the Captions pane of the Accessibility options in macOS).
