In addition to bold, italics, underline, and strikethrough, you can instantly add playful, animated effects to any letter, word, or phrase in iMessage. Or let macOS suggest effects to apply as you type. Whether you want to emphasize some major news, bring your emoji to life, or you’re just blown away, text effects give you new ways to visually amplify your texts. Some words and phrases automatically display a suggestion, and you can also add one of the many new effects to any text.
