Use the Candidate window to type Chinese or Cantonese on Mac
When you type an input code, the Candidate Window shows all possible characters for the code (including emoji for Pinyin and Zhuyin). If you set the predictive completion preference for an input source, the Candidate window also shows the most relevant predictions as you type. In the Candidate window, choose the characters you want to use in your document.
Trending Chinese or Cantonese words and phrases, which appear as typing suggestions in the Candidate window (and the Touch Bar, if you have one) as you type, are regularly updated automatically in the background.
