On your Mac, go to the Apple menu by clicking on the apple icon in the top-left of the screen and select ‘System Preferences’.
Click on ‘Keyboard’ and then ‘Input Sources’.
Click the add (+) button at the bottom of the window and then scroll down to find ‘Chinese, Simplified’ or ‘Chinese, Traditional’.
Simplified Chinese - If you would like to type in Simplified Chinese characters, used in mainland China, Singapore, and Malaysia, click on ‘Chinese, Simplified’. Next, select the type of Simplified Chinese keyboard you’d like to use from the list of options that appears. The keyboard you’ll probably find most useful is ‘Pinyin - Simplified’. If you would like to use trackpad handwriting to draw Chinese characters, select ‘Handwriting - Simplified’. Click Add.
Traditional Chinese - If you would like to type in Traditional Chinese characters, used in Taiwan, Hong Kong, Macau, and some overseas Chinese communities, click on ‘Chinese, Traditional’. Next, select the type of Traditional Chinese keyboard you’d like to use from the list of options that appears. The keyboard you’ll probably find most useful here is ‘Pinyin - Traditional’. If you’d like to use trackpad handwriting to draw Chinese characters, select ‘Handwriting - Traditional’. Click Add.
