1. In the Music app  on your Mac, do any of the following to play music:

* Stream songs from Apple Music

* Listen to an internet broadcast

* Play CDs

7. Click the AirPlay button  at the top of the Music window, then select the checkbox next to HomePod.

8. Whatever song you were playing in Music on your computer now plays on HomePod, too.

We hope this helps!
