Apple on Monday released new 16.4 software for the HomePod, second-generation HomePod, and HomePod mini. According to Apple’s release notes, the update adds stability and performance improvements to the HomePod.
Your HomePod or HomePod mini should update automatically, but you can also manually update your device by doing the following:
Once you’ve tapped on “Software Update,” you’ll see the current version of the HomePod software that is installed on your HomePod or HomePod mini. You can also toggle off automatic updates if you want.
If there is an available update, tap the “Install” button to update your HomePod. If you have more than one HomePod or HomePod mini in your home, each one will be updated at the same time via this software update feature.
