By default, HomePod and HomePod mini automatically install new software updates, but you can manually check for updates in the Home app on your iPhone, iPad, iPod touch, or Mac.
- Make sure that your device is updated to the latest version of iOS, iPadOS, or macOS.
- Open the Home app. Select Home , then Home Settings > Software Update.
- Select HomePod to turn automatic updates on or off. If there's a new update, select Update. Software Update will also tell you if your HomePod is already up to date, and show you the installed HomePod software.
A white spinning light appears on the top of HomePod while it's updating. The update might take some time. Make sure that your HomePod stays plugged in while it's updating.
