Setting up the HomePod is pretty easy, and only takes a couple of minutes. However, if you're coming across a mysterious blank white window during the setup process, here's how to fix it.

The HomePod relies on Apple Music as its streaming service whenever you want to tell Siri on the HomePod to play a specific song, artist, or album. You can use your HomePod even if you don't subscribe to Apple Music, but you'll run into an error during setup after you pick its room:

This happens when the Apple Music app is not installed on your iPhone or iPad, usually because you deleted the app at some point in the past. Normally, that blank screen would show this:

But since the Apple Music app isn't installed on your iPhone or iPad, it doesn't know what to do and just freezes there. A similar thing might be happening if you don't have the Home app installed as well.

So how do you fix it? Start by opening up the App Store and tapping on the Search tab down in the bottom-right corner of the screen.

Tap on the search bar at the top.

Type in "Apple Music" and hit "Search".

You might have to scroll down a bit, but once you find the Apple Music app, tap on the download button to the right.

Wait for it to download and once that's done you'll be ready to go---the setup process should proceed without hiccup! Again, you'll want to do this with the Home app as well (if you deleted it in the past), since that's where all of the settings are to customize your HomePod.
