The built-in speakers that come with most Macs are pretty darn good, especially (or so I’m told) on the iMac Pro. But if you want a high-end, expensive (about $700) set-up, you can pair two HomePods for some intense audio.
Apple says that setting up your stereo pair is easy and that “when you set-up a second HomePod in the same room, you’re prompted to form a stereo pair.” That’s true under ideal conditions.
Let’s assume that you are indeed working under ideal conditions and the set-up goes smoothly. Then your two HomePods communicate with each other so that only one responds to Siri requests. If both responded, you’d have a problem, of course.
Even though these two speakers act as one, each HomePod communicates with the other so that only one speaker responds to Siri requests. Unless this changes with the upcoming macOS Catalina, Apple says you can’t set up a HomePod with the Home app on Mac. Instead, you’ll need an iPhone, iPad, or iPod touch updated to iOS 11.4 or later, HomePod speakers with iOS 11.4 or later. And your Mac needs to be running macOS Mojave. Once all your software is up to date, make sure that your iPhone and Mac are on the same Wi-Fi network. Then, on your iPhone, iPad, or iPod touch:
- Make sure that both HomePods are in the same (virtual) room in the Home app.
- Open the Home app, press and hold HomePod, then tap Settings.
- Tap Create Stereo Pair.
- Choose a second HomePod to use as a stereo pair.
- Tap a HomePod on the right or left side to identify it. Tap the arrows button (see the icon above) to swap them to the correct left and right channel.
- To ungroup a HomePod stereo pair on your Mac:
- In the Home app, double-click the grouped HomePod speakers.
- Click Settings in the upper-right corner.
- Scroll to the bottom and click Ungroup Accessories.
I hope all this works for you. If you’re having problems, you may run into my situation, in which the Home app on my iPhone kindly told me: “HomePod features like airPlay and Personal Request may not work on ‘NETGEAR06’ because it does not support peer-to-peer connections.”
If this happens, you may have to disconnect and reconnect your router. This forces both HomePods to reattach to the network.
It’s also possible that the HomePods won’t sync properly. If this happens, you may hear different sounds from different speakers. Or you can experience a reverb/echo effect between the two HomePods.
If this is happening, make sure that both the speakers are using the latest iOS update that supports AirPlay 2. If that doesn’t work, reboot both the speakers.
If that doesn’t work, unpair and re-pair the HomePods. If that doesn’t work, you try resetting both. And if that doesn’t work, you’ll probably have to call Apple support.
