iOS 27.2 brings several key new features to Apple's HomePod lineup, including the ability to use HomePod speakers as the default sound output for Mac. Both the 2nd-generation HomePod and HomePod mini 2 can now function as low-latency wireless speakers for Mac desktops and laptops that support Wi-Fi 6E.
Apple has significantly reduced latency when using a HomePod as a wireless speaker for Mac, making it viable for real-time audio applications like Logic Pro and FaceTime calls. The update creates an ad hoc point-to-point connection between the Mac and HomePod, similar to how it works with Apple TV, rather than relying on traditional AirPlay.
For the HomePod mini 2, Apple included a different Wi-Fi/Bluetooth architecture based on PCIe and revised audio routing to prioritize low-latency applications. The Wi-Fi 6E requirement applies to the Mac hardware itself and doesn't require a 6E-enabled router. Apple is so confident in the low-latency connection that it defaults to playing sound effects via AirPlay when a compatible HomePod is selected as the output destination.
The update also introduces new features like Sound Glow, Lock Controls, and home theater surround sound support.
