Apple has released tvOS 27.2.1 for Apple TV 4K and HomePod 27.2.1 for HomePod models. The tvOS update is the latest version of the operating system for Apple TV 4K, arriving nearly three weeks after tvOS 27.2 and following the tvOS 27 operating system that launched in September. Although the version number suggests a minor change, tvOS 27.2.1 adds a significant feature: support for Siri AI on Apple TV 4K models.

Siri AI, the smarter and more capable version of Siri that Apple introduced earlier this year, arrived with the 4th-generation Apple TV 4K launch. A separate tvOS 27.2 build activates Siri AI on that newest set-top box, but the 2nd- and 3rd-generation Apple TV 4K models needed tvOS 27.2.1 to gain access. Siri AI can play content, draw on personal context to offer suggestions, answer world knowledge questions, and complete tasks. Using it on Apple TV requires a paired Apple Intelligence-compatible iOS device, which includes the iPhone 15 Pro and later. tvOS 27.2.1 also includes a variety of security fixes.S1S2

The HomePod 27.2.1 update, released alongside tvOS 27.2.1, applies to HomePod and HomePod mini models. Apple's release notes say only that it "provides bug fixes." When the HomePod mini 2 launched late last month, Apple said Siri AI would arrive through a future software update, but a leaker known as pdfu has confirmed that Siri AI is not included in HomePod 27.2.1. Users can get tvOS 27.2.1 by going to Settings > System > Software Update.S1S2
