tvOS 26 Limitations: Apple TV Hardware Requirements for New Features

Apple TV hardware requirements for tvOS 26's new features: Liquid Glass design available on Apple TV 4K (2nd gen and later), iPhone karaoke mode available on Apple TV 4K (3rd gen). Older models, such as Apple TV HD (2015) and first-gen Apple TV 4K (2017), will not support these features. Newer models, like the 2021 second-gen Apple TV 4K and later, will have access to these upgrades.

Apple TV users are eagerly anticipating the upcoming tvOS 26 update, set to debut this fall. However, the new software brings some hardware limitations that could impact the user experience. Key features such as the Liquid Glass design and iPhone karaoke support are only available on specific Apple TV models.

The Liquid Glass design, a visually appealing interface feature, will be available on Apple TV 4K (2nd generation and later). This means that older models, including the Apple TV HD from 2015 and the first-generation Apple TV 4K released in 2017, will not support this feature. Users with these older models will need to upgrade to the 2021 second-generation Apple TV 4K or later to enjoy the Liquid Glass design [1].

Similarly, the iPhone karaoke mode, which allows users to turn their iPhone into a microphone for Apple Music Sing, will only be available on Apple TV 4K (3rd generation). This feature is exclusive to the latest generation of Apple TV 4K, released in 2022. Users with older models will need to upgrade to access this functionality [1].

Apple has provided a detailed guide to help users determine their current Apple TV model. Given these hardware requirements, it may be beneficial for users to consider upgrading their Apple TVs if they wish to take advantage of these new features. A new Apple TV 4K model is expected to launch later this year, making it a good time to consider an upgrade [1].

In addition to these hardware-specific features, tvOS 26 will also bring other updates, including support for Thread 1.4. This protocol update addresses issues with competing Thread networks and provides direct internet access for smart home devices, enhancing the overall smart home experience [2]. The upcoming HomePod Software 26 is also expected to support Thread 1.4, further integrating Apple's smart home ecosystem.

For audio enthusiasts, tvOS 26 introduces a new passthrough audio option, which allows for better audio processing by external hardware. This feature is part of the AVFAudio framework and is expected to be implemented by developers in their apps or potentially made selectable in Apple TV settings. This could significantly improve the audio quality for users with high-end home theater systems [3].

In conclusion, while tvOS 26 brings exciting new features, users need to ensure their Apple TV hardware is compatible. Those with older models may need to consider an upgrade to fully experience the new updates. As always, Apple provides detailed guides and resources to help users navigate these changes.
