TvOS

tvOS (formerly Apple TV Software) is an operating system created and developed by Apple for the Apple TV, a digital media player. In the first-generation Apple TV, Apple TV Software is based on Mac OS X. The software for the second-generation and later Apple TVs is based on the iOS operating system and has many similar frameworks, technologies, and concepts. The second- and third-generation Apple TV have several built-in applications, but do not support third-party applications. On September 9, 2015, Apple announced the fourth-generation Apple TV, with support for third-party applications. Apple also changed the name of the Apple TV operating system to tvOS, adopting the camel case nomenclature that they were using for its other operating systems: iOS, watchOS, and (later, in 2016) macOS. The latest version, tvOS 27, was released on September 14, 2026.
