Apple today seeded the fourth beta of an upcoming tvOS 11 update designed for the fourth-generation TV, two weeks after seeding the third beta and more than a month after releasing the first beta during the 2017 Worldwide Developers Conference.
Registered developers can download tvOS 11 by connecting the Apple TV to a computer with a USB-C cable and installing the beta software using iTunes.
tvOS 11 didn't receive much attention at the Worldwide Developers Conference due to time constraints, but according to Apple's release notes, it introduces a few new features to the operating system.
tvOS 11 includes automatic switching between light/dark mode based on local time, Home screen syncing options that keep multiple Apple TVs in a household in sync, new background modes and notification support, Focus API improvements, custom sound support, network-based pairing and development support, improvements to Mobile Device Management, and more.
The fourth beta of tvOS 11 likely focuses primarily on bug fixes and other small refinements, as the first three betas did. Apple's new tvOS 11 update is available for both registered developers and public beta testers. It will see a public release later this year.
