Apple today seeded the third beta of a new tvOS 12 operating system to developers for testing purposes, two weeks after releasing the second beta and a month after introducing the new software at the 2018 Worldwide Developers Conference keynote.
Designed for the fourth and fifth-generation Apple TV, the tvOS 12 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode. Subsequent betas can be downloaded via the software update mechanism on the Apple TV.

tvOS 12 brings support for Dolby Atmos sound, which was activated in beta 2. Apple says that iTunes will be home to the largest collection of Dolby Atmos-supported movies anywhere, with Apple upgrading titles customers have purchased for free.
Building on single sign-on, a new zero sign-on feature will further simplify the cable authentication process. With zero sign-on, the Apple TV can detect a user's broadband network and automatically sign them into supported apps they receive through their cable subscription.
Aerial screensavers include location information and there are new screensavers captured in collaboration with the International Space Station.
Other improvements to Apple TV in tvOS 12 include AutoFill passwords from iPhone, an Apple TV Remote automatically added to Control Center on the iPhone or iPad, and Apple TV support on Home control systems like Control4, Crestron, and Savant.
