Third beta of tvOS 12 goes public

Apple seeded the third tvOS 12 public beta update to public beta testers Wednesday, less than two weeks since the release of the second version.

tvOS 12 adds Dolby Atmos cinematic audio support, which was activated in the second beta version. Apple says iTunes will add Dolby Atmos content as well, and iTunes libraries will be upgraded for free on all 4K-supported titles. 

tvOS 12 will also add ‘zero sign-on,’ the new technology through Apple TV that will detect the user’s Wi-Fi network and automatically sign them into all the supported apps they receive through their subscription. Zero sign-on will begin with the cable company Charter Communications later this year and will expand to other providers over time, the company said.

Other improvements to Apple TV in tvOS 12 include ‘Ariels’ screensavers with the addition of videos taken on board the International Space Station in 4K, high-definition, AutoFill passwords from the iPhone to sign into Apple TV apps, an Apple TV Remote automatically added to Control Center on the iPhone or iPad, and support on Home control systems like Control4, Crestron, and Savant.

tvOS 12 is scheduled for final release this fall.

The tvOS 12 public beta can be found by going to the Settings app on Apple TV, navigating to ‘System’, then to ’Software Updates’, followed by toggling on ‘Get Public Beta Updates’. The Apple TV can also be set up to receive updates automatically by turning on the ‘Automatically Update’ selection on the same screen.
