Apple today began seeding developers with the fourth build of tvOS 10.2 for testing on the Apple TV. This comes a day after the fourth betas of iOS 10.3, macOS 10.12.4, and watchOS 3.2 surfaced and two weeks after the third build became available.
So far, nothing new has been spotted in this beta of tvOS 10.2. Features already discovered include accelerated scrolling support for UIKit and TVMLKit apps, Device Enrollment Program support, Expanded Mobile Device Management support, and support for the VideoToolbox framework. Of course, if you spot something worth mentioning, you can tip us at firstname.lastname@example.org and @MBEDDEDMaximum on Twitter.
To install the latest tvOS 10.2 beta, head over to Settings > System > Software Updates > Update Software on your registered fourth-generation Apple TV and hit the download button.
