Owners of fourth generation Apple TVs can beta test tvOS for the first time. Apple has expanded its Apple Beta Software Program to include the set-top box and tvOS 11.
Previously, the program has been limited to iOS and macOS while tvOS betas were only available to developers with paid accounts. The Apple Beta Software Program website says “iOS 11, macOS High Sierra, and tvOS 11 public betas are coming soon” and Apple promised public betas of iOS and macOS later this month.
If you're not already signed up for the public beta program, you can do so here. The program is free, but remember: beta software is unfinished software so use with care.
The first developer betas of iOS 11, High Sierra, watchOS 4, and tvOS 11 were issued on Monday.
