Apple today seeded the fourth betas of watchOS 26, tvOS 26, and visionOS 26 to developers for testing purposes. The new betas come two weeks after the third betas were released.
The betas can be downloaded from the Settings app on each device. The betas are limited to developers right now, but watchOS 26 and tvOS 26 are expected to be made available to public beta testers this week or next. The updates will be released to all users in the fall.
All three new operating systems offer new features, with watchOS 26 and tvOS 26 adopt new Liquid Glass design changes inspired by visionOS, and watchOS bringing a new AI-powered Workout Buddy for motivation and the Smart Stack incorporates more personal context for better suggestions.
Meanwhile, tvOS 26 offers the ability to use an iPhone as a microphone for karaoke, new Aerial screensaver, and more.
visionOS 26 adds support for spatial widgets refinements to make personas more lifelike and support for shared spatial experiences between two Vision Pro users.
As usual, MacTrast and Apple both warn users to not install any betas on their daily driver Apple Watch, Apple TV, or Vision Pro. Instead, only install betas on a device set aside for testing purposes.
