Apple has released the first developer betas for watchOS 26.6, tvOS 26.6, visionOS 26.6, and HomePod Software 26.6, marked by build numbers 23U5025e, 23L5729e, and 23O5728e, respectively. These updates are part of a testing cycle that follows the recent public release of version 26.5, which brought enhancements such as a new Pride Luminance watch face for the Apple Watch and general stability improvements for Apple TV and Vision Pro. Although Apple has not disclosed specific changes in these new builds, it is anticipated that the updates will primarily consist of under-the-hood performance enhancements and bug fixes as the company gears up for the upcoming WWDC26. Developers registered with Apple can download the new software through the Software Update menu in the Settings app on their devices. For watchOS, the update must be initiated via the Watch app on a paired iPhone.
