Apple has just rolled out the first beta updates for macOS Tahoe 26, watchOS 26, tvOS 26, and visionOS 26, making them available to developers for initial testing. These updates come packed with new features and design changes that developers will want to dive into. If you’re a registered developer, you can easily download and install the latest beta versions through the Settings app on your compatible devices. 
Keep in mind that these updates are quite significant, bringing plenty of changes across the board.
Starting with macOS Tahoe 26, the update introduces a sleek new Liquid Glass design, which is consistent across all of Apple’s platforms. To download it, you’ll need to link your Apple ID to your Developer Account in the System Settings. If your account isn’t linked, the update won’t appear in the Settings, so make sure you’ve completed that step. Because this is a major update, developers are strongly encouraged to test it out to provide valuable feedback before its official release.
For watchOS 26, Apple has brought the same Liquid Glass design seen in macOS to the Apple Watch. Developers can install the beta by linking their Apple ID to the Developer Account, and then navigating to the Apple Watch app on an iPhone. From there, head to General > Software Update > Beta Updates to begin the installation process. This update brings a fresh look and feel to the WatchOS experience.
The tvOS 26 beta may not feature many headline-grabbing new additions, but the Liquid Glass design is enough to make this update worthwhile. In addition to the new look, tvOS 26 also introduces a handful of new utilities, including user profiles, which enhance the overall user experience. To install this update, head to the Settings app on your Apple TV and follow the prompts.
In addition to these updates, Apple has also released iOS 26 and iPadOS 26 for testing. You can install these updates on compatible iPhones and iPads to explore the new features and improvements. Keep an eye on our coverage as we dive into the details of these updates over the next few days.
