Introducing macOS Tahoe Beta Testing

We're excited to announce that TestingBot now offers early access to Apple's upcoming macOS release: macOS 26, also known as macOS Tahoe. This is Apple's first beta build of the new version, and you can start testing today on real macOS machines through TestingBot.

Whether you're a developer, designer, or QA engineer, this is your opportunity to prepare your app, site, or experience for the brand-new Liquid Glass design—Apple's most refined macOS interface yet.

What's New in macOS Tahoe (macOS 26)?

• Liquid Glass UI: A translucent, layered design with depth-aware components.
• Smoother animations: Enhanced visual performance and transitions.
• Safari 19: A new tab experience with rounded tabs that float in the toolbar, plus a streamlined sidebar.

With these changes, both native apps and websites appear lighter and more modern. Now is the perfect time to test how your interface adapts.

Why Test Now?

macOS 26 is expected to release publicly in Fall 2025. But TestingBot users can already:

• Test their website on Safari 19 before it hits general release.
• Ensure compatibility with Apple's newest design system.
• Preview how native apps look with the Liquid Glass aesthetic.

How to Start Testing

To start, log in to your TestingBot dashboard and select:

• Operating System: macOS 26 (Beta) – Tahoe
• Browser: Safari 19 (Beta)

You'll instantly launch a real, single-use, macOS 26 machine on TestingBot, no configuration or installation required.

Stay Ahead with TestingBot

With millions of Apple users preparing to upgrade to macOS Tahoe this fall, now is the time to ensure your experience shines in the new environment. From browser compatibility to visual fidelity in Liquid Glass, TestingBot has you covered.
