Apple has released Safari Technology Preview 241, continuing its regular cycle of updates to the experimental browser designed to test upcoming web technologies. First introduced in March 2016, Safari Technology Preview plays a key role in shaping future versions of Safari by giving developers and users early access to changes.
This latest update focuses heavily on stability and performance, with fixes spread across core web technologies. It reflects ongoing WebKit development and includes a wide range of refinements that improve how modern websites render, behave, and perform on macOS.
Safari Technology Preview 241 includes updates across Accessibility, Animations, CSS, Canvas, Forms, HTML, Images, JavaScript, MathML, Media, Networking, Printing, Rendering, SVG, Storage, Web API, Web Inspector, and WebRTC. Many of these changes resolve long standing issues, such as incorrect rendering behaviors, performance slowdowns in APIs like ResizeObserver and IntersectionObserver, and inconsistencies in CSS layout handling.
On the feature side, Apple has added support for the stretch keyword in box sizing properties, stable CSS scroll anchoring, and the auto keyword for responsive image sizing in HTML. There is also improved support for fractional coordinates in PointerEvent and TouchEvent APIs, which helps create more precise input handling in modern web apps.
Several fixes target real-world usability problems. These include improved media playback behavior, corrected handling of HDR video, better printing output for complex layouts, and fixes for flickering or rendering artifacts when scrolling. Developers will also notice improvements in Web Inspector stability and WebRTC enhancements for better real-time communication handling.
Safari Technology Preview 241 is compatible with macOS Sequoia and macOS Tahoe. Users who already have the browser installed can update it through System Settings under General > Software Update. The browser can also run alongside the standard Safari version, making it easy to test without affecting a primary browsing setup.
Apple continues to position Safari Technology Preview as a feedback-driven platform. It remains accessible without a developer account, allowing anyone interested in web development or browser behavior to test upcoming features and contribute insights.
