Apple unveils latest safari technology preview update: New features and enhancements


Apple has introduced a fresh update for Safari Technology Preview, the innovative browser initially launched in March 2016. This experimental browser serves as a platform for testing potential features that might find their way into upcoming iterations of Safari. The newly released ‌Safari Technology Preview‌ 177 focuses on enhancing several aspects, including Web Inspector, CSS, Rendering, Popover, Media, JavaScript, Web API, Accessibility, and Apple Pay.

A notable inclusion in this update is the integration of content that aligns with Safari 17, working in conjunction with macOS Sonoma. On Sonoma, users can explore Profiles, a feature designed to segregate browsing data such as History and Favorites, alongside improved private browsing capabilities. Features benefiting all operating systems include Feature Flags, a replacement for Experimental Features, an overhauled Develop menu, and Live Text support for recognizing vertical text within images and videos. Additionally, the update introduces support for HEIC and JPEG XL, an advanced image format boasting enhanced compression algorithms for superior image quality at reduced file sizes compared to traditional JPEG.

The current iteration of ‌Safari Technology Preview‌ is fully compatible with machines running macOS Ventura and the beta-tested macOS Sonoma. To obtain the update, users can utilize the Software Update mechanism available within System Preferences or System Settings.


Apple’s primary goal with ‌Safari Technology Preview‌ is to foster collaboration with developers and users, inviting them to participate in the browser’s development process. Designed to coexist alongside the standard Safari browser, ‌Safari Technology Preview‌ is a versatile tool targeted at developers. Notably, it doesn’t require a developer account for downloading, making it accessible to a wider audience.

Through its consistent evolution, Safari Technology Preview continues to be a conduit for Apple to gather invaluable feedback on browser advancements. The platform facilitates seamless side-by-side usage with the standard Safari browser, underscoring Apple’s commitment to an inclusive and collaborative approach in refining its browser offerings. Complete release notes for the update can be accessed via the Safari Technology Preview website, encouraging users and developers to explore the details and contribute to the browser’s ongoing refinement.
