Apple Releases Safari Technology Preview 157, With Performance Enhancements and Bug Fixes

The experimental browser Safari Technology Preview, which Apple first revealed in March 2016, received a new update from Apple today. Apple created the Safari Technology Preview to test out features that could be added to later versions of the browser.


Bug fixes and performance enhancements for Web Inspector, CSS, Rendering, JavaScript, Web API, WebCodecs, Media, Web Animations, HTML, Privacy, Accessibility, Security, and Safari Web Extensions are included in Safari Technology Preview release 157.

The Safari 16 update is the foundation of the latest Safari Technology Preview release. It supports features from macOS Ventura like Live Text, Passkeys, enhanced Web Extensions, and more.

Unlike early versions of Safari Technology Preview, the most recent build is compatible with devices running macOS 13 Ventura. However, macOS Big Sur is no longer compatible with it.


Anyone who has downloaded the browser can access the Safari Technology Preview update using the System Preferences Software Update feature. On the website for Safari Technology Preview, you can read the update’s complete release notes.

With Safari Technology Preview, Apple hopes to get user and developer feedback on its browser development process. The Safari Technology Preview browser can coexist with the default Safari browser. Despite being intended for developers, downloading does not need a developer account.
