The update can be downloaded from the Safari Technology Preview website, or if the browser is already installed, it can be updated via the “Update” tab in the Mac App Store. Full release notes for the update are available on the same website.

While the preview is intended for use by developers and advanced users, in order to provide Apple with feedback on the development of the Safari browser, it can be run side-by-side with the release version of Safari. The app doesn’t require a developer account to download and install.
