It’s something that may not be of particular interest to the average web browsing-user, but will cause great excitement amongst the development community who not only create web experiences and software for Safari on a regular basis, but also troubleshoot issues regularly. Those installing the latest Safari Technology Preview will be able to get an instant preview of the latest advances that have been made in Safari web technologies, which includes HTML, JavaScript, and layout tech like CSS. Safari Technology Preview also includes the most recent update of WebKit, which is the underlying rendering engine that gives the Safari web browser its power. Also thrown in is the ECMAScript 6, which is the latest version of JavaScript, and speaking of JavaScript, it has now got its own dedicated compiler called B3.

To make the whole experience a lot easier and more manageable, Apple will be delivering regular updates of the Preview via the Mac App Store software update mechanism. This version of Safari can exist separate to the regular Safari browser on the same machine, and also comes with iCloud Sync support, allowing users to import settings and bookmarks from their regular Safari browser.


The Technology Preview ships with the latest powerful developer tools, including Web Inspector and Responsive Design Mode to test layouts and experiences across a wide-range of simulated device types.
