Apple today released a new update for Safari Technology Preview, the experimental browser that was first introduced in March 2016. Apple designed Safari Technology Preview to allow users to test features that are planned for future release versions of the Safari browser.

Safari Technology Preview 234 includes fixes and updates for Animations, CSS, HTML, JavaScript, MathML, Media, SVG, Web API, Web Authentication, Web Inspector, and WebRTC.

The current Safari Technology Preview release is compatible with machines running macOS Sequoia and macOS Tahoe, the newest version of macOS.

The Safari Technology Preview update is available through the Software Update mechanism in System Preferences or System Settings to anyone who has downloaded the browser from Apple's website. Complete release notes for the update are available on the Safari Technology Preview website.

Apple's aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while it is designed for developers, it does not require a developer account to download and use.

The good news is that it finally stopped crashing 2 to 10 times per day. Maybe there is hope? Nope, this is probably just a random code change that fixed the problem.

I really don’t like the way Safari 26 handles the bookmarks sidebar now. Before this update, when you opened the sidebar, all your bookmark folders were shown in a clear hierarchy, and you could just click a folder to reveal its contents underneath. But with Safari 26, it slides out to the right, opening a new screen with your bookmarks (and some preview icon), which feels really awkward. If you have a lot of folders within folders, organized during years of use, this new system makes it easy to lose track of where you are in the hierarchy. Plus, now I always have to go back every time I finish browsing a folder, which is super annoying. Navigating my bookmarks on Safari 26 has become a chore, and since this is the way I mostly browse the web, I had to go back to Safari 18 for the time being.
 
I use safari for online shopping and Chrome for everything else. It would be nice if Apple would put a bit more effort into Safari... but hey.... then where would Siri be? 😂 oh wait.. nm.
