    Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced in March 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

    Safari Technology Preview release 73 includes bug fixes and performance improvements for Web API, JavaScript, CSS, Media, WebRTC, Web Animations, Web Authentication, WebGPU, and Web Inspector.

    The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that was released to the public in September 2018.

    The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store to anyone who has downloaded the browser. Full 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 designed for developers, it does not require a developer account to download.

    Does Apple still work on Safari? I thought they gave it up.

    Yeah, finally, I can't believe Apple allowed this function to be so screwed on Safari. I mean, scrolling through a video on YouTube is one of the first things a customer is going to try on its new device. I tried several times to scroll through a YouTube video with the TouchBar and it was impossible. I can't believe this took them two years to be fixed.

    I’ve been using the Preview as my default browser for some time now. Always stable.

    The inventors and 90% contributors aren't giving up on WebKit 2 that is integral to iOS, tvOS, macOS and watchOS.

    WebGPU getting Metal shading sure is going to be nice once it's fully implemented. WebRTC updates are welcome as well

    They update it with every major macOS (and iOS) version.

    Blame Google for that not working on YouTube. It works in Chrome, because it supports the codec Google decided to use (VP9 I think but I could be wrong).

    The unfortunate state of affairs now is that the only two significant web rendering engines being developed are WebKit and Blink, which is a fork of WebKit. Both Edge and Firefox will soon be relying on Chrome's Blink renderer.

    Monocultures are bad. It's not hard to imagine a scenario where a major security bug is found which could affect basically 100% of web browsers.

    While Edge (Microsoft) is bailing and going Blink, I haven't heard anything about Mozilla, so while a prediction for Firefox at some (which I'd count possibly likely given their market share trends) I wouldn't toss them in there quite yet.

    I agree with you on monocultures for the window people view the internet through and the power it hands the owner (Google for the most part now) - am using Firefox everywhere I can just to add another number to it.

    Is there a functional dark mode on Safari yet or am I just a dreamer? Currently I am using the Dark Mode extension but it isn't very good. Need a proper natively supported dark mode. Also, any ideas on which experiemental features are least stable so I can disable them? I know sometimes dev preview doesn't render right and normal safari does and it is usually an experimental feature causing the issue but it's too hard figuring out which one. I'd rather just leave disabled the ones everyone already knows aren't very good.

    update - just installed Dark Reader for Safari and wow, it blows away Dark Mode for those who are also looking for a good upgrade extension until the world embraces native dark mode.

    Firefox's performance wipes off Safari without breaking a sweat. IMO is the most performant browser far, they truly took it to the next level with Quantum.

    Firefox rolled out Quantum, a major update to their renderer, a little over a year ago and keep improving it. Firefox is fast for the first time in years. Why do you think they are pulling a Microsoft and killing it off in favor of Blink (and can I just take this opportunity to mention that Chrome/Blink are turds on MacOS)?

    We already do. HEVC (or H.265) is a new industry standard codec.

    I thought I’d read Firefox intended a switch to Chrome’s renderer, but now I can’t find the reference. Hopefully I was mistaken - we really need an independent rendering engine.

    I wish Safari didn’t freeze for a second or two everytime I swiped back, would make it much more tolerable to use.

    Ugh I hate that. You’d think they’d figure that out by now.

    Seems very hit or miss, almost dependent on the website and what all scripts and crap have to load in the background. Lightweight websites load instantly and are instantly meanuverable when I swipe back, but heavy ones seem to want to reload the entire site again which causes a white screen for a second or two.
