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

Safari Technology Preview release 52 includes bug fixes and feature improvements for Service Workers, Loading, JavaScript, CSS, Web API, Accessibility, Web Driver, Web Inspector, WebAssembly, and Media. Today's update also removes support for running legacy NPAPI plug-ins other than Adobe Flash.

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.

YouTube still doesn’t support the standard codec, so no.
It's much worse than that.

If you submit a 4K file to YouTube that's already H.26x, they transcode it to their format and delete the original.

It's a dick move.

I didn’t know that anyone actually used Safari, other than on iOS where we’re forced to against our will.
I use Safari. Chrome is ugly and uses more battery.

Horizontal tab management in Safari 2018 (reported since STP v1!! - not even 20 tabs - happens both left and right side with more open). Imagine using this "professionally", it saves battery though! :rolleyes:

You can use scrolling of the tabs or Tab View function.

I will answer everyone's question, does it play 4K Youtube? No.
And it never will until YouTube supports it (which they won’t).

We use it daily intensively, a lot of feedback they just don't care to fix, we always have to end up on Chrome for professional dev use, pretty sad.

EDIT: if you are a casual user it may be ok.
