Apple Releases Safari Technology Preview 166 With Bug Fixes and Performance Improvements

Apple's 'Awe Dropping' iPhone 17 Event: Follow along with our live blog.

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 Feature
‌Safari Technology Preview‌ release 166 includes bug fixes and performance improvements for Web Inspector, CSS, JavaScript, Popover, Media, MSE, Web API, and Accessibility.

The current ‌Safari Technology Preview‌ release is version 16.4 and is compatible with machines running macOS Ventura and macOS Monterey.

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. 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.

Please Apple improves the Youtube experience on Safari on Intel Macs. Currently, it is an awful experience.

I heard it’s going to be snappier!! ?
Safari has been for awhile. There is little improvement now with faster AS Soc’s, and GHz ISP. So could say other browsers need to be as Snappy. :cool:

Even on an M1Pro the Youtube experience is like dog crap. Ok, maybe not sooooo bad, but sometimes extremely slow and hourly freezes that affect all tabs haunt me. - Chrome is so very much faster and quicker on loading web content. It just needs the second more on every request in safari, but because of the Passkey limitations, Chrome is just not a daily driver option for me. - add. many features in Safari are great and make it awesome to use, but the performance is just "slow" in real world usage.
