On Monday, Apple released a new update to the Safari Technology Preview, which enables 120Hz scrolling on new MacBook Pro models.
Those with the 2021 MacBook Pros and enrolled in the Safari Technology Preview will be the first to try out the smoother scrolling experience while navigating the browser, as reported by 9to5Mac.
ProMotion was a leading feature Apple positioned when it came to the 2021 MacBook Pros. However, macOS Monterey does not currently support 120Hz for native Apple apps for one reason or another. The latest Safari Technology Preview will be the first step in rectifying that for users. That said, the Safari Technology Preview is a testing ground for new features. There’s no telling how long Apple will need to test 120Hz scrolling in Safari before they roll it out to all users with ProMotion support at their disposal.
On top of 120Hz scrolling, Version 135 also supports requestVideoFrameCallback API, lazy image loading, accent-colour, and new viewpoint units.
Version 135 of the Safari Technology Preview is available now. Safari Technology Preview Version 135 can be installed via the Software Update menu through System Preferences if you are already enrolled in the preview. If not, it can be installed on macOS Monterey and macOS Big Sur.
