Safari technology preview 120hz update#
The update addresses a Safari issue where the current version of Safari appears to be limited to a 60Hz refresh rate despite the fact that the new machines support refresh rates up to 120Hz. Safari Technology Preview release 135 includes 120Hz Safari scrolling on displays that support 120Hz refresh rates. The preview version of Apple’s popular browser offers developers and other interested users the ability to try out features that may or may not, debut in future public release versions of Safari. Apple on Monday released Safari Technology Preview 135, the latest version of their developer preview web browser.
