The new 14 and 16-inch MacBook Pro models have received good reviews for their high performance, excellent battery life, increased physical connectivity and 120Hz Mini LED displays (ProMotion). Apple has given special attention to the latter; saying that everyday tasks such as scrolling the web pages will become very smooth. Unfortunately, high refresh rate support in macOS applications is still poor.
As it became known, Catalyst test programs, full-screen games and Metal applications work on the new MacBook Pro with a refresh rate of 120 Hz, but ordinary applications with which users work most of the time are deprived of this opportunity. In particular, the smooth scrolling that ProMotion can provide is not used in most applications. Most noticeable is the lack of 120Hz support in the Safari browser; which Apple demonstrated smooth scrolling during the presentation of new laptops.
Curiously, Apple hasn’t released any accompanying documentation for third-party developers explaining how to adapt apps to the new high refresh rate screens. For example, there is a thread on the Google Chrome forum where the Chromium developers have been looking for ways to take advantage of ProMotion displays on their own, but so far they are stumped.
Especially funny is the situation with the support of 120 Hz refresh rate in native applications for macOS, beaten by Twitter user Moshen Chan. He demonstrated smooth scrolling on a Mac in a Chrome browser running in a virtual Windows machine on the new MacBook Pro. At the same time, Safari showed a stable 60 fps and no more frames.
We do not know when Apple will provide tools to allow developers to adapt macOS apps to high refresh rates. This is likely to happen with the release of the next macOS Monterey updates.
