The new 14/16-inch MacBook Pro in 2021 has received wide acclaim after its launch. One of the popular improvements is the introduction of 120Hz ProMotion. Just like the smooth scrolling experience of the iPad Pro and the new iPhone 13 Pro series, Apple promises that the high refresh rate of the new display will make “tasks such as scrolling web pages super smooth.”
Unfortunately, the current macOS applications that support ProMotion’s availability are sporadic and incomplete, and there are many areas that need follow-up improvements. Just likeiPhoneIn the early days of the 13 series, there was some confusion in ProMotion. under these circumstances,AppleFinally, additional documents are provided, explaining what developers need to do to fully adopt the feature, and promised to provide software updates to fix some related errors.
According to netizens in the newMacBookIn the actual test on Pro, Catalyst apps can work normally at 120Hz refresh rate, because they seem to directly inherit the behavior of iOS. Full-screen games and Metal applications can also be rendered at 120Hz.
The problem is that most everyday standard Mac applications are not like this. In particular, the smooth scrolling provided by ProMotion is not utilized in many applications. The most obvious is Safari. Apple specifically mentioned the use of the high refresh rate of the new display in the ProMotion section of the press conference.
For third-party applications, Apple has not released any supporting documents to guide developers on how to do it. For example, you can see this topic on the GoogleChrome forum. Chromium developers want to use the ProMotion display, but in actual operation they have reached a dead end and don’t know where/how to start.
