For many people, the default range of mouse scrolling speeds offered in the Mac OS System Preferences tab does not offer fast enough tracking speeds, especially on larger screens. In previous releases of Mac OS X, 3rd party preference tabs could be used to allow faster speeds and other formsof customisation (including mouse acceleration). Unfortunately, with the release of Mac Os Sierra, several of the internal calls used by these 3rd party utilities were removed, disabling their functionality.
There is still a way to enable faster mouse scroll speeds in Mac OS Sierra though, as detailed in this Apple Support article.
The new process is as follows:
- From the Apple menu, choose System Preferences.
- From the System Preferences window, select Accessibility.
- In the left sidebar, select Mouse & Trackpad.
- Click the Mouse Options button.
- In the sheet that appears, use the slider to adjust the mouse scrolling speed, including acceleration.
The “Mouse & Trackpad” accessability panel sheet gives quite a few good options, although still not as many as some of the 3rd party preference utilitities did.
