Currently using a Razer DeathAdder gaming mouse with the driver software installed, and I have tried adjusting the scrolling speed in the system preferences in both Mouse Settings and in Accessibility (not sure why there is 2 different settings).

If anyone has any suggestions, I would greatly appreciate it. I have to scroll through a lot of code when I work and my pointer finger is getting disproportionally muscular.

Using macOS Sierra on a 27 inch Late 2013 iMac.

Figured out the problem. The Razer official driver takes over the mouse settings, but does not allow you to configure mouse scroll speed, and the setting was too low.

Well that is annoying.

  • Same mouse.That official driver sucks in windows,too

  • SteerMouse is a good replacement driver/CP for scroll, as well as customisable button layouts, on a per app or global basis.

Some 3rd party applications add more settings to control the behaviour of the mouse/trackpad. BetterTouchTool does that, for example.

    Does it really? Because I can't find the scroll setting ANYWHERE?

  • I can't find such setting. I find the lack of a mouse scroll for annoying too!

For me (using Razer ATHERIS - MAC OSX 10.13.4) the solution was...


This made the scroll speed in mac preferences to work:

(I have Synapse running and working to)

Upvote if this work for you so people will know.


I faced with the same problem when using Razer Atheris mouse at Mac OS Mojave. Tried a lot and here's what helped me:

  1. I unpaired mouse at System Preferences > Bluetooth.
  2. Went to System Preferences > Mouse and did Set Up Bluetooth Mouse...
  3. Configured desired scrolling speed at the same window of System Preferences > Mouse.
  4. Got no effect at first, so I did a reboot. It worked!
