I am new Mac user and I don't really like the Magic Mouse so I reverted to a good old 3 button mouse with a scroll wheel.

When I turn the wheel slowly, it only scrolls pixel per pixel (or per two pixels) If I turn the wheel more quickly, it scrolls nearly line by line. There is a kind of scroll wheel acceleration where the amount scrolled for each wheel step depends on the rotation speed of the wheel.

This behavior is not present in Windows where you always scroll a few lines per wheel step.

Is there a way to disable this behaviour or to tweak it in Mac OS X Lion?

  • Does the mouse's vendor have drivers/software for OS X? For example, Microsoft's Intellipoint mice come with a System Preferences pane that allows you to tweak scrolling speed: i.imgur.com/GJ4SM.png Commented Aug 26, 2011 at 10:50

  • If Chrome is your main browser you can use this extension to add this feature to chrome. However, with this extension enabled you should only use the mouse to scroll in lion. No magic mouse or magic trackpad.

    This behavior is really annoying. Seems like Apple wants to discourage people to use mice instead of his trackpad... Commented Mar 6, 2013 at 11:00

Hope you're still reading - I highly recommend one of the third party mouse managers like SteerMouse or USB Overdrive or ControllerMate.

I found the arch of the Magic Mouse just too low and went back to the old reliable Logitech MX Revolution, but I will never install Logitech software again without an excellent reason. These packages will let you configure all of the buttons and SteerMouse (haven't verified for the other two) will definitely let you specify linear or accelerated wheel scrolling with variable degree of acceleration.

    I'm also new to MacOS. I totally agree we should never install contructor drivers for this kind of device. But I'm used to opensource softwares. Is there really people buying applications for tunning their mice (in Apple world) ? Commented Mar 6, 2013 at 10:56

    I bought SteerMouse. As a developer I am happy to support another developer who makes my experience better. Open Source is a fine idea, but sometimes you just need one guy with a vision.

    Shrug. You see some value in it but won't pay for it? Use inbuilt preferences or install the vendor's drivers - you paid for those with the hardware.

After many years of frustration with macOS & wheel mice, I've developed Smooze. Disabling the scroll acceleration and setting the number of lines you want to move on each tick are free features.

  • Hi bro, what are the exact settings needed to make scrolling on Chrome identical to that of Windows? Would be great if there's a checkbox where the user can just tick to make it work like as per Windows...

USB Overdrive changes the default scrolling behavior so that single ticks of a scroll wheel scroll in larger increments.

It also has an option to for example make a single tick always scroll a single line. It also supports changing the tracking (but not scrolling) acceleration, like SmoothMouse or MouseAcceleration.prefPane.

    This works well, but it is "beg-ware" on bootup and whenever entering the dialog above, and costs $20 to register.

There is now a free program called DiscreteScroll - https://apple.stackexchange.com/a/262329/221420 - it will make it so that one mouse wheel tick scrolls 3 lines.

https://mousefix.org/ -- Try this, I was facing the same issue. Sometimes wanted to use trackpad and a normal mouse together. It has a setting "Invert Direction" too. I am sure you will not go anywhere else after using this.

I am on mac Mojave 10.14.6. Its FREE!

If you have logitech mouse then you can try installing Logitech Control Center for Macintosh® OS X http://www.logitech.com/en-us/support/3129?section=downloads&bit=&osid=35

    That let you tweak the mouse cursor acceleration, not the the acceleration of the scroll wheel Commented Nov 27, 2013 at 1:27

The open-source MOS tool is a lightweight tool used to smooth scrolling and set scroll direction independently for your mouse on MacOS.



System Preferences---Mouse

There you can speed up the scrolling speed.

Tracking Speed relates to how fast the mouse moves across the screen.

Good Luck!

    I'll do it. Acceleration is, in this context, when the mouse cursor (or page, when scrolling) moves farther when you move your finger faster. For instance, as @thieum said in the original question, "When I turn the wheel slowly, it only scrolls pixel per pixel (or per two pixels) If I turn the wheel more quickly, it scrolls nearly line by line. There is a kind of scroll wheel acceleration where the amount scrolled for each wheel step depends on the rotation speed of the wheel."

SmoothScroll for Mac fixes this problem (you can disable acceleration or give your own parameters). Even better it makes scrolling animated between wheel ticks so you get a smooth experience.

By paying for it you ensure that there's somebody out there who cares about the mouse scrolling experience on Macs.
