Scrolling acceleration in Mountain Lion?

http://www.apple.com/feedback/

Get posting feedback on this people! This needs a setting, even if it is a hidden one for power users.

I'm getting fed up with Apple tweaking the mouse so aggressively and providing zero options or fallbacks for those who prefer previous behaviors. I'm not sure if anyone who could alter this ever reads the forums so it's better if a good few of us post it to the OSX and Magic Mouse teams

Hi all,

I found this:

It seems to work for me. I hope this helps.

Ciao,

Perfect! Finally.

Thanks, for the temporary fix, hope apple soon has a fix for it.

Great temporary solution. Thanks a lot! 🙂

Thank you Lordlukas,

To repost the link which "fixed" the issue:

https://github.com/davekeck/DisableExtremeScrollAcceleration

The disabling is now successfully enabled. 🙂

Thanks !

It was really annoying !

And how would I reenable scroll acceleration (just in case)?

Can this be synthesized in 1 command line?

this sounds like the issue i am having. if i want to scroll faster i will just flick the trackpad multiple times. and usually i can see what's going on. After the upgrade to mountain lion. The same kind of movements skips over content that i wanted to see. it worked like a book before you could see where you were going. now you can't and it's annoying.

apple please fix this.

you know i think this is a bug.... not a feature.

it used to only go into extreme scrolling mode when you flicked it that many times.

but i tend to accurately scroll and stop. scroll and stop. and it's doing it after you stop. when it shouldn't

I'm experiencing a similar scrolling problem with my Mac wireless mouse in Google Maps, and also Mapquest. When trying to move around the actual maps feature such as satellite views, the whole works goes crazy when I barely breath on the mouse. Trying to do work arounds with a few mouse moves actually makes things worse. This is not a new problem with this device, as it did the same thing in Snow Leopard (currently using Mountain Lion). I do not have problems on any other sites. It's just taken me until now to research a little bit, and find out if others are experiencing similar problems. I'd sure enjoy hearing any suggestions to fixing this situation, other than reverting back to a hard wired dumb mouse.

I agree, it is extremely annoying with the exponential scroll acceleration. Don't have a permanent fix for it though.

It is extremely annoying, but thankfully there is a fix, as posted above:

https://github.com/downloads/davekeck/DisableExtremeScrollAcceleration/DisableEx tremeScrollAcceleration.zip

Just download and run the app and voila!

If you want it to be permanent, just open System Preferences, click on Users & Groups, then Login Items, then just drag the app into the list (labeled "These items will open automatically when you log in").

And if you ever want to undo the fix, just remove it from the Login Items list and restart your machine.

Note for the technically inclined: If you want to compile it yourself, all you need is to create an Xcode command-line tool using the "Foundation" setting, add the IOKit framework, then replace main.m with a few lines of code from here:

Thank you to those who found this fix.

+1 need to be able to adjust scroll acceleration speed. I'm using an external trackball with a scroll wheel.

My problem seems to be happening with the pdf viewer in safari. When I open a pdf that way the scrolling is out of control. Otherwise I think I've mostly adapted.
