macOS is a family of operating systems developed by Apple and exclusively available to Apple's own family of personal computers known as Macintosh (or Mac for short). Although there are certain 'regular' PCs that can run the operating system (know as 'Hackintoshing') it is highly controversial due to violating Apple's end-user license agreement and being notoriously inconsistent in its results.

The family is separated into two distinct series:

• The Classic Mac OS (System Software) series that consists of operating systems released between 1984 to 2001, starting with System 1 and ending with Mac OS 9.

• The modern macOS (previously Mac OS X and later OS X) series that consists of operating systems released between 2001 and today, starting with the release of Mac OS X 10.0 and continuing with a new 10.x release every couple of years. Instead of being based on the Classic Mac OS, the series traces its roots back to NeXTSTEP which itself is derived from UNIX. This series of the operating system is also the basis for iOS as well as its other siblings in Apple's product lineup. The series was rebranded from Mac OS X to OS X in 2012 and to its modern name macOS in 2016.

The original Macintosh was released in January 1984, and was one of the first systems to pioneer the graphical user interface (GUI). Prior to its release, Apple had three series of command-line driven terminal computers known as the Apple I, Apple II and Apple III. These systems were not compatible with the Macintosh and should not be mistaken with it. Apple additionally had another graphical driven system prior to the Macintosh called the LISA; again also not compatible.

The family of operating systems are one of few platforms to have survived moves to new processor architectures, with a move from Motorola's 68k to IBM's PowerPC in the mid 1990s, followed by a move to Intel in the mid 2000s, and a move to ARM during the early 2020s.

Newer versions of the operating system still makes use of OpenGL 4.1 from 2010 and with the release of macOS 10.14 in 2018 Apple officially deprecated support for the standard in favor of their own Metal API.^[1] This move resulted in a large lack of recently released major games on the operating system.^{[citation needed]}

Modern versions of the operating system does not have support for the Vulkan graphics API, however developers can utilize MoltenVK in their games to translate Vulkan calls into Apple's Metal API.

The link to the program is bad. The url for macosxhints.com was appended to the start of it.

Anyway I have to admit I have not noticed this acceleration curve (and still don't). I feel weirdly sheepish admitting this as it seems to bother others a fair bit but there you are.

Don't feel bad, I haven't noticed it either... :)
I have a MS IntelliMouse Express 3.0 USB Mouse (have not installed any drivers, just plugged it in) on 10.4.2 on a 15' 1.25Ghz Al PB.
I don't notice it on the trackpad either though.
I have my mouse settings set to 'Fastest' as well. Maybe some combination of the above eliminates the problem as well.

Better late than never :)
Using Mighty MouseLogitech tracking set to Fast(est) and on dual monitors - I notice it big time, but if set to default its not as noticeable. But I want to go to 'fastest' so that I can move the mouse from corner to corner without having to move my arm.

I for one HATED the current acceleration curve. 'Brick wall' acceleration is a good description. It is nothing like older (OS 9?) acceleration curves.
I use two programs to fix the problem. MouseZoom (it only changes the overall rate, not the shape of the curve) and a feature included with SideTrack called 'Redmond acceleration' or something like that. With Redmond turned on and the MouseZoom at around 2.5 I'm a pretty happy camper, but I'm extremely interested in the solution offered here, partly because SideTrack is a kext, although I don't think it has ever caused a problem.
Please, I wonder if the author could make this a little less UNIX-y? I think the potential audience for this is significant if it were posted on versiontracker.
Suggestions
Make a pretty interface so use of the terminal is unnecessary. Include a table in which the user can enter the data pairs. Even better, make a little graphical display where the user can click to set the points, with a line connecting the points.
Describe how it works in the ReadMe—does it patch running code, a plist, or what? (Does the user need to worry about crashes, for example). (Why are there two ReadMe's and the first one is blank?)
Explain if the thing continues to use cycles after the set-up program is done.

How do I reset the parameters if I didn't like the new ones?

This actually works ! I've tried everything to change the behavior of my mouse in Mac OS X. Nothing worked, yet. Because I use Windows at my work I'm used to the quick response and no acceleration of the mouse. MouseZoom speeds up the movement of the mouse but doesn't change the acceleration curve. USB Overdrive helps a bit but not 100%.

How do you turn this thing off. I did it and now i hate it. Someone please help!

SteerMouse (http://plentycom.jp/en/steermouse/) solves this problem by letting you disable the mouse acceleration.

Microsoft have released the Intellimouse drivers for OSX. If you've got a MS mouse these may help.

I never cared about the mouse acceleration either, UNTIL I just got a mouse with a scroll wheel... the acceleration on the scroll wheel is almost making the damn thing useless to me.
You move the 'scrolling speed slider', and the slow-scroll never changes, all that changes is how quickly it accelerates (rate of wheel turning vs. rate of page scrolling)... very un-intuitive, and very irritating.
I was really hoping there'd be a com.apple key or prefs file i could simply type 'Acceleration=0' into or something...

This seems to work ok in Leopard. I'm using his version 1.1 (command line). Thanks for making this. I just 'upgraded' to a mightymouse and on a big monitor the acceleration/deceleration was driving me nuts!

works like a dream on 10.5.6. so much better. thx.

I used compiled version 1.2 (acceleration factor 2,5) with touchpad of MBP (late 2006) with both OS X 10.4.11 and 10.5.6. It works like charm.
The cursor movements behavior is very close to Windows XP.
Thank you.
