I've been playing with this mouse through the weekend, and the one thing that's definitely bothered me (besides lack of middle click), is that this mouse is just too slow. I have the settings in the systems preference panel cranked up to the fastest setting, but it's still not enough. The mouse feels sluggish.

Are there any programs or hacks that will improve this? I've tried MouseZoom to no avail and iMouseFix doesn't work under Snow Leopard.

In Terminal, type:

defaults write -globalDomain com.apple.mouse.scaling -float 12.0

...then logout/restart. You can replace 12.0 with the value of your liking; higher number = higher speed. The slider in System Preferences maxes at 3.0, I believe.

Ha! I had the exact same problem, especially if you have more that one screen to mouse across. The answer is super easy...

MouseZoom:

MouseZoom is a small Cocoa pref Pane which lets you set your mouse scaling preference (mouse speed) to greater values than the Apple-supplied pref pane.
MouseZoom is not a "kernel extension" or driver and is safe to use. MouseZoom does not modify the mouse 'curve', only the scaling. Note that MouseZoom does not work with USB Overdrive.

Intel and PowerPC versions available and it works as promised without any gimmicks or oddities.
Hope that helps.

I had the same issue with the old BT Mighty Mouse. Nice mouse but too damn slow. Looking forward to trying the terminal tweak, Aaron... thanx.

Dave, how does she perform otherwise?

You shouldn't have to hack or use 3rd party drivers to make this mouse function acceptably on a Mac. That's nonsense.

I've found the Magic mouse performs poorly on vinyl mouse pads and better on plain surfaces. Despite this, it tracks way too slow, and scrolls too slow. I'm giving it a week more of adjustment, then will resell it if I'm not happy with it.

A lot of MacSheep think this is a fantastic mouse. It is, if you are moving up from the Mighty Mouse. But if you've had a garden variety wireless Logitech mouse with scroll wheel, you know that the Magic Mouse is not that special, and inferior in many ways.

I just picked this up to try out as a laptop travel mouse. I currently use the Mighty Mouse as my travel mouse, and love it, but thought this might have some nice new features. Researching the slowness problem is what brought me here, and the terminal settings above are a nice solution. I didn't try the application posted above since the manual settings work to fix the Magic Mouse problem. On the other hand, this setting affects all pointing devices, and I use a left-hand trackball when I'm at my desk. Now the trackball is unusable.

The Magic Mouse has promise but this is a show-stopping problem. The Mighty Mouse is fantastic though, so I'll just go back to that.

I've had a Magic Mouse for a couple of weeks and been happy with it, even across my dual 23" Apple Disply set up. Then today is suddenly went slow. I mean r...e...a...l...l...y s...l...o...w. It takes about 20 swipes to cross a single screen and is acting very erractically.

At other times it will only move virtically and not left to right.

Battery level is 75%, all other settings are as I have had then them the whole time.

There is ZERO support on the Apple website or trouble shooting in the documentation that came with it.

Any ideas folks. I don't think I need to use any of the hacks posted so far but is there a way to re-set it?

The mouse feels great in my hand, but that's about it. It lacks the functionality that I had in the mighty mouse, to include middle click which was useful in closing tabs in Chrome. Tracking is still too slow but I've fixed that with Steermouse (now known as MagicDriver). It also plans to include different gestures, for ex: two-finger click for middle-click.

You should check out programs like MagicPrefs or other apps that adds more control options for this mouse. Check out the article that covers several such tools: http://www.geeksology.com/how-to-add-additional-gestures

http://vladalexa.com/apps/osx/magicprefs/ is a powerful tool that can help with this. In addition to attaching actions to various types of taps, clicks, drags, and pinches, including adding middle click, you can speed up the mouse speed extra.
