'Magic' mouse does not scroll

For me, it was simply an issue with the Bluetooth connexion somehow. My Magic Mouse connected to my MacBook Pro was not scrolling even though the trackpad on the MacBook worked. This bug weirdly seems to be triggered by plugging in an exeternal monitor.

To fix, I simply :

1. Click on the Bluetooth Icon in the menu bar
2. Hit "Deactivate Bluetooth"
3. Use the trackpad to reactivate Bluetooth

After that, everything works fine and scrolling is working again (in my case, at least... it could be a different issue for you).

A common trick, if you only have access to your Magic Mouse (and after deactivating Bluetooth find yourself stuck not being able to reactivate it), you can hit spotlight with CMD + Space and find "Bluetooth File Exchange.app". The way this application is built is that it will pop-up a window at launch to warn you that Bluetooth is not activated and has a button "Activate Bluetooth" already focused (in blue). You can then hit "enter" and reactivate Bluetooth quickly without hassle.

Look in System Preferences > Universal Access > Mouse & Trackpad tab > Mouse options.. button > check scrolling.

Hello:

Cutting through your rant........ I am not an apologist for Apple, but no one makes devices that are perfect all the time.

The scroll wheel is a matter of preference. Mine is that not having a wheel is one less thing to gum up and go wrong.

If the mouse is new, either call Applecare with a warranty issue, or take it to a store for replacement.

If you want to try something, reset the SMC and PRAM.

Hello:

is it supposed to actually scroll down the page like a wheel would do when you rub your finger along the top;

It scrolls up and down when you rub your finger vertically. It will do the same for horizontal scrolling when you rub the finger horizontally.

Sorry about the acronyms - I sometimes "assume" things - and you know what that does. 😉

SMC=system management controller - reset like this:

PRAM=parameter random-access memory - reset like this:

Both of those sometimes fix odd problems. Neither operation will harm anything.

I think you need to look at my first post again. Within System Preferences is a section called Universal Access. It's separate from the Mouse options. Within that section is the scrolling option as described above. You stated you couldn't find it but you'll need to.

Edit: I also assume you're running Lion 10.7.x as your profile indicates.

I've been poking about in the forums, and it seems a lot of people have trouble with the mouse wheel stickiing. It is not an issue of Universal Access. It's that the mouse is not well designed. Apple Support suggested cleaning it, which sometimes works but not all the time. Shaking it seems to help. Having it work right in the first placce would be better.

Today, I can track down a page but not up. Excuse me while I go find something to clean it with

Open System Preferences, click on Accessibility, (in System Group) choose Mouse & Trackpad from the left pane, click on Mouse Options and check the Scrolling option. You can also experiment with interia settings which change the behavior of up and down scrolling.

You might note in my original post that I said the problem is not Universal Access. By that you may have inferred that I had tried that route. The scroll button works when it wants to. Just now I can scroll down but not up; sometimes I can scroll up but not down; at other times it was stuck both directions. The lady at the Mac store said to clean it. I do that. I shake it. Sometimes it works. If I have to replace this mouse, it probably won't be with the Apple product. By the way, there is no Universal Access in Mountain Lion. It's simplh Accessibility .

Delete the extension named USBOverdrive.kext in the extensions folder under \System\Library\Extensions. Restart the computer and it work.

OK - a mighty mouse has a scroll ball - a magic mouse has no scroll ball. The confused posts about a wheel or ball when talking about a magic mouse are making me nuts. The genetleman who mentionned things about the universal Access is right.

HOWEVER you must choose "universal access -> mouse -> options" once the MAGIC mouse is operating and in control of the cursor. If you are trying to find this mysterious button using your mighty mouse it will never show up. Universal access is smart enough to know which kind of mouse or trackpad is connected and what options apply.

GO backl turn on your magic mouse then access universal access and rinse and repeat ...

You are mixing magic meese and mighty meese -- a magic mouse indeed has no scroll wheel button, lever, or other physical gimmick. A mighty mouse on the other hand does have a scroll ball which does get crudded up and des occasionally need cleaning -- whihc exact mouse do you have and neither mouse has a wheel.
