Magic Mouse scrolling doesn't work.

System Preferences > Mouse > Point & Click?

Same thing happened with my mouse once I updated; anyone have any ideas on what could be going on.

System preferences only gives the option for tracking speed and double click speed no scroll option.

It is hidden in System Preferences:Accessibility:Mouse & Trackpad:Mouse Options

Just tried that and my mouse still doesnt scroll. Any other ideas?

Take batteries out of mouse and put in again/restart Mac?

Done and done but still isnt working I dont think its the mouse I think it is a software issue. Waiting to hear back from apple care and will post any answers I recieve.

Yes, very odd - mine is working fine so can't help further, but will be interested what the solution is. Do you have a trackpad as well as the Magic mouse?

Mine didn't work either. Frustrated.

Add me to the list of frustrated Mountain Lion upgraders... I tried the PRAM and SMC resets and that didnt work either. I did see that the Accessibility pref did have scrool speed under 'Mouse Options' but that didn't help either.

I can't imagine this is a minor issue or an intended design.

I have tried everything recommended here, as well. Can't use any of the finger swipe or scroll functions on the Magic Mouse after upgrading to Mountain Lion. Was fine before with Lion.

P.S. I just spoke with Apple Support, which said that it is a known issue that they will try to have fixed in the next update----about a month. Nothing we can do until then. They say they have the finger gestures working with the trackpad, but not the Magic Mouse.

Here is the fix worked for me, hopefully it works for you guys.

System Prefs -> Accessibility -> Mouse & Trackpad -> Mouse Options... -> Checked Scrolling

Best,
