I have a new 27" IMac with all updates installed. I use Track pad and wireless keyboard and wireless number pad. No Blurtooth in the house . Bluetooth boards replaced. Nearest neighbor is several thousand feet away and not home during the day. When using Sarafi the screen will rapidly scroll to the bottom and stay there. It might be anywhere from 30 seconds to several minutes until I am able to scroll back to the top of the page. During this time I can't get any of the bookmark folders to stay open although  if I do not take my finger off the track pad I can hold it open. Some times I have to reboot Safari to reset the page. This happens on an intermittant basis and it may be days between occurences,

Is this a know bug in either bluetoopth, Safari, or the OS?

Genius Bar at the store says its interference but I can't find any.


Aperture 3, Mac OS X (10.7.2)

    The same symptoms will occur if the keyboard spacebar is intermittently stuck.   You could check for that by starting the keyboard viewer so you know what keys are pressed. 

     

    System Preferences > Keyboard > Keyboard tab > check "Show keyboard & Character Viewers in the menu bar".

     

    Then in the menubar, show keyboard viewer.

    Click the new icon and select keyboard viewer.

    OK  now I just leave that up ,off to the side and see what is happening when the magic scroll strikes. Is that correct? Is there a fix for the spacebar causing this?

     

    I didn't see the new icon and didn't know it was called the menue bar  new to macs

     

    Thanks

    Correct.   You could also test by holding the spacebar down to compare results to your symptoms.

    Is the keyboard supposed to do this or is that a reported bug?

    Not a bug that I know of, it could be a physical keyboard issue.  Maybe worn out/sticky/defective.

     

    The browser is suppose to scroll down when the spacebar is pressed.

    And scroll up when you press Shift-Spacebar.

    A few months ago, I bought a new desktop iMac. (After using a Mac for 22 years, I'm pretty disappointed for several reasons.) I have experienced the runaway scrolling issue. For example, on FB, the page will scroll downward throughout all the old posts on my news feed. Another quirk is that while scrolling, the window I'm in can start zooming in and out, then it stops on its own. When this happens, scrolling up or down controls whether it zooms in or out. It will stay zoomed in or out even after rebooting.

     

    I've read several complaints about this issue, and I want to add my stats to yours and help eliminate as many things as possible. People are questioning their mouse or software, and desktop models vs. laptops. This seems to be a equal opportunity bug, though. When I bought this Mac, I chose the old-fashioned corded mouse and the big corded keyboard, so don't blame your fancy mouse or wireless. That's all I have.

    Following all this above advice I traced the problem to my wrist cushion. When I need to use my bifocals while working on pics I have a tendency to lean my left forearm on the 3m cushion. This caused the gel cushion to swell out at the exact spot that would push down on the space bar. Because I never had an apple before I didn't know about the scroll short cuts. Of course the new bluetooth board and new keyboard didn't solve the problem. The keyboard viewer showed the problem and the solution was to stop leaning on the spacebar.

    As I was telling my friends yesterday, I've read so many comments, similar to yours, trying to get a handle on this problem. None of our would-be causes or cures stops this from happening. I have no wrist cushion, never use the space bar to scroll. (I'm sorry you just now got your first Mac, because, unfortunately, they aren't the way they used to be. I think Apple is way more focused on their hand held devices.) ............ The only thing that seems to get me out of the scrolling problem is to keep hitting the 'esc' key over and over until it stops. I had it happen earlier today and that made it stop pretty quickly.

    I'm sorry too. My son talked me into this for photo work. Aperture was the bigest PITA ever. now I have LR4.1 Macs sure are quirky.

    Macs used to be so much easier. That's why there are so many of us Mac fans. I happened to buy a new one (after 22 years of using a Mac) and enden up with this thing that I can't relate to at all. After looking around on my new Mac (and freaking out), the first thing I did ... and what you should do ... is use FireFox as a browser. Safari is crap. FireFox also gives you spellcheck wherever you go.

    I have a wireless keyboard and magic mouse.  I have the keyboard viewer up and see that WITHOUT MY TOUCHING THE KEYBOARD the viewer shows that the down arrow key is periodically depressed.  As a result the screen scrools, it scrolls through menus that I have activated with my mouse, and when I was watching Youtube decreased the volume all the way.

     

    I have not gotten any warning that my batteries are low.  Any ideas?
