two finger scroll doesn't work.i
Posted: Oct 15, 2008 8:54 PM
 

just got the new macbook. all of the multi-touch gestures work, except the two finger scroll. of course, the most important one doesn't work. anyone else having this issue? i installed all of the updates, restarted, still no luck. pretty annoying. otherwise, a great machine!

I just created a clean account on the MacBook, and the two-finger scrolling works. So I think the account I created when I migrated my files over has some kind of issue with the preferences.

I have the same issue. Just bought a new MBP and 2-finger scrolling was working. I synced my preferences with iSync, and now it doesn't work, and I can't find a way to get it working. If I create a new account it works, but as soon as I sync with iSync, it doesn't work again. My other computer synced with iSync is a 2004 15" PowerBook G4 which doesn't have 2-finger scrolling.

Any help would be appreciated - like, what preference file to I need to delete.

Thanks,
Robin

I suspect the item is com.apple.trackpad.scrollBehavior in the file ~/Library/Preferences/.GlobalPreferences.plist (the dot means the file is hidden by default). It's set to 1 on my 1st gen Macbook.

Maybe someone with a working two finger scroll on the new MB could run:
defaults read ~/Library/Preferences/.GlobalPreferences.plist com.apple.trackpad.scrollBehavior

After playing the "delete a .plist file and see what happens" for about 90 minutes, I gave up and just moved my entire Preferences folder to my Desktop. The issue cleared up as expected, and I've been moving .plist files only when I notice that my preferences need be tweaked. So far, I haven't triggered the two-finger problem. Over the last four years a lot of plaque has built up in that folder so a deep cleaning was probably in order anyway.

The domain/default pair of (.GlobalPreferences.plist, com.apple.trackpad.scrollBehavior) does not exist

Same problem here... migrated from Powerbook G4 to Macbook Pro... all gestures except two finger scrolling work as expected.
Anyone have a simple fix for this? A little nervous about randomly deleting preference files... will I mess something up?

Has anybody figured out what preference needs to be deleted yet? I also migrated my accounts and am unable to get 2 finger scrolling working. After creating a new account it worked in the new account. I am seeing this on a MBP.

Really glad I found this discussion because I've had the same problem with the 2-finger scroll not working on my new MacBook. I too synced the preferences file using MobileMe & this is the only gesture not working with the trackpad. I too figured it was a preference file, especially since I formerly used sidetrack and xscroll so I thought they might have screwed it up. I've deleted every preference file I can think of that might have something to do with it but no luck so far. Hopefully someone will find out the answer soon & post it here. I'll be sure to do the same if I find out first.

I had the same problem on my wife's new AL macbook. I'd done a system migrate from her old iBook G3 running tiger. What I ended up doing was the following:

Create a new account w/ admin privs
log into that account
From terminal (remember replace <youruser> with the appropriate dir):
sudo cp /Users/<youruser>/Preferences/.GlobalPreferences.plist /Users/<youruser>/Preferences/.GlobalPreferences.plist.bak
sudo cp ~/Library/Preferences/.GlobalPreferences.plist /Users/<youruser>/Preferences/.GlobalPreferences.plist

Log back in as the problem user and two finger scroll should work. From here you can delete the admin account you just created.

As a side note, com.apple.trackpad.scrollBehavior was set to 0 on the original file, but there were many other different variables so I decided copying over a working version would do just as well.

Yes, this description did the trick at least for the two finger scrolling on my new aluminimum MacBook. Don't forget however to add "/Library/" before the "/Preferences/" folder otherwise it won't work.

However the three finger going back and forth in browsers for example, still doesn't work. anything else one could try?

After playing around and reading Enoch's http://discussions.apple.com/thread.jspa?messageID=8296244#8296244 reply above, I also decided to copy my old Preferences folder to a different location and start my MacBook Pro experience on a much more reliable base.

After years of use and many upgrades (rather than clean installs) the preference folder was filled with dreck - files with random characters, empty folders, etc. Corrupted preferences also are the cause of most of the instabilities I have had to deal with over the past year.

Keep the old preference folder around and copy specific preference files into the new preferences folder for apps like skype, ical, mail and ipulse which require a lot of tweaking to get right. I also rename new preference files before overwriting them.

Try spreading your fingers apart a little bit when doing the 2-finger scroll.
