Any idea why I am unable to scroll up and down in Safari and in other applications using the laptop's trackpad? I have to move the pointer on top of a scroll bar, click and hold with one finger, then scroll with another finger. Looking to scroll pages without dragging the scroll bar.
I have already checked the Trackpad settings in System Preferences.
Thanks.
MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)
Seems to have fixed my issue! Many thanks. 🙂
I have spent HOURS trying to solve this problem. The terminal command did not work for me, even though I know it did for many others. And an hour on the phone with mac support was no help either.
The problem is your trackpad preference files. They are corrupt and need to be removed.
Go to the finder> library and the preference folder.
Then find and delete the following files
com.apple.AppleMultitouchTrackpad.plist
com.apple.driver.AppleBluetoothMultitouch.trackpad.plist
Restart your mac and the two finger scroll will instantly work again.
this did not help me, actually - what worked for me was to go to Accessibility; select mouse/trackpad, select trackpad options and turn scrolling "on".
I switched it back off and trashed the prefs as you suggested but it didn't help, so Im back to "scrolling on" in the accessibility pref pane.
Just an FYI, your mileage may vary.
Just turn off Safari and reopen.
