So I've had my Mac for a few months now. It came fitted with the wireless mouse and keyboard. When I open a browser be it a web browser or a window in finder or any other app and it has the option to scroll down, then the computer will do so. It just seems like the scroll down option is always on. At first i thought it had to do with the mouse, so I plugged in a diff mouse and that didn't work. Also tried changing the keyboard and that didnt work. I also tried deleting the cookies and history from both safari and firefox and that didn't work neither. Any help?
