Inverted scrolling for external mouse I have an external microsoft mouse for my iMac. When I updated to Mavericks it inverted the mouse scrolling but I can't change it back. The mouse has a specific program that controls preferences within system preferences so changing mouse controls to "natural" within system preferences does nothing and the program has nothing to control this setting. The mouse uses bluetooth to connect to a usb connector so I can't connect the mouse directly through bluetooth mouse. How can I change the settings back to normal?
The "natural" scrolling is reverse of normal scrolling on a laptop. Switch off natural scrolling and let us know if that works.
