I recently bought an iMac and after i have started computer, i have realized the mouse is moving too slow. I have a wireless mouse. After i have searched in System Preferences, i have found the
Mouse option and i accessed.
After you enter in Mouse menu, drag the
Tracking bar maximum to the right.
Even in this case, with mouse sensitivity set at maximum in system options, the wireless mouse is not moving fast enough.
Instead buying a software that enable other options to increase the mouse speed, i have bought a normal USB mouse and is working perfectly now.
