Program my Logitech M545 Mouse for Mac I am currently using Logitech M545 Mouse, which has two side buttons for convenient operations under Windows.

In windows, one button is for displaying the desktop, and the other is for Start button. I find it really convenient. Logitech claims that one may program the uses of the two buttons for personal use.

Now, I am using it together with my MBPR late 2013, and the two buttons do not work any more. Is it possible to program it so that one button is still for displaying the desktop, and the other open the Application Center?
Mac-compatible Logitech mouses come with a preference pane to program their features.  Or (even if not Mac-compatible) try a third-party mouse-button utility, like SteerMouse, $20.

Here is the post about using the Logitech M325 on Mac.  Maybe that will work in other cases, too.
