I have a MacBook Pro (Retina, 15-inch, Mid 2014) and a Logitech M545 mouse. The mouse is not recognized in Logitech Control Center, and when I uninstalled the Logitech Control Center, and installed USB Overdrive, I can reprogram left mouse button, right house button, and scroll wheel click. I cannot program buttons 4 and 5 on my mouse, which are on the side of the mouse. To the software, they aren't even there. Can someone help address whether this is a mac issue with not recognizing buttons 4 and 5? Thanks in advance.
