there is no supporting software for older versions of apple operation system

I tried to download "logitech camera settings". It did not work because 10.7 or higher version of the operation system was required. My operation system is 10.6.8 (so close!) I purchased the "webcam serttings" hoping it will allow me to use the logitech camera 920. The installation was good. It allowed me to make adjustments to nothing. The camera still does not work with my MAC.
