hey guys I'm relatively new to Mac as I just purchased a refurbished MBA 2013. The one problem that I seem to be having is the tracking with my marathon mouse M705. It just doesn't seem to be as smooth on the Mac as it is on my PC. I have adjusted the tracking speed to a fast setting and wondering if anyone has any advice. Is there anything else I can do or anyone have similar problems? I'm thinking that it may just be an adjustment that I have to get used to. Any advice would be helpful, thanks!
