I recently got a 2012 macbook pro. A bit later, as a gift, I got a razer sabertooth. When I plugged it into my pc, it didn't work. I tried repeatedly, and then somehow it started working. Then I tried it on my mac. After a while, I googled whether you can use 360 controllers on a mac. When I realized that you can't officially, but you can get some stuff that will let you, I downloaded these two items: http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/OsxDriver http://joystickmapper.com/ All the downloading and installing went fine, but when I plug in my controller, neither the driver nor the app recognize that I have a controller plugged in. I really need help figuring this out, because I really want to use the sabertooth at LAN parties.
