I have a MacPro mid 2010 model, and I'm running El Capitan. Is this compatible with El Capitan?

I'm all windows 10 now. These will probably work though. New os systems tend to provide drivers automatically for these kind of add ons. I have no direct experience with El Capitan and this card though.
