ur824 installation with Mac troubles

Hi I just purchased a new macbook pro and a ur824.

I am trying to install the elisence key and its giving me a error that my OS is out of date that it needs Leopard 10.6 or greater…

I think my OS is OS X 10.10?

Again this is my first Mac, Ive been on PC for years, so Im not even sure where to go to confirm my OS… I did all the updates to the Mac and Im sure its up to date…

Any ideas and thank you!
