Does Steinberg USB sound card work with new generation iMac?

Hi folks,

I have purchased the new generation iMac (Dec. 2013). It is configured with a regular hard drive and Maverics OS.
Now I need a sound card for it and might go for the Steinberg UR22.
Do you know if it works fine with iMacs? Please keep in mind that there are many iMac users who have experienced massive problems with iMac and sound Cards.

Thank you in advance…
