Alesis iO4 interface with Cubase 7

I’ve been using the Alesis iO4 audio interface on a Toshiba Satellite w/Windows 8 with no problems. I recently acquired a Mac and now the interface is not wanting to work properly with Cubase. Static is all I get. However, the interface works fine with GarageBand, which tells me that it may just be something within my DAW that needs to be adjusted. Any idea as to what the issue could be?
