Topic: RIAA curve in software

I don't know if this is the correct forum but it seems to be the most general.

I have a Fireface UCX and Totalmix software on a Mac Mini.  I input analog audio from a turntable via a balanced line into the two front ports.  Previously i used Pure Vinyl to make the RIAA adjustment but that doesn't work on the latest Mac OS.  I am trying to find a way to make that adjustment with my current setup.  Any help would be appreciated.

Balanced output to Classe Power Amplifier and HSU subwoofers.
