Hardware playthrough is a problem on Macs, and generally most basic
USB recording interfaces won't give you hardware playthrough anyway.
Have you tried Audacity Beta, or are you already using it?

You'll probably need to invest in a more specialised interface such as:
http://www.m-audio.com/products/en_us/FireWire410-main.html

that supports low latency software- and hardware-monitoring, and use 
a recording application that supports the required ASIO low latency
sound drivers. Audacity does not, unless you compile it yourself from
source code.    

I've heard that some people with keyboard instruments that have a
separate audio out (so they don't have to use headphones out to send 
the audio to Audacity) manage by playing the previous tracks softly    
and listening to what they are recording through the instrument 
speakers. 

You might also want to try our Mac forum:

as one of the regular contributors is on Mac and may be able to make
recommendations.
