you're welcome.

even Audition leaves artifacts if not used very, very carefully. nr has come a long way but unfortunately there's no magic bullet when it comes to this technology.

my best advice is to pick up a used pc somewhere, for around $1,000 you could get an operable pc setup with soundcard and Audition. With pc you also get access to hundreds of freeware (and often free software) VST plugins that aren't available to mac users. It seems almost every mac user I know has a pc hidden somewhere in their house, they really come in handy from time to time and you can still use your mac for the majority of things.
