Software for Mac?

Hi all,

Here's my dilemma - I work with a singer who lives around 6 hours drive away from me; he has a decent mic (Samson CO1 with phantom power) but no means of recording, and we can only get together once every 3-4 months (I use HS4-XL). He's a graphic designer and so uses only Macs - can anyone point me in the direction of any software which will work on Macs, very simple, audio only, no MIDI needed, 4 - 8 tracks would be plenty. (oh, and soundcards - I have no idea what would be needed for a Mac)

Appreciate any help, thanks.

James

Thanks David, basically Tim (the singer) just needs the ability to record vocals and harmonies to a click track so he can send me .WAVs to import into Home Studio.

Audacity looks fine, as does Garageband, so thanksagain, I'll delve into those a little deeper.
