Barebones Recording Options

[Vard]

Here's my problem...

My brother has been bugging me to get my Mac ready for recording...I could really care less due to everything else I do on it not really leaving me time to record anything right now. So, for him, I will turn to you for assistance.

I have a DP 1Ghz QS (spring 02) with the lastest in both OS's. I would prefer to stay in OS X if possible. I need advice on software and any hardware that one might need for this endeavor.

Let me say, while my brother is a dreamer, he is definately NOT a financer...so I am, seriously, looking for the barebones of what I would need to get audio into this thing. For arguments sake, and I realize this may go against the whole 'barebones' thing, it would be cool to have multitrack capability, even 4-track would be fine. He is looking to record guitar and vocals.

Anyway, that's my problem. Any help with this would be great. Thanks for the help.
