record on a mac book

[mgkmuzik]

hey..ok here is the situation...
1. i used to record with a pc, mixer and mic, the mixer and the pc where connected with an rca wire 2 outlets white and red....now that ive moved to la i got me this mac book but dont really know how to connect the mixer....is it possible? if not what else should i get to connect the mic

2. got logic on my mac now..but for some reason when i hit record it ony plays but the recording doesnt get captured..does that have something to do with the soundcard?? do i need to buy a soundcard?? or what is it?

would really appreciate it if someone could answer me these 2 questions.
