You need a line-level mic. You are using a mic-level mic. Line-level audio
equipment signals are much stronger. Your personal stereo outputs a line-level
signal to your headphones.
If you have a portable mixer that outputs a line-level signal, you can attach
the mixer to the mic. and attach the other end of the mixer to the mac.
I should work fine.
But otherwise, I'd just go out and buy a line-level mic.
