signal not coming through the direct jack on laptop

i just got a package deal on a ART Tube MP Studio preamp, a generic mic cable, and a MXL V63M condenser mic.

I got a 6ft shielded 1/4" - 1/8" audio cable from Radio Shack.

The mic plugs into the preamp, the preamp plugs into the audio in on my MacBook Pro.

I can get signal coming through the preamp, but not going out into the computer, either to Logic or Garageband.

I’m not sure if it’s the adapter I got from Radio Shack, or the input itself, or what.

This sucks!

Recording with external microphone onto a Mac

That’s how I record everything given differences in equipment here and there.

I’m not sure if it’s the adapter I got from Radio Shack, or the input itself, or what.

Radio Shack part number?
