Macbook ASIO Input

Hi,

I just bought a macbook (I am new to mac) and I am attempting to use my Cubase LE software, but when I use Cubase it tells me there is no input, and that I need to set it.
I try to set the input in Cubase and it says there is no ASIO input.
The mac sound input shows a built-in internal microphone and a line-in/audio line in port. Switching between these two had no effect on the "no input" response from Cubase.

The macbook says on the box: "Optical digital audio/analog audio input and output ports" which I thought had me covered in terms of audio input and output in general... but now I think that that may not be the case.
Is there no audio input on this computer that will run the cubase?
Is this a sound card issue?

I am not the greatest with computers so any help is greatly appreciated!

okay.

so by audio interface you mean, for example, my presonus firepod?
that makes sense... maybe it just did not recognize it.

I'll give it a go when I get home from work.

Thank you!
