My mic doest work =/ help?

Could just be a Mono mic. I dont know to much about sound engineering, But that definitively could be it.

What connector is it at the end?

Most mics only do 1 channel. Software can double it over to the right channel.

It is a monaural microphone. However, if you check the users manual on page 4, it shows how to control the mic, and figure 4 on that page shows a control for balance, meaning you can move the sound all the way from one side (channel) to the other, and anywhere in between.

This is not true stereo, since real life sounds from straight ahead or behind reach both ears simultaneously, but the sound from one side or the other arrives slightly sooner to one ear than the other, and the brain will calculate the time differential to place the direction of the sound, the farther to one side, the greater the difference. There will also be a slight attenuation of the volume on the farther side. The balance control will only make one side louder than the other, but not displaced in time, so fooling your brain into thinking the sound is more on one side due only to the difference in volume based on how the balance control is set.

A stereo microphone will provide individual signals for each of two channels, the strength and timing of each determined by the direction and distance of the sound from the microphone. One drawback is that with stereo microphones, the two pickup surfaces are usually closer together than the distance between your ears, so they don't sound truly realistic.

For the most realistic effect, there are binaural microphones, not only set the correct distance apart, but set either on a dummy head with molded ears, or worn on a real person's ears, so each microphone capsule gets the sound bounced from the irregular shape of the ears, exactly like human ears hear. The recording then has to be listened to using headphones, not speakers, so each ear only hears what it should, not as with a stereo setup where each ear hears both stereo channels.

The difference is astounding, sounds absolutely three dimensional, but the binaural experience is not practical for anything but private listening.

What program are you using?

On the Mac, have you tried the included GarageBand (one of the iLife programs)? If you haven't, it is very versatile for making simple audio recordings with a mic or several inputs either all at once, or one track at a time. Even professionals use it, as well as small and not-so-small bands that want to do their own recordings.

Nine Inch Nails for example have posted some of their music in GarageBand format for fans to play with and remix for fun.

For each input there is a rotary dial marked with "L" and "R" to control the position of the sound. There are 128 positions to place the mic or other instrument precisely between the fully left or right channels.

Since my last post was so big, I didn't want to confuse the issue, but where the example in the manual calls the control "balance", the industry jargon calls it "pan", the same word as in film and video where you turn the camera from side to side.

You can fix that in Audacity. Simply open the audio file in Audacity, click on the arrow towards the left of the audio waves (above where it says "Stereo 8000Hz") and click "Split Stereo Track." Then click the X on the top left corner of the blank side, then click the arrow towards the left again and click "Mono" and save.
