I plugged in my microphone into the mic port on the left side of the computer. Im trying to use it for my Ustream feed but it is not recognizing it. Does anyone know how to fix it? Thanks.
The port next to the headphone jack on your macbookpro is not a mic jack it's a line in jack. The difference is that the mic jack apply a little power to the mic to pic up the signal, you going to need to buy a USB mic or USB sound card.
That's not true. The port IS a mic/audio in jack. The OP's headset should work fine, since it's also compatible with MP3 players. No extra power is needed.
To the OP: This may sound ultra-basic, but make sure you're plugging into the mic/line in jack, not the headphone/line out jack. You'd be surprised how many get tripped up by that.
The port is line in. You need to amp it in order to make it work. Normal microphones do not work.
In the end, I got a USB mic.
http://support.apple.com/kb/HT3628The port is line-in. Not mic-in. I did extensive testing about this and ended up using a USB mic.
Audio line in/optical digital audio in port: Connect your MacBook Pro to a line-level microphone or digital audio equipment.

"Mic signals are low voltage signals produced when the sound ways vibrate the mic diaphram. They range from about 1.5 millivolts in a dynamic mic to maybe 70 millivolts in a really hot (read: sensitive) mic (based on a reference sound pressure level). These signals are delicate and are easily corrupted by electrical noise. Line level signals are much stronger (higher voltage) and are basically an agreed upon industry standard of about 750 millivolts. Using line level signals enables various different devices from different manufactures to be interconnected. They also can be carried over longer distances.
Mic signals are also characterized by their impedance, which affects how efficiently power (remember these are tiny delicate signals) is transferred from the mic source to an input of another device (usually a microphone preamp that raises the signal to "line" level). High quality mics have low impedance and are bests used when coupled to low impedance inputs (low impedance means the current flowing is higher, and the signal therefore has greater noise immunity). Consumer mics often times have high impedance (Hi-Z) and are coupled to Hi-Z inputs. Hi-Z signals are more readily affected by noise."
