Mac Mini + Mic

[Hammie104]

Can anyone tell me why a analog mic plugged into the back of a mac mini will not work? Everything I've read suggests that I need a usb mic or the Imic. Why is the jack even there if it will not support a mic? Struggling to understand this one...

Line-In vs Mic-In... Mics need preamp to be plugged into the Line-In port
