I've heard many comments here says they got issues with the Audio and i even heard somewhere you must use in a special supported Webcams and Microphones for Mac?
Can someone explain me please more about it?
Not too sure about webcams, but the microphone input is a line in type rather than a normal mic. so you need a powered microphone with line out for it to work (I think there's some USB devices to do this)
I don't think there will be a problem with the speakers. I have a pair of HP speakers that came with a now retired monitor. They work fine with my Mini.
So wait, What kind of Microphones do you suggest me to get then? Since i'm using my Microphone a lot and i might need one that works on my Mac Mini too. Does anyone can suggest me about good models?
