I need a simply jack Mic unamplified physically connected to my Mac Mini (late 2012 model) through Audio-IN and it doesn't work.
I also tried the original iPhone's headphones to no avail and I wonder if this is normal?
Does the Mac Mini require a USB microphone or can I use the Audio Line-in port with another type of microphone?
UPDATE 10/14: I tried using a 3 channel splitter like this
then I plugged my speakers and my earphones with mic but nothing to do, mic still doesn't work... (maybe just because this splitter has a 3 channel male jack but it's a normal 2 ch; I bought it for 2€ from China so it's possible..)
