how to disable headset microphone and enable macbook built in mic?
on logic (music software) with normal headphones plugged in i can still use the laptop built in mic, but with these new ones that have a built in mic in the headset, it automatically disables the built in laptop mic. how do i disable this and only use the laptop mic whilst the headset is plugged in?
MacBook Pro, OS X Mavericks (10.9.4)
