My 2013 iMac is playing sound out of my shure sm58 microphone, instead of allowing me to record into the computer
I bought a shure sm58 microphone and a headphone jack adapter because the the microphone cord is designed to be plugged into a dj turntable, my iMac is recognising the microphone as line-out and playing audio out of the microphone instead of allowing me to record into the microphone.
iMac, OS X Mavericks (10.9.5)
