How to use Neewer external microphone with Macbook Pro
I have a 13" Macbook Pro with retina display with the OS X El Capitan operating system. So I have a Neewer external microphone that I plug into a 48V Phantom Power box that ends in a jack that fits into the headphone jack. I purchased a 3.5mm M/F adapter in order to be able to have the mic and headphones plugged in at the same time. I want to use the microphone with garageband, but,when plugged in, the only input showing up in system preferences is the built-in internal microphone. Please help me figure out how to get my microphone to work! I have searched all over for answers!
