I've tried toggling the monitor on and off and plugging and unplugging the headphones. I just want to be able to record a track and then layer vocals on top while listening to the first track through headphones. But when I attempt this it seems as though the internal mic becomes disengaged? PLEASE HELP! I just got this new mac a week ago.
