I am somewhat a new person using a mac and I know this can be done with a windows computer. I was wondering if there is a way to play audio sources from my MBP to an iMac while using the speaker on both computers. Does it revolve around the "Audio MIDI Setup"? In my workplace I can play my music when the customers are not around or if it is after hours. I have my iMac at one side of the store but i'm unable to hear it when I walk into the back. I wonder if I can play my music, from both computer at the same time.
