Hi, I currently have a 27" iMac late 2013 model. I'm planning on purchasing a Macbook later this year and connecting it to the iMac via Target Display Mode. I've read somewhere that TGM allows the Macbook to use the audio of the iMac. With that said, is the Macbook only able to use the built-in speakers of the iMac or can it use any other digital audio devices that are connected to the iMac? For example, I have a pair of powered studio monitor speakers connected to an audio interface which the interface is connected to the iMac. Can the Macbook access the studio monitors via Target Display Mode?
