I want to buy my boyfriend an audio interface for xmas but I have no idea which one to buy. He just has a simple macbook and I have been told about the fosucrite saffire 6 usb. Would this work with his macbook? He is studying music tech (djing & producing etc). I do not have a high budget as I am only a student and I actually have no idea what all this stuff is and is used for...so simple answers will really help me out.. Thanks.
