Hi I bought a bose companinon 5 2 years ago and believe it or not today was the 1st day i have removed it from the box. I have followed the osx audio set up proceedures: been into system preference and higlited Bose usb audio as sound output. Then into applications folder opened utilities folder; then Audio MIDI setup at which point everytime I try to open Audio Midi Setup the program unexpectedly quits and I cannot proceed any further. Has anybody got a solution to this problem. Many thanks in anticipation of your help
