OK, I've looked through the Geek Squad website and have seen no indication that they work on Apple Macs. Is this so? The reason I'm searching is that I was watching cable last night and at the very beginning of a Geek Squad commercial is a woman sitting behind a desk hitting some keys on her keyboard. However, her computer is repeatedly making the sound of the Mac OS 9 error chime. It was either the "basso" or "sosumi." Anyone else noticed this ad before?
