Sony will never make its minidisc (or cameras, or ...) Mac compatible, unless some pressure is brought to bear. I was shopping for a video camera a few years ago and discovered that Sony's wasn't Mac compatible, but Canon's was. I bought the Canon. Sony has a history of refusing to acknowledge the Mac community.
But wait!!! McDonald's just began it's tie-in campaign with SonyConnect. Unlike Sony, McDonald's is smart enough not to alienate consumers of any ilk. So go to the McDonald's website, to the "contact us" page, and send an e-mail (or letter, if you like) complaining that they have this great promotion but they've locked you out of it. Here's a link to their e-mail form: http://www.mcdonalds.com/app_controller.cu...marketing.html/
I suspect that if they get enough complaints, they'll have a little talk with Sony. :rasp: :rasp:
