I was playing around with GarageBand on a friend's computer (a 20" iMac) and it came up with this error message. It's kind of sad that Apple's high-end consumer machine can't handle a consumer-level app. Has anyone else seen this before? By the way, I know when GB was announced, I didn't have many kind things to say about it. I still don't know how well it will sell, but it is quite a cool app to just play around with. I probably wouldn't spend $50 on it, but it is an interesting idea.
