Hi Walker,
That message looks like bad news for me too, I have an Artec Ultima 2000, which is basically the same scanner in a different casing without the iMac colours, and uses the same drivers. If anyone else has an Artec scanner, maybe we can get some "people power" to get Artec to change their mind. Sending Artec a request email for OS X drivers could be the best way of doing it (nothing aggressive though, that could be counter-productive). Post here if you have an Artec scanner, and even if you don't post here for the "OS X compatible" cause. We've got to do something, haven't we?
