Greeting card factory

If the disk doesnt not say OS X on it, you cannot use it, even if it came with the printer. Check the packaging of the printer, the printer may be compatible, but the software might not, especially if it was "included". You may have been sold a device based on a slick application that you cannot utilize.

If you look up the $50 software, all it says is : Greeting Card Factory Deluxe 7.0 (Win), so I doubt the free version is ripe for OS X. Sorry.
