This is from announcement on individual computers website, published in 2004:
"The Catweasel MK4 has drivers for Linux, Windows 98SE/ME/2000/XP, and Amiga OS 4; additionally, the intention is to support Mac OS X at a later date."
There was an update of the driver software in september 2007, but it looks like there still is no mac driver available.
Maybe the card can work in a mac with a pc emulator, if there is a pc emulator on the mac that is capable of accessing pci slots directly?
