It works fine, but you have to jump through a few hoops to get round OS 
X's automatic mounting of cards.

What you do is:

Plug the card in via the card reader. Use the Disk utility to see where 
it's been mounted - different brands of card seem to come up as 
different disks, but usually it's something like /dev/disk2 or 

Unmount the card, if Os X has mounted it - you can use Disk Utility to 
do this.

Since Disk Utility can read .iso images you should be able to use that, 
but I haven't got that to work, so I have to use terminal.

Run a terminal, su to root, so you can write to the card and do the 
same as the Unix instructions say:

# pkunzip <mono iso file> | dd of=/dev/disk2 bs=16K

(Assuming the card appeared as /dev/disk2).

Then there will be 30 seconds of activity for the card reader, and it's
