Can you remove the SD card from the Canon and insert into your SD slot on the iMac? If not, a USB card reader should work OK.

The best of Vista is not even in the same league with any version of OS X.

The camera uses a cf card not sd card so can't plug card into computer. Needing to remove card from camera is so 80's. Besides with leopard on the mac mini i had before this I could just plug in the camera and it was seen as usb volume and I could download pics - no fuss no muss. So i need to reconfigure something or Lion has taken a step backwards. **** I can plug the camera into an old amiga and download quickly. But I want to do it on my work machine- the iMac.
thanks for trying.
