Hey all, I'm unable to transfer images from my Canon PowerShot SD990 IS to my iMac (OSX 10.5.6, 2.4 GHz, 1 GB). I know they're connecting because I can see the pictures on my iMac when they connect. However, whenever I try to download them to the iMac, it fails and tells me something along the lines of transfer failed. -I tried connecting to another USB port, same problem. -I downloaded the most recent software updates from Canon for the camera, same problem. Thanks in advance.
