I've had the same experience. Didn't work on the Intel MacBook Pro; did work (though only with the older Photo Viewer software linked above: thanks so much) on the old G3 PowerBook (10.3.9).
Somehow, in the process of trying all this out, it actually crashed the MacBook Pro -- right to the grayed screen and the multilingual "You need to restart your computer. Hold down the power button." message. Not going to try that again, and risk blowing up my precious shiny new computer. My wife received this do-dad as a gift, and for all the messing around I've done to put some pictures in it, it seems pretty pointless. If she wants to update it, she's going to have to go through the old computer.
