I've noticed that since my upgrade to SL my PowerShot A590IS isn't working properly. When I try to transfer pictures from the camera to my unibody Macbook, I receive the following message: "Failed to initialize program." I can see my newer photos in the Canon window briefly, and then the error message pops up and closes the window. Has anyone else experienced this? I MRgoogled, and google-googled, and couldn't find anything.
