Do you have Classic in your computer? Then you can still run these utilities. I haven't tried Macinstaller, so I don't know if that works in OSX, but Maconverter does. Also, not everything needs converting. It's only the preview rsr's that don't work in P5 on the Mac. If you download something with png's you can install it right away. P5 will "see" the cr2's etc even if the icons are wrong, as it looks at the file name endings to decide what file type it is.
