Quote - MarianneR: Is there by chance an rsr-png conversion program, or do I have to just deal with no preview thumbs?

I found a helpful little freeware application called RSRConv that I've just started using that will convert .rsr files to .png files on Mac OS X if needed. It also has a widget for Dashboard. You can download it here: http://braintrigger.com/software/RSRConv/ Good luck with your Mac adventures. :)
