Sorry Bobbi, we used to have a Mac for a short time but never got deep into it.
I think Curious is good with screen shots - I haven't tried to figure those out either yet.

For the URLs for the files??- are they all bookmarked or favorites? can you email them to yourself or save them online somewhere?

Oh or what about those online storage places- could you upload all your stuff and save it on one of those?
Or would conversion still be the issue?

I hope someone else comes along with better ideas for you.
