One of my beta testers is using a Mac and my
DVC-Tracker program is running fine using VirtualPC. I've had reports that both of my other programs run under VirtualPC on the Mac also.
I'm certain Dave's DVC Manager program will run that way too.
Don't know how many PC programs you want to run on your Mac, but that would be an option. (Don't know what the cost for the VirtualPC program is but I don't think it's that cheap) I think the program is specific by processor, works on some and not others, so you'd need to verify it would work on your machine.
Just a thought.
