Agree with Capt Claret - except i use VMWare Fusion - it allows your mac to run JeppView as though it was a mac piece of software (technically it it still running it in windows, but you don't "see" the interface - you just get an icon in the dock for Jepp).
Personal opinion - Fusion is best if you have just or two windows only programmes (like Jepp), and Parallels is better if you want to actually have a windows desktop on your mac.
