Disklavier

My wife and I just purchased a DU1A and are having it delivered in  
the coming week.  Yay!!!!!  We used the archives on this group to  
help us decide to take the plunge.  Thank you for all the info you  
have shared with this list.

My question for the group is, does anyone have experience working  
with a Macintosh computer and the Pianosoft files and MIDI files?  On  
the Yamaha Pianosoft site it appears that you can only download disks  
on a Windows machine.  Has anyone found a workaround for this (aside  
from using a program like Parallels or Boot Camp to boot Windows XP  
on a macintosh).  Also if I download MIDI files or the files from the  
files section of the User Group can I just format a disk as Windows  
format and save the files to a floppy disk on an external USB drive  
and then use that disk in the piano?

Any help on making files on the Mac work with the piano would be very  
appreciated.

Thanks,
Jared
