hello,
is there a share client for OS X?
I highly doubt it since macs are quite rare in Japan (although recently gaining popularity). Since I don't PC game this is about the only thing that has me considering bootcamp/parallels.
Share only runs on Windows (it still does not work under Wine, unlike Perfect Dark), so your only hope (as said by post 2) is Parallels, VMWare, or for a more drastic solution, Boot Camp.
All solutions require a MacIntel, so PPC users are out of luck :(
