It is my understanding that because Sony makes PCs that they have incentive to write software ONLY that will work on their own hardware, whereas since the Macintosh is "competition" to their PC sales, they have a tendency to ignorre Mac users. Be that as it is, I own an iBook and I have Virtual PC on it. It isn't very fast but I am willing to install the PC software that came with my Sony MZ-N707 to see whether this is even possible. I am quite hopeful that it will actually work! My only concern is support for USB in VPC. I have version 5. If it will see the device, I am quite certain that it will work fine. Strange that I have not even tried it before, but I have a PC at home as well, which broke my heart to have to spend money on "that other" operating system and hardware.
Wish me luck! I will be back in touch.
