> though on my old mac, ive got the pre usb dongle and have to occasionally reauthorize using the original software CD. is it 100% definite that i need the dongle to use SD on a new mac or will the original program CD do?? As I mentioned earlier you ***need*** XSKey in order to run SD Public Beta under OS X. OTOH your CD is required to reauthorize SD under Windows in the same way you did it in OS 9 days. Best, Andy
