Hello Everyone, I really need help. I have a classic mac pro and I restored Snow Leopard on my 8gb usb stick. The stick is recognized on osx and works very well and when the installation process reboots, nothing happens, the usb stick is not recognized on startup, even with the alt command. I tried on other machines and everything is going perfectly except with my mac pro. Can you plz guys tell me how can I make my mac pro (classic) recognize my usb stick on startup ? Thank you very much for your help.
