Hello, I have a G5 Tower with 10.3 on it right now. I have 10.5.8 and I put in the DVD DL to install. But the primary disk drive on this computer doesn't read dual layer. So we got a dual layer driver to connect through usb. But the problem is that after we click install and it reboots it goes to the default driver... which doesn't work. So I was wondering if it was possible to change the default driver?? Or how can I get this to work?? thank you for reading my issue and I hope you can help!
