I bought a used mac mini which was purchased in 2006 with the 1.6 dual core cpu. He didn't have any original install disk's, but he had a burned copy of OS X v10.5 Leopard. So I replaced the HD with a bigger one and put the disk in and basically I'm getting a blinking folder with a ? in it. I don't have a Apple keyboard or mouse. I'm using pc gear. I figure this disk wasn't going to work? How do I get this disk out now? Basically I need to go buy a retail copy of OS X v10.5.6 Leopard ? I haven't had a mac since the 33mhz days so sorry for the stupid questions.
