I took my mac mini to the apple store because I had called their tech help and well they didnt help and said to go there. I want to boot from the new leopard install disc I bought. I give it to one of their tech ppl at the store he says he got it to work by pressing down the option key right after the chim. well I tried that it no go. I though it was my apple keyboard so I just went out and bought another and well guess what still no go. I tried the holding c down and I tried rapidly pressing c and option neither worked. Can someone help please. Its a 2007 mac mini late summer.
