I have a late mini 2006 2gb ram 1.66ghz. I lost the original discs that came with my mini so no where to run hardware test. I ordered new ones from apple but instead of grey there were white label and black text. One was silver bottom and #2 disk was purple bottom. No big deal. As long as it works. But it doesn't. I called again and they are sending replacement disks again for free. But in the mean time maybe something I'm doing wrong. My mac mini internal matshitacd-rw c- 8124 no longer works. Keeps spitting out cds. But even with external only #1 boots and not disck #2. Even our powermac g5 internal cd works but only #1 shows on boot when holding down option. And #2 does nothing. Which is fine but according to apple hardware test is on # 2 cd and not #1. And holding down d key does nothing.
