I was installing X-Plane 9 on my fairly new mac pro when it stopped working. I switched disks and nothing happened, the drive just won't spin up. I have tried a number of different CDs and DVDs and none will spin up. I can verify that by looking at the position of the disk when I put it in and take it out, it never moves. I have tried the usual reboot and resetting the PRAM. (I did the command option o r and un-plugged with power button for 5 seconds) I tried calling Apple care 2 times and the message I get is, the call center is closed. That's it, they don't even tell what hours they *ARE* open. I would really rather not try and lug this to the Apple store, I have a bad back and would need to do it via cab ... which has you can imagine, wouldn't be the best of ideas. Any ideas on things I can try ? This is really driving me nuts.
