Just had my new iMAC a couple weeks. I was trying to burn some old documents from a flash drive to a CD. When they transferred, I drug the CD to trash to eject it. It went to trash, but didn't eject the CD. It's stuck! When I shut down, my computer just locked up. I finally had to unplug it (I know that's bad, but I couldn't get it to shut down). It came back on and is running fine than goodness, but the CD is still stuck. Please help!
