Estou fazendo esta pergunta em nome da minha irmã. Aqui está o que ela tinha a dizer no facebook:
Anyone know how to get a DVD unstuck from an iMac drive? I tried everything I read online--shutting down, holding mouse on reboot, trash-dragging, waiting overnight for iMac's temper to cool, a fish hook, a butter knife (ok, maybe not the last two, but I'm about ready to). Please don't make me see a "Genius"! Please PLEASE no "Geniuses"!!!... Waa.
Ela encontrou a resposta. Mais uma vez, vou citá-la (a ênfase é minha):
Finally went to the Geniuses today as a LAST resort to get my DVD unstuck from my iMac. Solution: shut down completely, turn back on and hold the "eject" key down DURING start up until disc pops out! Worked like a champ!

Disk Utility
Launch Disk Utility (Applications > Utilities) and select the troublesome CD or DVD in the sidebar. Click the Eject button at the top of the window.Terminal command
Launch Terminal (Applications > Utilities) and copy the following command:drutil ejectMouse/Trackpad button
Restart your Mac and hold down the left mouse button (or trackpad if you have a laptop) as it boots up. Keep pressing it until the login screen or desktop displays.Tilt and shake
Pick up your Mac laptop and tilt it so the CD/DVD drive is pointing downwards. Restart and hold the Eject key down while gently shaking the computer up and down.The self-fixing Mac
Shut down your Mac, turn it back on, and let it sit for 10-15 minutes. Make sure the power cord is plugged in as you do this and the disc just might pop out on its own.Disrupt the spin
If you listen carefully, you can probably hear your optical drive powering up & down over and over again. As long as the disc spins, it’s not coming out. The first step is to get your hands on a very thin piece of cardboard or even a folded business card (so it’s twice as thick). Now restart your Mac and hold down the mouse/trackpad button as you poke the cardboard inside the SuperDrive slot. The goal is to slip it above the CD or DVD — towards the left side of the drive — and gently jiggle it around to put pressure on the disc. You might have to continue this for up to a minute or so, but it often works when all other methods fail.
Tilt-and-shake provavelmente não é uma boa ideia com um iMac e você tentou segurar o botão do mouse na reinicialização, mas o resto parece valer a pena.
