My MiniMac attempts to eject a CD, in fact, the CD just barely sticks its "nose" out of the slot, but is quickly pulled back in. This is obviously a hardware problem *not software. This MiniMac is at work, and it's possible someone popped in a CD when there was already on in the tray. There's not enough of the CD that comes out to grab onton with tweezers. What do I do?
