My Mac Pro is OOW and the Super-drive is having issues where it won't recognize discs inserted at times. I can't get them to eject by any other way but reboot and then they auto-eject. I assume that the drive is bad, and the quote from Apple is $69.00 for a new Super-drive. They suggested that some third party drives would work well also, and would obviously be less expensive. What DVD writers work with OSX? I've never had to swap a drive like this before. Someone said to get a Samsung drive for some reason. No one stocks them, and I've seen multiple brand of drives that look exactly the same so who knows who actually made them... Thanks!
