2009 white macbook. I tried to insert it and I don't even think it recognized the disk. have tried all the recommendations I have found on MR, restarting, terminal, etc. It just does not show up anywhere on the computer. I have seen a couple of people mention a manual eject button inside the slot, but I have not seen anyone describe where to find it. I don't want to break anything grinding around a credit card or paper clip without knowing what to look for.
