So I have a MacBook Pro with El Capitan 10.11.6 and the dvd drive started being funny a few weeks ago. It now spits out discs that it used to read. *Not all discs. It still reads some but not all.* They’ll spin for a few seconds and you’ll hear it try then it spits it back out. These are dvds that we have watched before, not blu rays or anything. I tried resetting the PRAM hoping that would help and it did not.
