Resposta para "Disc drive won't let me put a disc in, nothing in there"Guys, I have solved this problem by simple running this line on terminal: drutil tray eject Hope it works. PS & 1st UPDATE (18/10/2016) So... I had the same issue again and I wasn't able to solve it right away. This time I've had (like some of you guys) to run the command several times. I ran it for like 20x before it finally wake up the drive and release it.
