So i got my macbook back from the police who found it, they flushed verything on the harddrive. Now i open the mac and it comes up to the loading apple, but i cant put the software install cd inside because i think a cd is already in. Itried opening it and holding down the trackpad, and i hear the cd drive whirring like crazy trying to spit it out but its not. Is there really a CD stuck inside or does it just not work anymore??
