I have a Mac mini 10.6.8. The mac worked great but after about a year it just stopped reading Cd's and DVD's. It makes a noise as if it's trying to read and then there is a grinding noise which it might repeat several times then spits the CD out. There is a possibility that the cd rom program was deleted when the computer was being "cleaned up" so I was wondering if someone could give me some pointers wether or not the rom is broken or if I need to download the program again.... I really need to download a program via CD!!!! Thanks for any help!
