Hey, When I put CDs of any type in my macbook, the computer spits it right out. It stays inside for a bit and then comes out again. I have a macbook 10.4.11 What are my options? Im sure if I repair my mac its going to be a big bill. How about if I got an external CD drive? Which ones are good that would be compatible with my macbook? My macbook is three years old. Thanks.
