Hello everyone. I just bought my first Mac today, so hopefully I'll be posting here for quite a while. I bought a used Macbook Core 2 Duo 2.0. I bought it knowing the drive needs to be replaced, but everything else works perfectly. I still have one problem: I cannot manage to run the Mac OSX install disks that came with the computer through an external DVD drive. I hope somebody can help me. The DVD drive is recognized by the computer when I load a movie or music CD, but when I load the install disk nothing happens. I even leave the disk on the drive, turn the computer off, and then restarted and press the C key down during the boot, but nothing happens either... Thanks for your help in advance.
