I want to reset my MacBook Pro. I've the required Installation CD and the certain key-combination. The problem is that the Mac ejects the CD every time. If I press c while restarting the Mac nothing happens. Where's the problem? Thanks for your answers!
I would suggest you take the computer in to a see an Apple Genius. They can test the optical drive and quote a price to fix it. They can also reinstall Snow Leopard for you (make sure you have a backup of data.) Alternatively, you could buy a external USB CD drive.
