Original 10.4 Tiger install disc keeps ejecting
Hello,
I am trying to re-install my 2007 white MacBook to its original state so I can sell it. It currently has Lion installed, when I insert the original Apple 10.4 Tiger CD/DVD into the super drive the disc just keeps ejecting. All other discs work and the install disc does not eject from my MacMini.
Why is this happening?
How can I get Tiger installed on it from the original disc?
Many thanks in advance for any help provided.
MacBook Air (13-inch, Mid 2012), OS X Mountain Lion (10.8.2)
