I had an issue with the MAC OS and couldn't repair the MAC os i have (10.4) on my intel duo core macbook.
So i install Ubuntu 11 on my mac and works perfectly. I am selling my laptop now to get the new macbook pro but the person who wants it needs mac os but every time I try to install it shows a folder with a question mark when I put the mac cd (Original CDs 10.4 that came with the laptop)
so i booted with the "option" and shows my hard drive, put the mac CD and it ejects it, put the ubuntu CD and works perfectly.
I try to clear the nvram: Command + Option + O + F
what can i do to install mac os?
