how to upgrade my os to mountain lion from snow leopard with a os back up
Hi to all in community
Currently am using MacBook with Mac os X 10.6.8 snow leopard. i would like to upgrade to mountain lion and i found the way to upgrade it.
Now am here with an issue, i have the snow leopard os backup software in a cd which i got when i purchased my MacBook in sep' 2010. how can i get the mountain lion backup when i upgrade it, so i can use this backup cd when my os gets crashed or do i need pay $19.XX again to get my mountain lion os?
My Configuration:
processor : Core2Duo
RAM : 2GB
HDD : 250 GB
iPhone 4, iOS 4.3, i am using Mac os x(snow leopard)
