I use an early 06 Macbook Pro, 15in. I have been having some issues lately and I was told I should try reinstalling the install DVD to wipe everything and start over. Problem I have is my install DVD is 10.4 and when I moved to this country I didn't bring my 10.5(yes I am freaking retarded) I recently purchased the new 13in Macbook pro for my wife, my question is can I use the install DVD from her computer for my computer? Would that be possible? I really don't want to spend another $150 for leopard and don't want to wait to get my copy sent to me. Any help would be appreciated.
