I have a new 2010 MacBook Pro, which came with OSX version 10.6.3 installed on it. It also came with the DVDs for re-installing OSX 10.6.3. I also have a 2006 2.16 Ghz MacBook Pro. It used to have OSX 10.4.1 installed on it. The hard drive died, and Apple replaced it. The new hard drive came with system 10.5.8 installed on it. They didn't include DVDs for re-installing the operating system. Is there any reason I shouldn't use my system installation DVDs that came with my new 2010 i7 MBP to install OSX 10.6.3 on my 2006 MBP? Thank you.
