Hello, I have a mac os x 10.5 installed macbook pro. I have to re-install the 10.5 because of some problems. However, I don't have my installation dvds. I am away from my home and my dvds probably got lost in the post office or somewhere during the delivery. I am in Germany. Online apple store doesn't list anything related to OS X except the new 10.8. Making a clean install is OK for me. I will buy a new mac os x dvd. But how? Since my previous OS version is 10.5, I should install 10.6 or 10.7. But how to buy it over internet? Apple store in Frankfurt, does not sell DVDs. Also it is not possible to buy or download the 10.8. So I am need to do to install a new os? Where to buy?
