I bought my MacBook Pro during that weird time where I had tiger factory installed but they shipped out free upgrade discs if you purchased it recently. So I upgraded to leopard from the disc and recently I started using Time Machine to back my files up. I haven't had a failure yet but if I do, do I try to run the tiger disc I got with my computer or do I run the upgrade disc even though there isn't a previous version installed.. and please don't say the second one because I have no idea where that disc is lol
