Two questions: 1) True or False: Do the new 13" aluminum MacBooks come with an unreleased build of Leopard? 2) The 200GB 7200 RPM Hitachi hard drive on my white plastic Santa Rosa 2.2 GHz MacBook is running the latest version of Leopard (10.5.5). When I originally installed Leopard when it came out, I did a clean install (aka "erase and install") which was a full install of literally everything that could possibly be installed. I run Software Update regularly, and have always downloaded everything that Software Update listed (regardless of whether I needed it or not). So here's my question: If I buy a new 13" aluminum MacBook, can I just take my old hard drive out of my previous generation MacBook and pop it into the new aluminum MacBook, and just start using it without having to reinstall anything or installing anything new?
