It has a 2.16 GHz Intel Core 2 Duo and 2 GB 667 MHz RAM. The guy I bought it from couldn't find the start up disk but that is besides the point. I know this is a old software. I have 2 questions: - Would it be cheaper to take it to the Mac Store and have them update it up to the current software or buy each one and do it myself? - How can I free up disk space, I did try to buy an update but the macbook wouldn't install because of lack of disk space This is my first mac so please provide in window terms...LOL!
