I used a (?) as I am not sure what the year is. It is the last version of the pre-unibody that still has Home-End, and Page Up/Down on the keyboard. I am going to refurbish it for my mother and I have already upgraded it to 4GB of RAM. What I would like to know is, should I put 10.6.8 or 10.7.4 on it, and what hard drive should I use? I believe it is SATA 1.5 so an SSD or hybrid drive would be almost pointless right? I'm thinking of a Western Digital Blue drive, and 10.7.4 just so she doesn't have to worry about compatibility. She is moving form a PC with Windows 7 and will only be using Office, Mail, and the internet. Perhaps I have just answered my own questions?
