She has a really old 13 mbp I think I has like a 2.0 ghz processor and 2 gigs of ram and a 150gig hard drive! I couldn't believe it. So my questions are as follows. I have a new mbp see specs below. Can I upgrade her mbp using my 8gigs of 1333mhz ram and then just get myself some 1600? Two birds w one stone would be nice. I know it's tough to say with out the model year but I'm Hoping someone will recognize the specs Thanks! I'll check back later, can someone tell me how to determine the model year of her mbp? I see model years written as 2 numbers Like 8,3 what's that?
